This is Parrot, version 0.4.0

PREREQUISITES
-------------
You'll need a C compiler, a linker and a make program of course. If you
will be linking with the ICU library you have to download and install it
before configuring Parrot.
Get it from http://www-306.ibm.com/software/globalization/icu/downloads.jsp
You'll also need Perl 5.6 or above to run various configure and
build scripts.
For most of the platforms that we are supporting initially,
Parrot should build out of the box.
The list of targeted platforms can be found in PLATFORMS.
The current configure system is primitive, as it's only
a temporary solution. It will be happy with most any answers
you decide to feed it. Garbage In, Garbage Out.
INSTRUCTIONS
------------
For now, unpack your Parrot tarball, (if you're reading this, you've
probably already done that) and type
perl Configure.pl
to run the Configure script. The Configure.pl script extracts
configuration from the running perl5 program. Unfortunately, the perl5
configuration is not set up to compile and link c++ programs, so you
may need to explicitly tell Configure.pl which compiler and linker to
use. For example, to compile C files with 'cc', C++ files with
'CC', and link everything together with 'CC', you would type
perl Configure.pl --cc=cc --cxx=CC --link=CC --ld=CC
See "perl Configure.pl --help" for more options.
For systems like HPUX that don't have inet_pton please run
perl Configure.pl --define=inet_aton
If you want to install Parrot into a non-standard location use
perl Configure.pl --prefix=/Users/foo/parrot-0.4.0
Running Configure.pl will generate a config.h header, a Parrot::Config
module, platform files and some Makefiles.
The file "myconfig" has an overview of configure settings.
Next, run make:
For UNIX like systems that come with its own make, 'gmake' should be
used. (On most Linux systems, this is the default make.)
On windows systems, 'nmake' is used
On other systems, just try 'make'
Now, the interpreter should build. If you are building the ICU library
(this is the default on most systems), you need to use GNU make instead
(or something compatible with it).
You can test parrot by running
make test (or nmake test or gmake test)
You can run the full test suite with
make fulltest
Note: PLATFORMS contains notes about whether test failures are expected
on your system.
On some systems you can install parrot:
make install
This installs a bunch of files in /usr/local/parrot-$VERSION. The parrot
executable is in /usr/local/parrot-$VERSION/bin. Please note that this
feature is currently experimental. You have to link or copy the executable
somewhere into your path. Finally no dynamic extensions from
runtime/parrot/dynext are installed, albeit dynamic extensions are searched
for in the installed directory structure.
Look at docs/parrot.pod and docs/intro.pod for where to go from here. If you
have any problems, see the section "Reporting Problems" in docs/intro.pod.
These documents are in POD format. You can view these files with:
perldoc -F docs/intro.pod
NOTES
-----
On some older computers with little RAM, the computed-goto dispatch core
(ops/core_ops_cg.c) may take a while to compile or may fail to compile at all.
You can pass a flag to Configure.pl (--cgoto=0) to disable the computed-goto
core, at a slight cost in runtime speed.
CHANGES
-------
For documentation on the user-visible changes between this version and
previous versions, please see NEWS.
KNOWN ISSUES
------------
Some PASM examples are currently broken. The docs/BROKEN file lists other
major subsystems and regressions that block progress.
