hello, i am sorry(I am only begener) but I was trying this library on linux arm(andronix, you can see on Linux Distro on Android) and I found this:
- build with sdl2:
./sdl2
shared memfd open() failed: Function not implemented
shared memfd open() failed: Function not implemented
- build without tags:
./default
fatal error: unexpected signal during runtime execution

So this seems to be a problem in the underlying GLFW and SDL2 libraries.
SDL2 just does not currently seem to support it. I am not sure why or what the problem really is. Maybe you could spend some time investigating this and post some reference information about it here?
The GLFW SwapBuffers call is the one where the drawn frame gets rendered to the monitor, so to speak. The segfault looks like the C code is having a problem. Go's error messages are often not very helpful when CGo code crashes. I am not sure why this happens either. Maybe you could try to debug this a little more and find the root of the problem.
Currently I am not well prepared to reproduce this issue. I have neither an Android phone to try this out on, nor do I have an Android emulator and honestly this seems like a lot of work to me. That is why I am asking you whether you can inspect these issues further, as you seem to have your device up and running already.
Generally some repos will tell you that bugs in their dependencies are not their problem but I disagree with that sentiment. If there is a thing that I have to implement in SDL2 or a bug to fix in GLFW I will try my best to do that. But as I said, in this case I do not feel prepared to even reproduce this issue.
I can try it in summer..........
Sure, I will close this issue then. Feel free to re-open it or open a new one when you are ready.
