I am currently trying make an game with GTK4 and OpenGL. But I get a “Segmentation fault”. It appers when I try to draw a cube. Could anyone help me fix it. I use C99 and Linux Ubuntu 24.04
That’s my stats:
Vendor : AMD
Renderer: AMD Radeon 660M (radeonsi, rembrandt, LLVM 19.1.1, DRM 3.59, 6.11.0-25-generic)
OpenGL : OpenGL ES 3.2 Mesa 24.2.8-1ubuntu1~24.04.1
GLSL : OpenGL ES GLSL ES 3.20
You’ll need to run your code under GDB, and install all debug packages from your distribution.
There’s not other way for doing that? Like I need it for release.
That’s the only way to know what “Segmentation fault” means. Nobody else can do that, because we don’t have access to your computer.
lemme test.
that’s the output.
