New mingw32 packages are always welcome! I don't know if you're already
familiar with maintaining regular RPMs for Fedora, but we tried to keep
the packaging of mingw32 packages as easy as possible. In order to port
a native Fedora package to a mingw32 package, there are some steps which
need to be done:
- Calls to the macro %configure need to be replaced with
%{_mingw32_configure}.
- File lists will need to be updated to use macro's like
%{_mingw32_bindir} and %{_mingw32_libdir} instead of %{_bindir} and
%{_libdir}
- The package needs to be made noarch, so a 'BuildArch: noarch' needs to
be added
- Some mingw32 specific BuildRequires need to be added. At least ones
should be added for mingw32-filesystem, mingw32-gcc and
mingw32-binutils. Depending on the dependencies of the package itself
more mingw32-specific BR's might be needed
- The top of the .spec file should begin with these set of macro's:
%global __strip %{_mingw32_strip}
%global __objdump %{_mingw32_objdump}
%global _use_internal_dependency_generator 0
%global __find_requires %{_mingw32_findrequires}
%global __find_provides %{_mingw32_findprovides}
When putting a new package up for review, don't forget to CC
[email protected] so that you have a better chance
that somebody reviews the package soon.

The '-mwindows' compiler flag is used to indicate that the resulting
executable shouldn't show a console window when it's started. When the
compiler flag '-mconsole' is used a console window will be shown where
all stdout/stderr-output gets shown.
Applying a change in the configure.ac file which adds a special check
for mingw32 environments seems like the correct approach to me.
I don't know if the Windows opengl32 library contains all the OpenGL
functions you want to use, but there's also a mingw32-freeglut package
in the Fedora repositories which offers additional OpenGL functions.
If you've got any more questions, feel free to drop them on this list
Kind regards,
Erik van Pienbroek
