Never mind.... I guess I found my answers here: http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.20.8.pdf

I send my shader programs through the C-Preprocessor (cpp) before giving them to OSG and CPP doesn't like this line (clearly it thinks its a command it should understand).. I assume this line is defining the Shader Version to use (1.2). If I don't have this line, the shader compiler doesn't like the "centroid" word. Setting OSG_NOTIFY_LEVEL seems to report that glslLanguageVersion=1.2 even when I don't use #version. Is there some other way to tell the shader compiler/OSG that that the shader is a 1.2 shader? While I'm at it, does the shader compiler natively support any CPP directives (i.e. # commands).?
