[SOLVED] SDL based build issue on linux (3d3ae83)

Updated to HEAD tonight.
Built just fine on my specific Arch install.
But when trying on Ubuntu… I ran into some issues.

Went back and checked the docs… and tried to thouroughly go through the requirements on linux (Which looks like the list has gotten a bit longer and a little more diffucult to parse).
My bases are covered in that area, I think.
Still however, after looking at the libs, and just starting from a fresh clone, kept getting road blocked at the same place.

Is there something obvious that I am missing?

Looks like SDL issue with MIR. Can you try and change it to Wayland or X11?

Makes sense.
The docs say this:

Which says that x11 takes precedence. But maybe i am not understanding this right either. Because it goes on t say you can override it at runtime.
But I am dealing with build time. And I didnt see a urho3d_* flag to specify not building with mir.

So there in lies my confusion. Not sure how to “change it to X11”.

I had the same issue: https://github.com/urho3d/Urho3D/issues/1685

Solved

That was it.
