[osg-users] GLSL plugin static linking issue (recent master branch)

[Voerman, L.]

Hi Andrew,
the options should not influence the library loading, it's the datafiles
that can be cached.
I'm just guessing here, but are you trying to load a file named
"filename.glsl"? that would match the problem you see.
the glsl plugin is strange in that it does not support *.glsl files.
rename your datafile .vert , .frag or .geom as appropriate for the type of
shader it contains.
Laurens.
