Hello, I've got problems with compiling gpc snapshot from 12.5 and latest cygwin with gcc 2.95.3-4 I did like described in the faq, and I had some problems I solved: -There was no patch for gcc 2.95.3-4 so I took the one for 2.95.3 -GPLUSPLUS_INCLUDE_DIR and TOOL_INCDLUDE_DIR wasn't declared in gpcpp.c, I found an #undeclare in cygwin.h and deletet it.
I am not sure that you should do that. I think you should trust that whoever undeclared it knew what they were doing. I normally can compile GPC for both Cygwin and Mingw without touching anything other than to apply the GPC patch.
So I looked into the cccp.c file which seems to be the c counterpart to gpcpp.c, here they did a #ifdef TOOL_INCLUDE_DIR around the critical parts, so I did the same for gpcpp.c and restored original cygwin.h. But this gives the same effect as before.
After that compiling worked, but if I use the compile now, the following appears: (gpc -v test.pas)
Do you have all the latest GNU tools and headers and libraries? You shouldn't have had to change cygwin.h to be able to build GPC successfully.
Yes, I used the setup utility from cygwin.com and installed experimental releases (gcc package isn't marked experimental anyway). I installed all the tools there.

GNU Pascal version 2.95.3-4 (cygwin special) (i586-pc-cygwin32) compiled by GNU C version 2.95.3-3 (cygwin special). GNU Pascal version is actually 20010512, based on gcc-2.95.3-4 (cygwin special) as -o /PlatteC/WINDOWS/TEMP/ccc85291 /PlatteC/WINDOWS/TEMP/ccb85291 gpc.exe: Internal compiler error in `do_spec_1', at p/gpc.c:4500
I have never seen this problem before. The GPC that you built is obviously broken. Why? I have no idea. Could it be a problem with your "specs" file? Perhaps Peter or Frank might have an idea what this error means.
I reinstalled everything, I did some tests, compiling works if I use the following sequence: gpc -c -o test.o test.pas gcc test.o -o test.exe -lgpc So It seems only an error reading the specs file, but I don't understand the spec file syntax :/. So I've attached it along with the changed gpcpp.c to this mail.
