Ok, I tried that. I defined my var like so:
AM_CONDITIONAL(WIN, test "$PLATFORM" = "win")
AM_CONDITIONAL(UNIX, test "$PLATFORM" = "unix")
Then I put this in Makefile.am:
if WIN
sysinit = tkgsWinInit.c
endif
if UNIX
sysinit = tkgsUnixInit.c
endif
libtkgs_la_SOURCES = \
tkgs.c \
tkgs.h \
tkgsColor.c \
tkgsColor.h \
tkgsDrawable.c \
tkgsDrawable.h \
tkgsDriver.h \
tkgsFont.c \
tkgsInit.c \
tkgsInt.h \
tkgsObj.c \
tkgsObj.h \
tkgsUnixInit.c \
$(sysinit)
But I still get an error when I run automake.
src/Makefile.am:15: warning: automake does not support conditional
definition of sysinit in libtkgs_la_SOURCES
I am using the CVS versions of autoconf, automake, and libtool
(the ML branch).
