I have tried compiling it under FC2 and it didn't work straight out of the package.
this is what I got: [EMAIL PROTECTED] ctwm]$ xmkmf mv -f Makefile Makefile.bak imake -DUseInstalled -I/usr/X11R6/lib/X11/config <stdin>:1:19: stdio.h: No such file or directory <stdin>:2:19: ctype.h: No such file or directory <stdin>: In function `main': <stdin>:18: error: `NULL' undeclared (first use in this function) <stdin>:18: error: (Each undeclared identifier is reported only once <stdin>:18: error: for each function it appears in.) /usr/X11R6/bin/xmkmf: line 70: 8081 Aborted imake $imake_defines $args [EMAIL PROTECTED] ctwm]$
Hmm... worked for me. It looks very suspicious that stdio.h and ctype.h could not be found. I suspect that you are missing the glibc-headers RPM.
