I've followed the instructions given by Mumit Khan : * got egcs-1.1.1-mingw-libs.tar.gz * installed the target libraries in /usr/local/mingw-libs * add -mno-cygwin to gcc -c * add -L/usr/local/mingw-libs to gcc -o It works well with the small hello.c program (thanks Mumit, the tutorial is clear and well done) I'm also using wxWindows 2.0 and i've some troubles while linking some samples. For example, I want to run the "minimal" sample and I get some "undefined reference ": __________________________________________________________________ gcc -c -D_X86_=1 -DWIN32 -D_WIN32 -DWINVER=0x0400 -D__WIN95__ -D__GNUWIN32__ -D__WIN32__ -I/wx/include -I/wx/src/png -I/wx/include/wx/msw/gnuwin32 -I/wx/src/zlib -D__EGCS__ -mno-cygwin -D__WXMSW__ -D__WINDOWS__ -ggdb -D__WXDEBUG__ -Wall -o minimal.o minimal.cpp windres.exe -i minimal.rc -o minimal_resources.o --include-dir /wx/include --define __WIN32__ --define __WIN95__ --define __GNUWIN32__ gcc -Wl,--subsystem,windows -mwindows -L/usr/local/mingw-libs -L/wx/lib -o minimal.exe minimal.o minimal_resources.o /wx/lib/libwx.a -lstdc++ -lgcc -lwinspool -lwinmm -lshell32 -lcomctl32 -lctl3d32 -lodbc32 -ladvapi32 -loldnames /cygnus/CYGWIN~1/H-I586~1/i586-cygwin32/bin/ld: warning: cannot find entry symbol _WinMainCRTStartup; defaulting to 00401000 /wx/lib/libwx.a(textctrl.o): In function `wxTextCtrl::GLOBAL_$I$GetClassInfo(void) const': /wx/src/msw/textctrl.cpp:71: undefined reference to `streambuf::xsputn(char const *, long)' /wx/src/msw/textctrl.cpp:71: undefined reference to `streambuf::xsgetn(char *, long)' /wx/src/msw/textctrl.cpp:71: undefined reference to `streambuf::sys_read(char *, long)' /wx/src/msw/textctrl.cpp:71: undefined reference to `streambuf::sys_write(char const *, long)' /usr/local/mingw-libs/libstdc++.a(iostream.o)(.text+0x18a9): undefined reference to `__imp__iob' /usr/local/mingw-libs/libstdc++.a(iostream.o)(.text+0x18b7): undefined reference to `__imp__iob' /usr/local/mingw-libs/libstdc++.a(streambuf.o)(.text+0x30c): undefined reference to `_errno' /usr/local/mingw-libs/libstdc++.a(stdstrbufs.o)(.text+0x2d): undefined reference to `__imp__iob' /usr/local/mingw-libs/libstdc++.a(fileops.o)(.text+0x173): undefined reference to `_errno' /usr/local/mingw-libs/libstdc++.a(fileops.o)(.text+0x1de): undefined reference to `_errno' /usr/local/mingw-libs/libstdc++.a(fileops.o)(.text+0x232): undefined reference to `_errno' /usr/local/mingw-libs/libstdc++.a(fileops.o)(.text+0x343): undefined reference to `_errno' /usr/local/mingw-libs/libstdc++.a(fileops.o)(.text+0x3f6): undefined reference to `_errno' /usr/local/mingw-libs/libstdc++.a(fileops.o)(.text+0x539): more undefined references to `_errno' follow /usr/local/mingw-libs/libstdc++.a(floatconv.o)(.text+0x12e7): undefined reference to `__imp__HUGE_dll' /usr/local/mingw-libs/libstdc++.a(floatconv.o)(.text+0x145a): undefined reference to `_errno' collect2: ld returned 1 exit status make: *** [minimal.exe] Error 1 __________________________________________________________________ So, my question is : Am I doing something wrong or should is it impossible to make cross-compilation with wxWindows tools ?
