CFITSIO Interface Library CFITSIO is a library of ANSI C routines for reading and writing FITS format data files. A set of Fortran-callable wrapper routines are also included for the convenience of Fortran programmers. This README file gives a brief summary of how to build and test CFITSIO, but the CFITSIO User's Guide, found in the files cfitsio.doc (plain text), cfitsio.tex (LaTeX source file), cfitsio.ps, or cfitsio.pdf should be referenced for the latest and most complete information. BUILDING CFITSIO ---------------- The CFITSIO code is contained in about 40 *.c source files and several *.h header files. The CFITSIO library is built on Unix systems by typing: > ./configure [--prefix=/target/installation/path] > make (or 'make shared') > make install (this step is optional) at the operating system prompt. The configure command customizes the Makefile for the particular system, then the `make' command compiles the source files and builds the library. Type `./configure' and not simply `configure' to ensure that the configure script in the current directory is run and not some other system-wide configure script. The optional 'prefix' argument to configure gives the path to the directory where the CFITSIO library and include files should be installed via the later 'make install' command. For example, > ./configure --prefix=/usr1/local will cause the 'make install' command to copy the CFITSIO libcfitsio file to /usr1/local/lib and the necessary include files to /usr1/local/include (assuming of course that the process has permission to write to these directories). On VAX/VMS and ALPHA/VMS systems the make.com command file may be used to build the cfitsio.olb object library using the default G-floating point option for double variables. The make\_dfloat.com and make\_ieee.com files may be used instead to build the library with the other floating point options. A precompiled DLL version of CFITSIO is available for IBM-PC users of the Borland or Microsoft Visual C++ compilers in the files cfitsiodll_xxxx_borland.zip and cfitsiodll_xxxx_vcc.zip, where 'xxxx' represents the current release number. These zip archives also contains other files and instructions on how to use the CFITSIO DLL library. The CFITSIO library may also be built from the source code using the makefile.bc or makefile.vcc files. Finally, the makepc.bat file gives an example of building CFITSIO with the Borland C++ v4.5 compiler using simpler DOS commands. When building on Mac OS-X, users should follow the Unix instructions, above. Previous MacOS versions of the cfitsio library can be built by (1) un binhex and unstuff cfitsio_mac.sit.hqx, (2) put CFitsioPPC.mcp in the cfitsio directory, and (3) load CFitsioPPC.mcp into CodeWarrior Pro 5 and make. This builds the cfitsio library for PPC. There are also targets for both the test program and the speed test program. To use the MacOS port you can add Cfitsio PPC.lib to your Codewarrior Pro 5 project. Note that this only has been tested for the PPC and probably won't work on 68k macs. TESTING CFITSIO --------------- The CFITSIO library should be tested by building and running the testprog.c program that is included with the release. On Unix systems, type: - % make testprog % testprog > testprog.lis % diff testprog.lis testprog.out % cmp testprog.fit testprog.std - On VMS systems, (assuming cc is the name of the C compiler command), type: - $ cc testprog.c $ link testprog, cfitsio/lib $ run testprog - The testprog program should produce a FITS file called `testprog.fit' that is identical to the testprog.std FITS file included in this release. The diagnostic messages (which were piped to the file testprog.lis in the Unix example) should be identical to the listing contained in the file testprog.out. The 'diff' and 'cmp' commands shown above should not report any differences in the files. USING CFITSIO ------------- The CFITSIO User's Guide, contained in the files cfitsio.doc (plain text file) and cfitsio.ps (postscript file), provides detailed documentation about how to build and use the CFITSIO library. It contains a description of every user-callable routine in the CFITSIO interface. The cookbook.c file provides some sample routines for performing common operations on various types of FITS files. Programmers are urged to examine these routines for recommended programming practices when using CFITSIO. Users are free to copy or modify these routines for their own purposes. SUPPORTED PLATFORMS ------------------- CFITSIO has currently been tested on the following platforms (not up-to-date): Operating System Compiler ---------------- -------- OPERATING SYSTEM COMPILER Sun OS gcc and cc (3.0.1) Sun Solaris gcc and cc Silicon Graphics IRIX gcc and cc Silicon Graphics IRIX64 MIPS Dec Alpha OSF/1 gcc and cc DECstation Ultrix gcc Dec Alpha OpenVMS cc DEC VAX/VMS gcc and cc HP-UX gcc IBM AIX gcc Linux gcc MkLinux DR3 Windows 95/98/NT Borland C++ V4.5 Windows 95/98/NT/ME/XP Microsoft/Compaq Visual C++ v5.0, v6.0 Windows 95/98/NT Cygwin gcc OS/2 gcc + EMX Mac OS 7.1 or greater Metrowerks 10.+ Mac OS-X 10.1 or greater cc (gcc) CFITSIO will probably run on most other Unix platforms without modification. Cray supercomputers computers are currently not supported. Reports of any success or failure to run CFITSIO on other platforms would be appreciated. Any problem reports or suggestions for improvements are also welcome and should be sent to the HEASARC. ------------------------------------------------------------------------- William D.
