Hi Folks, My apologies if this is a silly question... I've just compiled gpc-20020510 on my Red Hat 9 system and I can't seem to compile any of the demo programs (except hello.pas). Here is what I did mv gpc-20020510/p/ gcc-2.95.2/gcc/ mkdir gpc-build cd gpc-build ../gcc-2.95.2/configure --enable-language=pascal --prefix=/home/leo/local make install There were no errors during the above compilation. Next I tried the demo programs, cd ~/local/doc/gpc/demos gpc factorial.pas factorial.pas:31: module/unit interface `Gpc' could not be imported I guess there is something blindingly obvious that I have forgotten. Can anyone enlighten me please? Thanks, Leo Brewin
