Hi,

In EXT_texture_rg.txt it is mentioned of GL_RED_EXT on gles 2.0.

In  glformats.c::_mesa_es_error_check_format_and_type returns 
GL_INVALID_VALUE if  GL_RED_EXT(as it reaches default case)

so glTexImage2D(..., GL_RED_EXT, GL_UNSIGNED_BYTE, data) fails.

Though GL_EXTENSIONS contains GL_EXT_texture_rg.

So it seems that GL_RED_EXT is actually only possible with gles >= 3.0.

What am I missing ?



Which version of Mesa are you using to test this? Ilia fixed this bug:

https://bugs.freedesktop.org/show_bug.cgi?id=93126

which I believe should fix this issue, fix is available in current 
master and Mesa 11.1.




Thx in advance for any clarification.
Julien

Hi,

maybe it's a similar issue as
https://bugs.freedesktop.org/show_bug.cgi?id=92265
perhaps?


Thanks,
