OS/2 Installation Notes for FFTW 1.x

The following instructions are obsolete. Newer versions of FFTW use a configuration script to automatically create the Makefile; this script probably only works on Unix-like systems, however. So, you will need to create your own Makefile, or whatever your development system requires; see the section of the FFTW manual describing installation on non-Unix systems. Please let us know what your experiences are in installing FFTW on OS/2.

Chris Lanciani successfully installed FFTW 1.2 on his OS/2 Warp 4 system (using gcc 2.7.2), and has told us that the following changes were necessary:

• changed "prefix" line to prefix = \unix\emx
• changed forward slashes to backslashes in the "LIBDIR" and "INCLUDEDIR" lines
• changed the "RM" line to RM = del
• changed the "CP" line to CP = copy
• used the RANLIB = echo ranlib line
• in testnd.c, changed the "USE_RANDOM" #define to #define USE_RANDOM 0 since his system doesn't have the random() function.
