Shader Loading Problem

advanced
#1

Hi, i’m trying to use billboard technique to draw a texture on a mesh.
I am experencing this problem when i use the billboard shader as in the billboardExample:

[error] OpenGL generated error 1282 trying to get the compile status for GL_VERTEX_SHADER shader. Does your video card support this?

[warning] ofShader: releasing program not found, this shouldn’t be happening releasing anyway

Basically i just copied the shaders used in the Billboardexample (both files .frag and .vert) in my data folder and in the application i make an object of type ofShader. When i call shader.load(“Billboard”) i have the error.

I can’t really figure out where the problem is…

Any help would be appreciated.

I’m also getting this problem (on a late 2011 macbook pro) when trying to load a shader. Did you find a solution?
