libMagnumEglContext is still forced to static. flextGLInit is not an exported symbol.

Amazing, thanks for updating and testing this side as well 👍

Yes, those are deliberately static everywhere always since they're extremely tiny and are meant to be only used from the top-level application executable/library to initialize GL, and from nowhere else after that. Given that usage pattern, so far there weren't any problems with that, but of course let me know if your use case would be different.

In my case, it works well. But EGL is used by only one of my shared libraries.

Merged as a9898a0, sorry for the delay. The MAGNUM_BUILD_PLUGINS_STATIC is however still forced on Android, because the PluginManager itself doesn't have any support for loading dynamic libraries there. It'd need to get implemented in it first. I think it's not as much of a problem for the plugins, since they're relatively small and don't contain any shared mutable global state that could cause problems.

I also mirrored this change in other repos as mosra/magnum-plugins@127a9ec, mosra/magnum-extras@f567dba and mosra/magnum-integration@35c05fd.

Thank you!
