It would appear when one doesn’t have a graphical card drivers capable of hardware-accelerated OpenGL. Perhaps you’re using Wayland or something?..

Okay, could you please run this build and after it shows error message, post the file /tmp/allegro.log from your system? Thanks!
Thank you!
Judging by the log and liballegro code, it would appear that your video card is just not capable enough. Allegro requires the following list of things: OpenGL rendering, RGBA colors, double buffering, stereo buffers (whatever those are), auxiliary color buffers, depth buffer, stencil buffer, and accumulation buffer.
I’m sorry it doesn’t work for you 😔
