Hello,
my shader compile stage throws out such warnings:
0(8) : warning C7532: global type sampler2DRect requires "#version 140"
or later
0(8) : warning C0000: ... or #extension GL_ARB_texture_rectangle : enable
and Then I add
#version 140
#extension GL_ARB_texture_rectangle : enable
at the very head of the shader file, but the warnings remain.
So how can I check whether my programm is able to use
#version 140
#extension GL_ARB_texture_rectangle : enable
?
Thank you very much in advance.
