[GEM-dev] Problem with GLSL on UDOO

[Jack]

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)
[pix_texture]: using mode 0: TEXTURE_2D

If i send [print( to [glsl_fragment] i get :

If i send [print( to [gemwin] i get :

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.
