libglut is missing library for MinGW static linking




libglut-devel provides libglut.a and libglut.dll.a but linking libglut.a with either "-lglut" or "-lglut.dll" both depend on either cygglut-3.dll or libglut-0.dll respectively when compiling for Cygwin or MinGW.

I understand that this isn't a big deal for Cygwin binaries as it's not possible to statically link those executables anyways. But glut has the ability to link statically and this is of benefit on Windows with MinGW for convenience and ease of distribution.

To perform static linking against glut, I have to download "libfreeglut_static.a" as provided by http://freeglut.sourceforge.net. I can still use libglut but the static library provides the missing dependencies to mitigate the need for the shared library.

I can compile as such:

i686-w64-mingw32-g++.exe -DFREEGLUT_STATIC main.cpp -lglut -lfreeglut_static -lgdi32 -lwinmm -lglu32 -lopengl32 -L. -oa.out

The resulting executable is completely static and stand-alone and does not require a shared library. The key here is the define "FREEGLUT_STATIC" along with libfreeglut_static provided from the freeglut website.

I don't know what Cygwin's policy is on providing static libraries for MinGW but this is a very good candidate as it already has all of the necessary declarations defined.
