Hi there,

thanks for your help ...

I made it simple, I played preprocessor ...
I looked in config.h, found that RETSIGTYPE was defined as void and replaced
the corresponding lines in fvwm/fvwm.h.
Now the line looks like "#define SIGNAL_RETURN return"

After that little change, I can run make ...

... but I get another error :

Compiling of FvwmBacker stops with an error about undefined symbols :

gcc -g -O2 -o FvwmBacker FvwmBacker.o root_bits.o -L../../libs
-L/usr/X11R6/lib -lfvwm -lXpm -lSM -lICE -lXext -lX11 -lm
ld: Undefined symbols:
_Pcmap
_Pdepth
_Pdpy
_Pvisual
make[3]: *** [FvwmBacker] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all-recursive-am] Error 2

What can I do here ?

(My goal is to write a little howto for compiling Fvwm 2.4.13 on Mac Os X
version 10.2.2 ...)
