Anything else you feel useful to add?

I've confirmed this on Firebase Test Lab with our Ebitengine application.

My guess is that __LP64__ is not defined on this device, but I am not 100% sure.

Even with C's RTLD definitions, another crash happened.

I'll try to replace all the dlopen part with C version later.

[hajimehoshi]

In v2.7, PureGo is not used for this part https://github.com/hajimehoshi/ebiten/blob/2.7/internal/graphicsdriver/opengl/gl/procaddr_linbsd.go

[TotallyGamerJet]

A quick solution is to just revert the change in procaddr_linbsd. I wonder if this is a sign that arguments are not being passed correctly in arm64. Perhaps trying purego.SyscallN instead of RegisterFunc. It’s unclear from the last error if this is a call to an OpenGL function or to Dlopen

[hajimehoshi]

I've confirmed that the fix worked on Test Lab.

[hajimehoshi]

I've almost reverted the Android part, but not non-Android Linux part. So, there might still be an issue on Linux, but I don't know what machines an issue. On Linux, the constants RTLD_* always seem the same, so this might be different from Android.

This is due to your device’s OS. Despite your processor being a 64-bit model, which is now a requirement for Infinite Flight to be installed, your phone has a 32-bit version of Android. Why Samsung has done it for this device is beyond me, however, it means that you will not be able to install IF on your Samsung Galaxy A02s, as your phone is recognized as a 32-bit one.
