Summary: osmesa: Expose GL entry points for Windows build, via
.def file
Product: Mesa
Version: 11.0
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: medium
Component: Mesa core

git format-patch
As the GLEW maintainer, I've been looking to support OSMesa natively in GLEW,
when built in -DGLEW_OSMESA=1 mode. I had some success with on Linux, but
linking with libOSMesa, rather than libGL. However, the Windows scons build
does not export the OpenGL functions that GLEW needs, such as glGetString.
Linux:
$ nm -D /usr/lib/x86_64-linux-gnu/libOSMesa.so | grep glGetString
000000000026e620 T glGetString
0000000000270d40 T glGetStringi
I found that GLEW utilities glewinfo and visualinfo work on Windows with
OSMesa, given a patched osmesa.def, as attached.
