So i tried to began with the example provided on cygnus.com , it works fine, i got my foo.dll, main.exe, but moving to my real software when I run ld I got: c:/gnuwin32/b18/H-i386-cygwin32/i386-cygwin32/lib/libcygwin.a(libccrt0.o)(.t ext+0x8a):libccrt0.cc: undefined reference to `GetModuleHandleA@4' c:/gnuwin32/b18/H-i386-cygwin32/i386-cygwin32/lib/libcygwin.a(libcmain.o)(.t ext+0xc):libcmain.cc: undefined reference to `GetModuleHandleA@4' c:/gnuwin32/b18/H-i386-cygwin32/i386-cygwin32/lib/libcygwin.a(libcmain.o)(.t ext+0x15):libcmain.cc: undefined reference to `GetCommandLineA@0' c:/gnuwin32/b18/H-i386-cygwin32/i386-cygwin32/lib/libcygwin.a(libcmain.o)(.t ext+0x1e):libcmain.cc: undefined reference to `WinMain@16' This seems to be a reentrancy problem, since a simple call like : fprintf(stderr, ...) makes use of _impure_ptr which is a struct _reent* ptr that is provided by any process using the dll. So , probably the exact question is : how to say to ld: this symbol must not be search in libc, (libccrto.o, libcmain.o) but must be mapped to a symbol defined in the calling process? Any idea?
