hi! i have been working on porting the build process in allegro (a game/multimedia library. see http://alleg.sourceforge.net for more info) to mingw32 and cygwin. and i have got almost everything finished now.
when building the mingw32 profiling version of the allegro library with cygwin using the following command line: dllwrap -mno-cygwin --target i386-mingw32 --def lib/mingw32/allegro.def -o lib/m ingw32/allp40.dll obj/mingw32/allp/allegro.o < --- snip (lots of object files) --- > ingw32/allp/wwnd.o obj/mingw32/allp/colconv.o obj/mingw32/allp/icolconv.o obj/mi ngw32/allp/pckeys.o -lkernel32 -luser32 -lgdi32 -lcomdlg32 -lole32 -ldinput -ldd raw -ldxguid -lwinmm -ldsound -lgmon -L/lib/mingw -lmoldname -lmsvcrt --outp ut-l ib lib/mingw32/liballp.a i get the following error: /usr/lib/libgmon.a(profil.o)(.text+0x127): undefined reference to `__errno' /usr/lib/libgmon.a(profil.o)(.text+0x171): undefined reference to `__errno' /usr/lib/libgmon.a(profil.o)(.text+0x1a1): undefined reference to `__errno' collect2: ld returned 1 exit status dllwrap: gcc exited with status 1 make.exe: *** [lib/mingw32/allp40.dll] Error 1 i have made sure to link only with the mingw32 runtime using -mno-cygwin. i have the latest cygwin packages installed including the mingw-runtime. i have also objdump'ed profil.o to see if it contained __errno, it contained ___errno... i guess it's the same. as a quick solution i have copied the file libgmon.a from the lib/ directory in the official mingw32 distribution and pasted it into /lib/mingw/ in my cygwin installation and it seemed to work. i'm not sure if the problem is the /lib/libgmon.a is dependant on parts of the cygwin runtime, but if that's the case whoever is the maintainer (christopher faylor i guess?) of the mingw-runtime package should include the mingw gmon library here.
