don't know whats up with the strike throughs...

[ericstoneking]

I blame overzealous auto-markdown-formatting.

Thanks for the warnings. My system is apparently overly permissive. I'll look into them.

not sure of whats being passed but it works on AMD64 VMware Fusion...but not ARM64 (Apple M1) VM.

is libgallium associated with freeglut3-dev?

[ericstoneking]

Googled "libgallium", and it appears to be part of Mesa. Maybe updating Mesa would help.

Have you tried using GLFW instead of GLUT? Look in the Makefile for "GLUT_OR_GLFW" and set it to "USE_GLFW".

[ex0atmospheric]

ok...ran the code through Claude Code and there are 2 modified files. its working now.

1. Source/42init.c — the orphaned %[\n] specifier in the orbit spline format strings (missing &newline argument caused fscanf to
   write through a garbage pointer)
2. Kit/Source/glkit.c — glBitmap / glutBitmapCharacter crashing inside Mesa 25.2.8 + LLVM 20.1 on aarch64; replaced with a
   GL_POINTS-based renderer that walks the Font8x11 bitmap data directly, bypassing glBitmap entirely. DrawString8x11 now delegates
   to the same renderer.

42init.c

glkit.c

Just fyi, I tried those patches on my machine, a system76 laptop running Pop!_OS 22.04 LTS and it fixed the problem -- builds successfully and runs with GUI. Thanks, ex0atmospheric!
