GLSL compile failed (’GL_3DL_array_objects’ : extension is disabled or not available)

[Yuya_Fukazawa_bn7]

#version 310 es
precision highp float;
layout(location = 0) out vec4 Output;
void main()
{
	const float arr[3] = float[3]
	(
		0.0, 0.5, 1.0
	);
	Output = vec4( arr[0], arr[1], arr[2], 1.0 );
}

The above fragment shader compiles successfully with Intel® Graphics Driver 31.0.101.1692, but fails to compile with Intel® Graphics Driver 31.0.101.5333.

glGetShaderInfoLog returns "ERROR: 2668:38048.581: ’GL_3DL_array_objects’ : extension is disabled or not available".

I think this compile error is a bug in the driver.

I have attached some files.

・Report/GLSLCompilerTest/bin/GLSLCompilerTest.exe is the executable file that compiles the above fragment shader.

・Report/CompileSucceeded_30.0.101.1692.png is an image of a successful compilation with Intel® Graphics Driver 30.0.101.1692.

・Report/CompileFailed_30.0.101.5333.png is an image of failed compilation with Intel® Graphics Driver 31.0.101.5333.

Isn't this incorrect?

OpenGL 4.5 contains GL_ARB_ES3_1_compatibility.

Do you have any official documentation where this is disclaimed? It could help me to push the issue to the right way.

Using the core profile context (GLSLCompilerTest.exe), the shader compilation fails.

But, using the (GLSLCompilerTest.exe -compat), the shader compiles successfully.

Is this the behavior to expect?

I need to check it with the team.

Hello @Arturo_Intel 

Is there any progress on this issue?

[Arturo_Intel · Accepted solution]

Hello Fukazawa-san:

Please try the 101.6332 driver version (Intel® Arc™ & Iris® Xe Graphics - Windows*)

The missing support of the OpenGL extension was added
