not clear to me what are you trying to do
I'm trying to compile an X11 application with mingw (to run it on Windows).
Lets look at the attached minimal example gui.c (it's from the first
answer on [1] in case attachments are not allowed on the list):
- cygwin with standard cygwin X11 libs works:
gcc gui.c -lX11
./a.exe # -> fine
- mingw with XportMinGW X11 libs [2] works:
i686-w64-mingw32-gcc gui.c -I include -L lib -lX11 -lXau -lws2_32
./a.exe # -> fine
- mingw with cygwin ports X11 libs doesn't work:
i686-w64-mingw32-gcc gui.c -lX11
./a.exe # -> segfaults or exits with code 127
Am I doing something wrong or is this not supported?
Thanks!
