GLSL compiler error on Linux

[zicklag]

I am using Krom on Ubuntu 16.04 and get the following errors running any Armory example. There is a built example that you can test here.

GLSL compiler error: 0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, 3.00 ES, 3.10 ES, and 3.20 ES

GLSL compiler error: 0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, 3.00 ES, 3.10 ES, and 3.20 ES

GLSL linker error: error: linking with uncompiled shadererror: linking with uncompiled shader

The output from glxinfo | grep OpenGL:

OpenGL vendor string: X.Org
OpenGL renderer string: AMD MULLINS (DRM 2.50.0 / 4.13.0-32-lowlatency, LLVM 5.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.8
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 17.2.8
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 17.2.8
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10
OpenGL ES profile extensions:

As far as I understand it, the line, OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.8, means that my system should work with OpenGL up to version 4.5, but the error message is saying that GLSL 3.30 is not supported.

I found a similar issue on Stack Overflow that makes it sound like this might have something to do with Krom not requesting a Core Profile, but I don't really know much about this so I wouldn't know.

If this is too specific as it has to do with Armory games, you can close the issue. I have an open issue on the Armory project, armory3d/armory#500, but I think the issue might actually be Krom. Any help at all is appreciated. :slightly_smiling_face:

I'm getting this, too, with every file I've tried including the default blender cube, playground and the Armory benchmark. My card is pretty old. I've tried changing the Render Path to medium.

In response to my original issue @luboslenco created a patch for armory that provides a temporary work around to use older shader versions ( see the comment ). It's a "Legacy Shaders" checkbox on the addon settings page. I'm not sure how many different things could break graphically by using it though.

If your issue is similar to mine, it will also probably work fine in the browser ( though the browser is going to run slower than Krom ) if that is any help.

With "Legacy Shaders" option enabled the voxel ao/gi stuff will not work but apart from that it should do. And also investigating the "Krom not requesting a Core Profile" now.:)

Krom/Kore should request core-profile now (also included in the latest armory builds).

That's AWESOME! I can't wait to try it. :tada:

IT WORKED!! Thank you for the fix. I just can't believe how amazing Armory is. Now I can use it to its full potential. Thanks a lot!
