Hello,
I am trying to run the Pd patch
Gem/exemples/10.glsl/01.simple_texture.pd, but when i create the gemwin,
i get :
[glsl_fragment]: shader 'texture.frag' will be loaded when rendering is
turned on (openGL context needed)

OpenGL version is > 2.0 so GLSL program should run.
What can i do to run this simple shader
(Gem/exemples/10.glsl/01.simple_texture.pd) on UDOO ?
Any suggestion is welcome.
