<pre>I am the sso5 branch at commit 82f823ec58210fa522c8f65a954acd720471a7da running
on Intel Sandy Bridge.
The problem is that when using #version 140 (the highest version supported by
SNB) and enabling #extension GL_ARB_separate_shader_objects : enable I get the
following error from glsl_compiler:
0:7(1): error: #version 150 required for using interface blocks
This can be repro'd with the following shader:
#version 140
#extension GL_ARB_explicit_attrib_location : enable
#extension GL_ARB_separate_shader_objects : enable
layout(location = 0) in vec4 inPos;
layout(location = 1) in vec2 inTexCoords;
layout(location = 0) out vec4 texCoords;
out gl_PerVertex
{
vec4 gl_Position;
};
void main()
{
texCoords = vec4( inTexCoords, 0.0, 0.0 );
gl_Position = inPos;
}
I have fixed this bug locally. A diff of the fix follows.
