fftw3: Installation on non-Unix systems
10.2 Installation on non-Unix systems
=====================================
It should be relatively straightforward to compile FFTW even on non-Unix
systems lacking the niceties of a 'configure' script. Basically, you
need to edit the 'config.h' header (copy it from 'config.h.in') to
'#define' the various options and compiler characteristics, and then
compile all the '.c' files in the relevant directories.
The 'config.h' header contains about 100 options to set, each one
initially an '#undef', each documented with a comment, and most of them
fairly obvious. For most of the options, you should simply '#define'
them to '1' if they are applicable, although a few options require a
particular value (e.g. 'SIZEOF_LONG_LONG' should be defined to the size
of the 'long long' type, in bytes, or zero if it is not supported). We
will likely post some sample 'config.h' files for various operating
systems and compilers for you to use (at least as a starting point).
Please let us know if you have to hand-create a configuration file
(and/or a pre-compiled binary) that you want to share.
To create the FFTW library, you will then need to compile all of the
'.c' files in the 'kernel', 'dft', 'dft/scalar', 'dft/scalar/codelets',
'rdft', 'rdft/scalar', 'rdft/scalar/r2cf', 'rdft/scalar/r2cb',
'rdft/scalar/r2r', 'reodft', and 'api' directories. If you are
compiling with SIMD support (e.g. you defined 'HAVE_SSE2' in
'config.h'), then you also need to compile the '.c' files in the
'simd-support', '{dft,rdft}/simd', '{dft,rdft}/simd/*' directories.
Once these files are all compiled, link them into a library, or a
shared library, or directly into your program.
To compile the FFTW test program, additionally compile the code in
the 'libbench2/' directory, and link it into a library. Then compile
the code in the 'tests/' directory and link it to the 'libbench2' and
FFTW libraries. To compile the 'fftw-wisdom' (command-line) tool (
Wisdom Utilities), compile 'tools/fftw-wisdom.c' and link it to the
'libbench2' and FFTW libraries
