Output from gdb: Thread 1 "slic3r_main" received signal SIGSEGV, Segmentation fault. realize_glenv (ispoint=ispoint@entry=0, first=first@entry=0, count=count@entry=4, type=type@entry=0, indices=indices@entry=0x0, scratch=0xbeffa5ec) at /home//code/gl4es/src/gl/fpe.c:1114 1114 glprogram->texunits[tu_idx].req_tu = GetUniformi(glprogram, glprogram->texunits[tu_idx].id);
The error is this:
LIBGL: No EGL configs found.
LIBGL: ERROR: EGL Error detected: EGL_BAD_CONFIG
It found no EGL config, so no GLES context is created. Eveyrthing else is not relevent, the context is not there. The question is: why can't it create a context? Is there some strange RGBA combinaison asked for the OpenGL context?
I'm trying to compile PrusaSlicer (a 3D printing slicer) for the Pyra. It requires opengl v2.0 but does run slowly with mesa.
gl4es gives "Error: N" shader errors. What does "N" mean?
The shaders are on github:prusa3d/PrusaSlicer/shaders
