Ren’Py apps crash after splash screen

[HappyRespawnanchor]

Describe the issue

In live container, any app made with the Ren’Py engine crashes immediately after the splash screen is displayed.

If sideloaded directly in SideStore, it runs normally.

Instructions to reproduce

RPReplay_Final1734839262.mov

What version of LiveContainer are you using?

Version 3.1.0-release (main/c586e79)

Well, after some investigation, I found that this is an issue with dlsym. DDLC linked against both OpenGLES and MetalENGLE , which both contain OpenGL api. If directly sideloaded, dlsym correctly returns OpenGL functions in MetalENGLE, while in LiveContainer, OpenGLES functions are returned, and since no OpenGL context is setup, glGetString returned 0 and DDLC crashed.

If I force dlsym to return functions in MetalENGLE, DDLC can launch without issue. I'm looking for a way to make dlsym behave "correctly" like when being sideloaded.

Before this issue is resolved, could you add a debug option to select which library (MetalENGLE or OpenGLES) OpenGL functions are returned from for testing? :)

感谢，确实解决了，话说hugeBlack/LiveContainer的commit未来会被推到khanhduytran0/LiveContainer吗
