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. After that compiling worked, but if I use the compile now, the following appears: (gpc -v test.pas) Reading specs from /usr/lib/gcc-lib/i586-pc-cygwin32/2.95.3-4/specs gpc version 20010512, based on 2.95.3-4 (cygwin special) /usr/lib/gcc-lib/i586-pc-cygwin32/2.95.3-4/gpcpp.exe -lang-pascal -v -famtmpfile=/PlatteC/WINDOWS/TEMP/cc985291 -fdelphi-comments -D__GNU_PASCAL__ -undef -D__GNUC__=2 -D__GNUC_MINOR__=95 -D__GPC__=2 -D__GPC_MINOR__=0 -D__GPC_RELEASE__=20010512 -D__BITS_LITTLE_ENDIAN__=1 -D__BYTES_LITTLE_ENDIAN__=1 -D__WORDS_LITTLE_ENDIAN__=1 -D_X86_=1 -D_X86_=1 -Asystem(winnt) -Acpu(i386) -Amachine(i386) -Di386 -D__i386 -D__i386__ -Di586 -Dpentium -D__i586 -D__i586__ -D__pentium -D__pentium__ -D__stdcall=__attribute__((__stdcall__)) -D__cdecl=__attribute__((__cdecl__)) -D_stdcall=__attribute__((__stdcall__)) -D_cdecl=__attribute__((__cdecl__)) -D__declspec(x)=__attribute__((x)) -D__CYGWIN32__ -D__CYGWIN__ -Dunix -D__unix__ -D__unix -isystem /usr/local/include -idirafter /usr/include -idirafter /usr/include/w32api test.pas /PlatteC/WINDOWS/TEMP/cca85291 GNU Pascal Compiler PreProcessor version 20010512, based on gcc-2.95.3-4 (cygwin special) (80386, BSD syntax) #include "..." search starts here: #include <...> search starts here: /usr/local/include /usr/local/include /include /usr/lib/gcc-lib/i586-pc-cygwin32/2.95.3-4/include /usr/include /usr/include /usr/include/w32api End of search list. /usr/lib/gcc-lib/i586-pc-cygwin32/2.95.3-4/gpc1.exe /PlatteC/WINDOWS/TEMP/cca85291 -quiet -dumpbase test.pas -version -famtmpfile=/PlatteC/WINDOWS/TEMP/cc985291 -o /PlatteC/WINDOWS/TEMP/ccb85291 GNU Pascal version 2.95.3-4 (cygwin special) (i586-pc-cygwin32) compiled by GNU C version 2.95.3-3 (cygwin special).
