So, the notify thing is working now. I get the info logs when compiling, but everything seems to be fine. The glProgram links correctly, just some casting warnings. I really don't know why it fails. Could there be a problem with the gl_TextureMatrix[1] in the vertex program? What I want is simply to transfer the gl_TexCoords of my shadowMap to the frag program. I am still thankful for every hint.
