The following are the changes from calc version 2.12.7.1 to date:
Corrected CHANGES notes that were mixed up for TAB, VT, CR &
NL. The code in 2.12.7.0 is correct. The CHANGE notes should
have read:
The following is a partial list of escape sequences recognized
in strings and in printf formats:
\a audible bell byte 0x07 in ASCII encoding
\b backspace byte 0x08 in ASCII encoding
\f form feed byte 0x0c in ASCII encoding
\n newline byte 0x0a in ASCII encoding
\r return byte 0x0d in ASCII encoding
\t tab byte 0x09 in ASCII encoding
\v vertical tab byte 0x0b in ASCII encoding
Fixed a segfault when getpwuid() returned NULL during initialization.
Thanks goes to baratharon GitHub user for reporting this issue.
The following are the changes from calc version 2.12.6.10: to 2.12.7.0:
Added a patch to replaces the manual search for include files
in $(INCDIR) in the have_*.h targets with compiler invocations.
Thanks goes to Helmut Grohne (helmut at subdivi dot de) who
implemented the patch and posted it to the Debian bug tracker
and Martin Buck (m at rtin-buck dor de) for forwarding it to us.
The check_include make rule was fixed to not assume /usr/include.
The qprintnum() function now takes outdigits as a 3rd argument.
Most of the time, this 3rd argument is just conf->outdigits.
But when it comes to the experimental '%g', this value can
change. This avoids having to modify conf->outdigits.
Fixed a problem where gcc complains about E_FUNC not being defined
for Linux systems as reported by Martin Buck (m at rtin-buck dor de).
Updated the help files help/config, help/display, help/epsilon,
help/fprint, help/printf, and help/strprintf to give more
examples of how display digits and epsilon precision interact
with displaying values.
Added more information about %g in the help file help/printf.
The '\a' is now recognized in a printf format string as the
single byte audible bell character (byte 0x07 in ASCII encoding).
The following is a partial list of escape sequences recognized
in strings and in printf formats:
\a audible bell byte 0x07 in ASCII encoding
\b backspace byte 0x08 in ASCII encoding
\f form feed byte 0x0c in ASCII encoding
\n newline byte 0x0a in ASCII encoding
\r return byte 0x0d in ASCII encoding
\t tab byte 0x09 in ASCII encoding
\v vertical tab byte 0x0b in ASCII encoding
The following are the changes from calc version 2.12.6.9 to 2.12.6.9:
Fixed a number of core dump bugs related to the calculation of
tan(), cot(), sec(), csc(), tanh(), coth(), sech(), and csch(),
asin(), acos(), asinh(), acosh(), where when a call to an
underlying function produced an invalid value. Thanks goes to
github user wuxiuheng for reporting this problem.
A number of trigonometric and hyperbolic functions that incorrectly
returned E_LOGINF, now return a new error code that is more
specific to the trigonometric or hyperbolic function. The
following is a list of these new error codes: E_TAN3 E_TAN4
E_COT3 E_COT4 E_SEC3 E_CSC3 E_TANH3 E_TANH4 E_COTH3 E_COTH4
E_SECH3 E_CSCH3 E_ASIN3 E_ACOS3 E_ASINH3 E_ACOSH3 E_ATAN3 E_ACOT3
E_ASEC3 E_ACSC3 E_ATANH3 E_ACOTH3 E_ASECH3 E_ACSCH3.
Added regression tests 3729 thru 3732 to test E_TAN3, E_COT3,
E_SEC3 and E_CSC3 respectively.
Added experimential %g printf (and strprintf) format implementation
based on pull request from github user 10110111.
Made exterimental changes to macOS builds to not require use of
/usr/include. The INCDIR for macOS uses:
INCDIR= $(shell xcrun --show-sdk-path --sdk macosx)/usr/include
to determine the upper path of the /usr/include directory for macOS.
In some rare cases, the Darwin target seems to not automatically detected.
If you are running under macOS, and that happens, you can force
the target to be Darwin:
# for macOS users only, force the target to be darwin
#
make target=Darwin clobber
make target=Darwin all
make target=Darwin chk
make target=Darwin install
The following are the changes from calc version 2.12.6.6 to 2.12.6.8:
For historical purposes, in lucas.cal, gen_v1(1, n) always returns 4.
Fixed some compiler warnings, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Added work around for a gcc warning bug, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Fixed errors in various help files such as:
mat randbit seed srandom types
Removed the MAXSTRING symbol because it was no longer used by calc.
Increased HIST_SIZE (depth of the history stack) from 10k to 32k.
Increased TTYSIZE (reallocation size for terminal buffers) from 100 to 8191.
Increased MAXDEPTH (maximum depth of input stack) from 10 to 255.
Increased interactive input buffer size from 1024 to 256k. This has the
effect of increasing the maximum length of an input line from a tty.
This helps with an interactive bug that was reported by Ruslan Kabatsayev
(b7 dot 10110111 at gmail dot com).
The calc man page indicates that -d also disables the printing of the
leading tilde.
Added information to "help command" about how to silence messages
while reading calc resource files.
Fixed an error message buffer overflow thanks to a report by
Frank Peters <nlp at northernlightsphoto dot biz>.
Replaced all use of the C funcion sprintf() with snprintf().
Replaced all use of the C funcion vsprintf() with vsnprintf().
Replaced all DONT_HAVE_VSPRINTF with DONT_HAVE_VSNPRINTF.
Replaced all Makefile var ${HAVE_VSPRINTF} with ${HAVE_VSNPRINTF}.
The following are the changes from calc version 2.12.6.4 to 2.12.6.5:
Fixed warning about undefined operations involving the qlink(q)
macro by replacing that macro with an inline-function. Thanks goes
to David Haller <dnh at opensuse dot org> for this fix.
NOTE for Windows 10 users: Pavel Nemec <pane at seznam dot cz>
reported that calc version 2.12.6.4 has been successfully
compiled, installed and running on Windows 10. See README.WINDOWS
for more details.
The following are the changes from calc version 2.12.6.1 to 2.12.6.3:
Improved gen_v1(h,n) in lucas.cal to use an even faster search method.
Improved are checking in lucas.cal. In particular both h and n must be
integers >= 1. In the case of both rodseth_xhn(x, h, n) and gen_v1(h, n)
h must be odd.
Fixed an C code indenting issue that was reported by Thomas Walter
<th dot walter42 at gmx dot de> in zfunc.c.
Fixed a man page warning about ./myfile where the leading dot
was mistook for an nroff macro. Thanks goes to David Haller
<dnh at opensuse dot org> for providing the patch.
Improved gen_v1(h,n) in lucas.cal for cases where h is not a
multiple of 3. Optimized the search for v(1) when h is a
multiple of 3.
Fixed a Makefile problem, reported by Doug Hays <doughays6 at gmail
dot com>, where if a macOS user set BINDIR, LIBDIR, CALC_SHAREDIR
or INCDIR in the top section, their values will be overwritten by
the Darwin specific section.
The following are the changes from calc version 2.12.6.0 to 2.12.6.0:
Added the makefile variable ${COMMON_ADD} that will add flags
to all compile and link commands. The ${COMMON_ADD} flags are
appended to both ${COMMON_CFLAGS} and ${COMMON_LDFLAGS}. This
facility is available to nearly all platforms except those with
very old make commands that do not understand the += operator.
Example on macOS (Darwin), one may invoke clang's -fsanitize
facility by:
make clobber all \
COMMON_ADD='-fsanitize=undefined -fsanitize=address'
Another example. To force C warnings to be treated as errors:
make COMMON_ADD='-Werror'
Created a GitHub repository for calc:
https://github.com/lcn2/calc
NOTE: The calc GitHub repository represents the an active
development stream. While an effort will be made to keep
the master branch of the calc GitHub repository in working
order, that tree may be unstable. Those wishing for more
reliable releases use releases found at calc mirror sites:
http://www.isthe.com/chongo/tech/comp/calc/calc-mirror.html
IMPORTANT NOTE:
On 2017 June 05, the calc GitHub history was re-written.
Anyone who was tracking the calc "pre-release" on GitHub prior
to version 2.12.6.0 should do a:
git reset --hard origin/master
git cleanup -f
Or you may just want to start over:
rm -rf calc
git clone https://github.com/lcn2/calc.git
Sorry about that. The previous GitHub repository was an useful
experiment. Based on what we learned, we decided to rebuild it.
Renamed README to README.FIRST. Added README.md for the
GitHub repository.
Fixed reading from standard input (stdin) when -p is given on
the command line. This now prints hello:
echo hello | calc -p 'stdin = files(0); print fgetline(stdin);'
Added more debugging related to stdin when bit 4 of calc_debug
is set (e.g., running calc with -D16).
Updated the calc(1) man page and 'help file' to explain about
reading from standard input (stdin).
Added some clarifying remarks for 'help ptest' explaining that
the ptest builtin can return 1 is some cases where the test
value is a pseudoprime.
Removed duplicate copyright comments from the help/builtin that
is built.
Fixed a number of typos in the CHANGES file.
The following are the changes from calc version 2.12.5.4 to 2.12.5.6:
Recompile to match current RHEL7.2 libc and friends.
Added fix by Alexandre Fedotov <fedotov at mail dot desy dot de>
to prepend ${T} in front of the CALCPATH path components
${CALC_SHAREDIR} and ${CUSTOMDIR}. Add ${T} in front of ${HELPDIR}
and ${CUSTONHELPDIR} when making conf.h.
Improved the jacobi help page.
Rewrote gen_v1() in the lucas.cal resource file using the method
based on a paper:
"A note on primality tests for N = h*2^n-1", by Oystein J. Rodseth,
Department of Mathematics, University of Bergen, BIT Numerical
Mathematics. 34 (3): pp 451-454.
http://folk.uib.no/nmaoy/papers/luc.pdf
The improved gen_v1() function is capable of returning a value
for all valid values of h and n. As a result, the trial tables
used by gen_v1() have been changed to a short list of values
to try, in order ot likelyhood of success, before doing an
exhaustive search for a v1 value to return.
Removed lucas_tbl.cal calc resource file. This file was made
obsolete by the above rewrite of the lucas.cal resource file.
This file will be removed from the local cal directory and
from CALC_SHAREDIR during a 'make install', 'make clobber',
and 'make uninstall'.
Renamed gen_u0() to gen_u2() in lucas.cal. Provided a gen_u0()
stub function that calls gen_u2() for backward compatibility.
The old gen_v1() method used by the Amdahl 6 group has been
renamed legacy_gen_v1() in lucas.cal. This function is no
longer used by the lucas(h, n) function to test the primality of
h*2^n-1. It is preserved in lucas.cal for historical purposes.
The 'make clobber' rule will attempt to remove all files that
start with libcalc and start with libcustcalc.
The 'man' command is now an alias for the 'help' command.
Fixed extra /'s that were put into CALCPATH because of ${T}.
Fixed extra /'s that were compiled into HELPDIR and CUSTOMHELPDIR.
The fix in 2.12.5.4 to to prepend ${T} in front of the CALCPATH
path components ${CALC_SHAREDIR} and ${CUSTOMDIR} broke the
calc rpm build process. The check-buildroot tool discovered
that the BUILDROOT directory had been improperly put into various
paths and binaries. This has been fixed in 2.12.5.5.
Fixed a crash that showed up on macOS (Darwin) that was reported
by Richard Outerbridge <outer at interlog dot com> and
fixed by Stuart Henderson <stu at spacehopper dot org>.
Thanks goes to both!
The following are the changes from calc version 2.12.5.3 to 2.12.5.3:
Calc version 2.12.5.2 for macOS (Darwin) users, code to installed
calc under /opt/calc. Moreover the CHANGES file did not mention
/opt/calc. Sorry about that!.
A much better tree for macOS (Darwin) users would have been
to install cal under /opt/calc. This release ONLY changes the
macOS (Darwin) install tree to /usr/local.
macOS (Darwin) users who installed calc version 2.12.5.2
should, after installing version 2.12.5.3:
rm -rf /opt/calc
The following are the changes from calc version 2.12.5.1 to 2.12.5.2:
NOTE: calc version 2.12.5.2, for macOS (Darwin) users,
installed under /opt/calc. We neglected to mention this
AND /usr/local would have been a better choice. Sorry!
Fixed in calc version 2.12.5.3.
Removed rules and makefile variables associated with shortened
calc version numbers of less than 4 levels.
Under OS X (Darwin), if /usr/include is missing, warnings
are issued to help the user use xcode-select --install
so that one may properly compile C code.
Lowered REDC levels:
#define MAXREDC 256 /* number of entries in REDC cache */
#define SQ_ALG2 28 /* size for alternative squaring */
config("sq2") == 28 /* was 3388 */
#define MUL_ALG2 28 /* size for alternative multiply */
config("mul2") == 28 /* was 1780 */
#define POW_ALG2 20 /* size for using REDC for powers */
config("pow2") == 20 /* was 176 */
#define REDC_ALG2 25 /* size for using alternative REDC */
config("redc2") == 25 /* was 220 */
The alg_config.cal script appears to be not correctly finding the
best REDC values. While it has been improved, alg_config.cal still
seems to be suspect on how it attempts to find the best values.
Fixed an intro help file mistake found by Roger Hardiman
<roger at rjh dot org dot uk>.
The following are the changes from calc version 2.12.5.0 to 2.12.5.1:
Calc has a new calc-tester mailing list. This list is for those
who are using/testing calc. We also use this list to announce
new versions of calc. To subscribe to the calc-tester mailing
list, visit the following URL:
http://www.isthe.com/chongo/tech/comp/calc/calc-tester.html
This is a low volume moderated mailing list.
This mailing list replaces calc-tester at asthe dot com list.
If you need a human to help you with your mailing list subscription,
please send Email to our special:
calc-tester-maillist-help at asthe dot com
address. To be sure we see your Email asking for help with your
mailing list subscription, please use the following phase in your
Email Subject line:
calc tester mailing list help
That phrase in your subject line will help ensure your
request will get past our anti-spam filters. You may have
additional words in your subject line.
There is a new calc bug report Email address:
calc-bug-report at asthe dot com
This replaces the old calc-bugs at asthe dot com address.
To be sure we see your Email reporting a calc bug, please use the
following phase in your Email Subject line:

That phrase in your subject line will help ensure your
request will get past our anti-spam filters. You may have
additional words in your subject line.
However, you may find it more helpful to simply subscribe
to the calc-tester mailing list (see above) and then to
send your report to that mailing list as a wider set calc
testers may be able to help you.
The following makefile rules that were related to printing the
upper values of the calc version, rules that were made obsolete
in calc version 2.12.4.14, have been removed:
calc_vers calc_ver calc_ve
vers ver ve
Noted that the hash() builtin function, internally known as
quickhash (used for internal objects such as the associative
arrays as well as other internal processes) uses the deprecated
32-bit FNV-0 hash. The use of this deprecated hash is sufficient
for calc internal purposes. Use of FNV-1a is recommended for
a general non-cryptographic quick hash.
The following are the changes from calc version 2.12.4.14 to 2.12.5.0:
For Apple OS X / Darwin target:
MACOSX_DEPLOYMENT_TARGET is no longer defined
using clang compiler
By default, -install-name is used when forming shared libs.
To force -install-name to not be used, set SET_INSTALL_NAME=no.
The have_stdvs.c test uses <stdlib.h> and fixed va_start() test call
that didn't use last arg.
Fixed math_fmt (printf) in value.c where a LEN (SB32) be printed as %d.
Fixed a significant bug where that resulted in an incorrect
complex number comparison. Thanks goes to David Binderman
<dcb314 at hotmail dot com> for identifying the subtle typo!
Make minor fixes to the make depend rule.
Fixed places were calc defined a reserved identifier that
begin with either __ or _[A-Z]. For example, __FILE_H__ has
been replaced with INCLUDE_FILE_H.
Fixed the addall3 example in the script help file. Thanks for this
fix goes to Igor Furlan <igor dot furlan at gmail dot com>.
We made important fixes to the calc command line history:
Fixed a bug in the command line history where calc would sometimes
crash. There was code that used memcpy() instead of memmove()
that could corrupt the command line history when entering a
into into history that was similar to a previous entry. Thanks
goes to Einar Lielmanis <einars at spicausis dot lv> for first
identifying this mistake.
The calc command line history code, in general was not robust.
We made use a patch from Mathias Buhr <napcode at users dot sf
dot net>, that while it uses a bit more memory: is much more
flexible, readable and robust. This patch replaced the improper
use of memcpy() (see above) with better code. Thanks!
The alg_config.cal calc resource file has been reworked to produce
better diagnostics while attempting to determine the ideal values
for mul2, sq2, and pow2. However, it has been shown that this
code is not correct. Suggestions for a replacement are welcome!
calc -u 'read alg_config; config("user_debug", 2),; best_mul2();'
calc -u 'read alg_config; config("user_debug", 2),; best_sq2();'
calc -u 'read alg_config; config("user_debug", 2),; best_pow2();'
Fixed a number of pedantic compiler warnings.
Removed -W and -Wno-comment from the the CCWARN makefile variable.
Removed no_implicit.arg makefile rule. Removed HAVE_NO_IMPLICIT
makefile variable. Removed no_implicit.c source file.
Added WNO_IMPLICT makefile variable to hold the compiler flag
-Wno-implicit for use on selective compile lines.
Added WNO_ERROR_LONG_LONG makefile variable to hold the compiler flag
-Wno-error=long-long for use on selective compile lines.
Added WNO_LONG_LONG makefile variable to hold the compiler flag
-Wno-long-long for use on selective compile lines.
The makefile variable ${MKDIR_ARG} has been replaced with just -p.
Minor fixes were made to the calc.spec.in file.
The target rpm architecture changed from i686 to x86_64. For those
who do not run machine with x86_64, we continue to release a src
rpm. For those without the ability to process an rpm, we will always
to release src tarball.
When building the libcalc and libcustcalc shared libraries,
ONLY the .so and .so.${VERSION} files are created. The .so is
a symlink to the .so.${VERSION} file. Here ${VERSION} is the
full "w.x.y.z" calc version.
The following are the changes from calc version 2.12.4.11 to 2.12.4.13:
Fixed many typos in comments of the Makefile thanks to the review
work of Michael Somos.
Fixed typo in "help sysinfo".
The Makefile rule, debug, is now more verbose and prints more information
about the calc compiled constants.
Added a more of calc resource files by
Christoph Zurnieden <czurnieden at gmx dot de> including:
infinities.cal - handle infinities symbolically, a little helper file
intnum.cal - implementation of tanh sinh and Gauss-Legendre quadrature
smallfactors.cal - find the factors of a number < 2^32
strings.cal - implementation of isascii() and isblank()
Reformatted some calc resource files. Cleanup in comment the headers
of some calc resource files.
Minor formatting changes to a few help files.
No need to be special picky about the test8900.cal calc resource file.
Added a number of ctype-like builtins:
isalnum - whether character is alpha-numeric
isalpha - whether character is alphabetic
iscntrl - whether character is a control character
isdigit - whether character is a digit character
isgraph - whether character is a graphical character
islower - whether character is lower case
isprint - whether character is a printable
ispunct - whether character is a punctuation
isspace - whether character is a space character
isupper - whether character is upper case
isxdigit - whether character a hexadecimal digit
strcasecmp - compare two strings, case independent
strncasecmp - compare two strings up to n characters, case independent
strtolower - transform an ASCII string to lower case
strtoupper - transform an ASCII string to upper case
For details on these new builtins, see their help messages.
Thanks goes to Inge Zurnieden <inge dot zurnieden at gmx dot de> for
these new builtins.
Calc source code is now picky v2.3 clean using:
picky -s -v file file2 ..
With the exception of:
help/errorcodes.sed
cal/set8700.line
Due to the long lines in those files, we use:
picky -w -s -v help/errorcodes.sed cal/set8700.line
For more information about the picky tool, see:
http://cis.csuohio.edu/~somos/picky.html
Removed functions from strings.cal that have been replaced by
the new ctype-like builtin functions.
Fixed cal/Makefile to include missing intnum.cal file.
Added detail_help_list make target to cal/Makefile.
The detaillist make target in help/Makefile is now
called detail_help_list.
Removed requirement of gen_u0(h, n, v1) in lucas.cal that h
be odd. While still lucas(h, n) converts even h into an odd h
internally by incrementing n, gen_u0(h, n, v1) will output even
when h is even.
The following are the changes from calc version 2.12.4.6 to version 2.12.4.10:
Updated RPM build process to remove use of deprecated flags.
Applied a number of fixes to calc.spec and rpm.mk file.
See calc.spec.in for details. Changed rpm release to 2.1.
Set MACOSX_DEPLOYMENT_TARGET=10.8 as we upgraded all of
our development Mac OS X to 10.8.
Libraries are chmod-ed as 0644 to allow for building rpms
without root.
Silenced annoying warning about unused variable 'intp'
while compiling endian.c under some circumstances.
Fixed typo in redeclaration warnings. Thanks to
Christoph Zurnieden <czurnieden at gmx dot de> for this report.
Added a number of calc resource files by
Christoph Zurnieden <czurnieden at gmx dot de> including:
bernpoly.cal - Computes the nth Bernoulli polynomial at z for any n,z
brentsolve.cal - root-finder implemented with the Brent-Dekker trick
factorial.cal - product of the positive integers
factorial2.cal - variety of integer functions quasi-related to factorial
lambertw.cal - Computes Lambert's W-function at "z" at branch "branch"
lnseries.cal - Calculates a series of natural logarithms at 1,2,3,4...n
specialfunctions.cal - Calculates the value of the beta function
statistics.cal - a wide variety of statistical functions
toomcook.cal - Multiply by way of the Toom-Cook algorithm
zeta2.cal - Calculate the value of the Hurwitz Zeta function
Fixed a makefile bug that prevented the those new calc resource
files from being installed.
Improved the formatting of the output from:
help resource
We replaced COPYING-LGPL with the version that is found at
http://www.gnu.org/licenses/lgpl-2.1.txt because that version
contains some whitespace formatting cleanup. Otherwise the
license is the same.
We fixed a number of places where "the the" was used
when just "the" should be used.
NOTE: Fixes to grammar, spelling and minor formatting
problems are welcome. Please send us your patches!
With the exception of 3 source files, we became "picky" about
line lengths and other issues reported by the picky tool:
cal/test8900.cal
cal/set8700.line
help/errorcodes.sed
The above 3 files now pass picky -w (OK except for line length).
For more information about the picky tool, see:
http://cis.csuohio.edu/~somos/picky.html
The following are the changes from calc version 2.12.4.3 to 2.12.4.5:
Added gvec.cal resource script.
Added calc-symlink make rule to setup symlinks from standard locations
into a tree specified by a non-empty ${T} makefile variable. Added
calc-unsymlink to remove any symlinks that may have been created by
the calc-symlink rule.
If is OK for the calc-symlink make rule to pre-remove a symlink.
Fixed bug was uncovered in calc that caused script failures when calc
is called within a while loop in BASH if the while loop is fed from
stdin due to calc's redirection/inheritance of stdin and no option
to change this behavior. Thanks gores to David C. Rankin
<drankinatty at gmail dot com> for the bug fix and to David Haller
<dnh at opensuse dot org> for helping debug this problem.
The following are the changes from calc version 2.12.4.0 to 2.12.4.2:
Fixed a documentation bug for the sgn() builtin.
Added the 1<<8/2 evaluation example to "help unexpected". That
expression evaluates to 128, not 16 as some C programmers might expect.
Fixed a bug in solve.cal where high was not returned in some situations.
Fixed a bug reported by Paul & Karen Tomlinson (paulnkaz at pktomlinson
dot fsnet dot co dot uk) where calling log multiple times with different
values of epsilon resulted in an incorrect value.
Removed cvd rule from Makefiles.
The Makefile used in the source rpm (calc-*.src.rpm) no longer uses
the -Werror compile flag. This is to help those distributions with
compilers that make produce (hopefully) compilation warnings.
NOTE: For testing and calc build purposes will recommend and will
continue to use the -Werror flag.
Fixed a typo in the Makefile where the make variable ${SAMPLE_OBJ}
was misspelled as ${SAMPLE_OBJS}.
Added prep makefile rule to make is easier to compile calc without
an optimizer. By doing:
make clobber prep
one may build a calc binary that is easier to debug.
Fixed a bug where an certain typos (e.g., calling an unknown
function) would previously cause calc to exit.
Updated the COPYING file to reflect the new filenames associated
with the SHA1 hash function, and removed mention of files related
to the SHA (SHA0, not SHA1) and the MD5 hash functions (which is
no longer supported in calc).
Fixed a bug where a calling vsnprintf() twice created problems.
The thanks for this fix goes to Matthew Miller (mattdm at mattdm
dot org) for this patch.
Michael Penk (mpenk at wuska dot com) reported success in installs
under windoz via Cygwin by making a change to the Cygwin target.
These changes have been folded into the main calc Makefile.
The old recommendation of using 'make win32_hsrc' is no longer
required for Cygwin. See the README.WINDOWS file for details.
Added dms.cal and hms.cal resource files. The dms.cal is a more
functional version of deg.cal. It is a superset except that increment
and decrement is on the arc second level. The hms.cal is for
24-hour cycle instead of the 360 degree cycle of dms.cal.
Changed deg.cal object name from dms to deg so that the more functional
dms.cal can own the dms object name.
Updated 'help obj' to reflect changes to 'show objfunctions' and
resource file example list since 1999.
Fixed problem where CALC_BYTE_ORDER referring to CALC_BIG_ENDIAN
and CALC_LITTLE_ENDIAN instead of BIG_ENDIAN and LITTLE_ENDIAN.
The following are the changes from calc version 2.12.3.0 to 2.12.3.3:
Fixed the Jacobi function where it returned 1 when it should have
returned 0. Thanks goes to Kevin Sopp (baraclese at googlemail dot com)
for discovering the problem and suggesting the nature if the fix.
Calc versions will always be of the form x.y.z.w even when the
MINOR_PATCH (w) is 0. Thus, 2.12.3.0 will be printed as 2.12.3.0
instead of just 2.12.3.
Added MINGW32_NT-5.0 compile target based on a patch from
Brian L. Angus (angus at eng dot utah dot edu).
Removed the use of rpm.release in the Makefile.
Mac OS Darwin targets no longer attempt to use ldconfig. Under the
Darwin target, the LDCONFIG make variable is redefined to be
an empty value. Thanks goes to Ralf Trinler (art at infra dot de)
for reporting this problem.
The ${CALC_INCDIR}/custom is no longer being removed at install time
if it is empty. Now when ${ALLOW_CUSTOM} make variable is empty,
an empty ${CALC_INCDIR}/custom may be left behind.
Fixed a problem where a "make clobber" would remove custom/Makefile
and fail to rebuilt it.
The following are the changes from calc version 2.12.2.3 to 2.12.2.4:
Added OpenBSD target.
Using the -r test instead of the -e test in Makefiles because some
out of date shells still do not have the -e test.
The Makefile now avoids the use of if ! command because some out of
date shells to not support the ! construct.
The following are the changes from calc version 2.12.1.1 to 2.12.2.2:
Added an explicit Solaris target.
Fixed confusion in Makefile where some uses of ${EXT} were misnamed ${EXE}.
Added a "make strip" rule, per suggestion from Igor Furlan <primorec
at sbcglobal dot net>, to allow one to strip previously built binary
executables and libraries.
Under the Darwin / OS X target, ${DARWIN_ARCH} is left empty meaning
that calc is compiled for the native CPU type instead of Universal
Binary (Intel and PPC).
By default, the calc binary that is built for the rpm forces
${LD_SHARE} to be empty. An empty ${LD_SHARE} means that the calc
from the rpm does not set rpath. This in turn causes the default
system path to be searched when looking for libcalc and libcustcalc.
The Makefile shipped with calc still sets ${LD_SHARE} for host targets.
By default, the dynamic shared library search path for all targets
starts with the source directory. Starting the search in the source
directory is convenient for testing and debugging but is not appropriate
for installation on a production system. To get the same effect
as the calc binary in the calc rpm, try:
make clobber
make calc-dynamic-only BLD_TYPE=calc-dynamic-only LD_SHARE=
make install
The libcalc and libcustcalc shared libraries are now tied to
the 4 level calc version instead of just 3 levels. For example,
under Linux calc version 2.12.2.1 uses /usr/lib/libcalc.so.2.12.2.1
instead of just the /usr/lib/libcalc.so.2.12.2 file. This change
was made so that calc produced by 'make clobber; make all install'
is consistent with the calc rpm.
Calc is now releasing the calc-debuginfo rpm for those RPM users who
which to use non-stripped libraries and binaries for debugging
purposes. By default, the calc rpm installed stripped binaries
and libraries.
Added this high priority item to the calc help/todo list:
It is overkill to have nearly everything wind up in libcalc.
Form a libcalcmath and a libcalclang so that an application
that just wants to link with the calc math libs can use them
without dragging in all of the other calc language, I/O,
and builtin functions.
Fixed the wording for the -i flag in the calc man page.
Added some notes to the help/unexpected file regarding calc
and interactive shells.
Fixed bug where a FILEPOS was copied FPOS_POS_BITS octets instead of
FPOS_POS_LEN octets.
Split out ${READLINE_EXTRAS} Makefile variables from ${READLINE_LIB}
to better deal with Fedora rpm requirements.
Bit 8 (0x80) of calc_debug is reserved for custom debugging.
See help/config and custom/HOW_TO_ADD for details.
When the Makefile variable ${ALLOW_CUSTOM} is not defined or empty,
the libcustcalc library is not built or linked against, certain make
rules skip going into the custom sub-directory, the install
rule skips certain custom installation actions, and the common
C flags (${COMMON_CFLAGS}) is given -UCUSTOM. Other make rules such
as "make clean" and "make clobber" still work as before. Also
the Makefile.simple assumes that the Makefile variable ${ALLOW_CUSTOM}
is -DCUSTOM.
Clarified that the calc builtin functions rand() and random()
operate over a half closed interval. The help/rand and help/random
refer to the top of the interval as "beyond" instead of "max".
Releasing source tar balls using bzip2 instead of with gzip. So
what was calc-something.tar.gz is now calc-something.tar.bz2.
To "uncompress" use:
bunzip2 calc-something.tar.bz2
On some systems, one may untar directly by:
tar -jxvf calc-something.tar.bz2
The Makefile variable ${BYTE_ORDER} was replaced by ${CALC_BYTE_ORDER}.
Changed the way the Makefile can force the calc byte order. If you set
the Makefile variable ${CALC_BYTE_ORDER} to be -DCALC_BIG_ENDIAN then
endian.h will force the CPP symbol CALC_BYTE_ORDER to be BIG_ENDIAN.
If you set ${CALC_BYTE_ORDER} to be -DCALC_LITTLE_ENDIAN then endian.h
will force the CPP symbol CALC_BYTE_ORDER to be LITTLE_ENDIAN.
If the Makefile variable ${CALC_BYTE_ORDER} is empty, then the CPP
symbol CALC_BYTE_ORDER will set to the CPP symbol BYTE_ORDER as
defined by some system include file (if the Makefile can find such
an include file), or the Makefile compiling endian.c and hopefully
using that result to set CPP symbol CALC_BYTE_ORDER. Regardless of
how it happens, the CPP symbol CALC_BYTE_ORDER should end up set in
endian_calc.h include file.
The following are the changes from calc version 2.12.1.10 to 2.12.2:
Put back the missing -s flags on the cscripts: mersenne, 4dsphere,
fprodcut, plus, and powerterm. Thanks goes to Bradley Reed
<bradreed1 at gmail dot com> for discovering this problem.
All static variables are now declared with the symbol STATIC.
All extern variables are now declared with the symbol EXTERN.
All static functions are now declared with the symbol S_FUNC.
All extern functions are now declared with the symbol E_FUNC.
The include file decl.h defines these 4 symbols by default
to static, extern, static, and extern respectively. Under
Windoz, DLL is also defined according to the _EXPORTING symbol
and is prepended to the EXTERN and E_FUNC symbols. The decl.h
file has replaced the win32dll.h file.
When WITH_TLS is defined, calc attempts to compile with Thread Local
Storage. As of version 2.12.1.12 this mode is extremely experimental.
Calc may not compile when WITH_TLS defined.
Fixed E_FUNC vs EXTERN issues discovered by Mirko Viviani
<mirko at objectlab dot org>.
Removed include of <malloc.h>. The building of the include file
"have_malloc.h" has been removed from the Makefile. One some
systems such as FreeBSD, the file /usr/include/malloc.h exists
and contains an forced error saying that stdlib.h should be used
instead. The Makefile symbol HAVE_MALLOC has been removed.
Moved the sample code in the sample sub-directory up into the
main source level. The sample/many_random.c source file is
now sample_many.c. The sample/test_random.c source file is now
sample_rand.c. The sample Makefile and the sub-directory is no more.
Renamed the following source files:
math_error.h ==> lib_calc.h
string.c ==> str.c
string.h ==> str.h
Renamed the following variables related to calc error processing:
int calc_jmp ==> int calc_use_matherr_jmpbuf
jmp_buf calc_jmp_buf ==> jmp_buf calc_matherr_jmpbuf
int post_init ==> int calc_use_scanerr_jmpbuf
jmp_buf jmpbuf ==> jmpbuf calc_scanerr_jmpbuf
char *calc_error ==> char calc_err_msg[MAXERROR+1]
These values are now declared in the lib_calc.h include file.
The value MAXERROR is now defined in lib_calc.h instead of calc.h.
The calc_err_msg[] buffer is now used for math errors as well
as scan and parse errors.
Parse/scan errors will not be printed if calc_print_scanerr_msg
is zero. By default:
int calc_print_scanerr_msg = 1;
This variable is declared in the lib_calc.h include file. Storage
comes from libcalc.
Parse/scan warnings will not be printed if calc_print_scanwarn_msg
is zero. By default:
int calc_print_scanwarn_msg = 1;
This variable is declared in the lib_calc.h include file. Storage
comes from libcalc.
The last parse/scan error message is stored in the calc_err_msg[]
buffer. This happens even when calc_print_scanerr_msg is zero.
The last parse/scan warning message is stored in the calc_warn_msg[]
buffer. After each parse/scan warning condition is detected,
the value calc_warn_cnt is incremented. This happens even when
calc_print_scanwarn_msg is zero.
The calc_warn_msg[] buffer and calc_warn_cnt variables are declared
in the lib_calc.h include file. Storage comes from libcalc.
See the file, LIBRARY or use the calc command "help libcalc" for
more information on calc error processing. This file has been
updated to reflect the changes noted above in this section.
The make install rule removes std_arg.h, have_malloc.h, math_error.h,
string.h, and win32dll.h from ${INCDIR} if they exist. These calc
include files are no longer supported.
Do reduce the number of special case .o build rules, the
${ALLOW_CUSTOM} make flag is added to ${CFLAGS} by default. This means
that if ALLOW_CUSTOM= -DCUSTOM, then -DCUSTOM is given to the compile
line of most .c files.
Calc -v reports "w/custom functions" or "w/o custom functions" on
the version string depending on if calc was compiled with the
ALLOW_CUSTOM= -DCUSTOM or not.
Replaced the concept of compiler sets in the Makefile with
host target section in the Makefile. Initial host targets are:
Linux
Darwin
FreeBSD
(default) <<== Target does not match any previous target name
Simple
NOTE: If your target is not supported below and the default target
is not suitable for your needs, please send to the:
calc-contrib at asthe dot com
Email address an "ifeq ($(target),YOUR_TARGET_NAME)"
... "endif" set of lines from the Makefile so that
we can consider them for the next release.
The custom/Makefile is now constructed from 3 parts: custom/Makefile.head,
the host target section in Makefile, and the custom/Makefile.tail.
The top level Makefile and the custom/Makefile require a GNU Make
(such as gmake) or an equivalently advanced make. On many targets,
the default make is sufficient. On FreeBSD for example, one must
use gmake instead of make.
