Sorry but it seams to me the question was answered a lot of time on the forum..
core gl context have dropped the standard fixed pipeline so in core context glsl you must define all your variable as old built-in (gl_XXX) have been removed. 
osg wraps them in osg_XXX but you may define your own vertex attribute array and use Program::addBindAttributeLocation to connect to your Shader
