Hi @odidev,

I've added the [build wheel linux] tag into your PR title, so the CI can build linux wheels.
Feel free to add your optimisation commits, and let me know when you're ready for a review.
Would be nice to get it merged before Kivy 2.1.0 :)

Sadly, you can't edit the title to make it work, as explained here. You needed to originally open it with the build command in the title.

Yep, reminded it after triggering the re-run ☹️

But, new commits, made to this PR, should be able to trigger the build.

I'm not sure that the title will be changed though internally. I remember when testing it didn't work 😬

Uhm, I did it recently, multiple times and it worked.
But maybe I was making an improper use of a bug (When a bug is actually a feature 😂 ) .

@odidev Can you try to push a minor commit to see if the CI gives us a ✅ ?

Also, there's a specific reason to target ubuntu-18.04 ?

[matham]

I changed the ubuntu version and it did make the wheels! Although I didn't change it everywhere, although probably should.
