I'm getting the same error with all GLFW3 demos on Arch. I've written programs using GLFW3 that work fine, so I'm pretty sure the issue lies in Nuklear.

glfw_opengl3 requires opengl 3.3, while you have only 2.1. What sample you are trying?

silversquirl commented 7 years ago

Hmmm... how odd, glxinfo shows 2.1 for me too. Is that a graphics card limitation? My system is up to date, so I don't think it's a software issue.

lieff commented 7 years ago

Yes, it's graphics card limitation, mesa supports minimum 3.1 for all included drivers: https://mesamatrix.net/ Proprietary drivers should support max hardware capabilities too.
