To work around these errors you might try to define NO_TEXT_WINDOW_STREAM for wxWindows compilation. > /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 No idea about these. > So, my question is : > Am I doing something wrong or should is it impossible to make > cross-compilation with wxWindows tools ? There is no reason it shouldn't be possible. It would be interesting to hear whether you succeed with it finally and what had you to change to do it. Good luck!
