android shader link error

[mikefalk]

On android 4.0 when I add any compositor I get only black screen and a log message like this:

Code: Select all

 Vertex Program:Ogre/Compositor/StdQuad_GLSLES_vp Fragment Program:Ogre/Compositor/B&W_GLSLES_FP
        GLSL link result :
        P1202: Texture's gl states do not match with shader's

This error is tegra specific one i guess can you add more infor which device which gpu?

[mikefalk]

acer iconia tab - tegra 2, samsung galaxy tab - tegra 2, asus eee pad - tegra 3

I can't found the reason of the message, but I found the topic with similar problem. Render system can't draw the texture on the screen quad because of string "filtering linear linear linear" in compositor's material. When I changed it to "filtering linear linear none" the compositor started to work.

i know this thread is old, but for the next readers,
the problem seems about the texture format bound in fragment shaders, ex on tegra this will fail and generate this error if the texture is format PF_B8G8R8A8
and problem will disappear if texture is : PF_A8R8G8B8.
