Description Luke-Jr 2021-06-17 21:49:14 UTC
The Chromium ebuild installs libEGL.so and libGLESv2.so to /usr/lib64/chromium-browser/swiftshader, but at runtime, libEGL.so fails with "gl_initializer_linux_x11.cc(124)] : eglGetProcAddress not found." (seen on chrome://gpu/ )

Replacing these bundled libraries with symlinks to the system versions seems to get things working.

Most likely this change broke ShiftShader with GCC:

https://swiftshader-review.googlesource.com/c/SwiftShader/+/48148

That change made all previously exported functions hidden. I'm testing if it helps to re-add __attribute__((visibility(\"protected\"))).

But it *does* work, with the system libEGL/libGLESv2 (which AFAIK are built with GCC)...?

The ShiftShader libraries are an alternative CPU based implementation of OpenGL ES/EGL and have the same interface as mesa libraries. The goal was to provide something that is GPU independent.
