Segmentation fault on start

Gallaecio commented 5 years ago

SuperTux version: 0.6.0 System information: Linux 4.19.26-1-CHAKRA #1 SMP PREEMPT x86_64 GNU/Linux

The game crashes upon start with a segfault:

$ supertux2 
Segmentation fault (core dumped)

GDB output:

(gdb) bt

It may be related to #779.

I can reproduce the issue with master (ce839a6b084d0d50c89b08705434ff65dc858f79) with a package built using the supertux-git source package from the Arch User Repository.

What is your graphics card?

Run supertux --verbose and post the output.

Also try:

supertux2 --renderer opengl

supertux2 --renderer opengl20

supertux2 --renderer sdl

Gallaecio commented 5 years ago

Both supertux2 --renderer opengl20 and supertux2 --renderer sdl work. supertux2 --renderer opengl crashes.

What graphics card are you using? Post the full output of glewinfo.

Might be that GLEW 1.10 is to old or has a bug, as Vertex Array Objects should have been supported since 1.5.1.

Another suspicious thing is "GLEW_ARB_texture_non_power_of_two: 0", that should be 1 for anything but completely ancient video cards, so probably something going wrong with GLEW initialization.

glewinfo.txt

Grumbel commented 5 years ago

Little out of ideas here. Try recompiling with a newer version of glew. Your glewinfo output looks proper and contains all the necessary stuff, but within SuperTux they go missing, e.g.:

GL_ARB_texture_non_power_of_two:                               OK

and in SuperTux:

GLEW_ARB_texture_non_power_of_two: 0

Same with glGenVertexArrays I assume.

I upgraded to glew 2.1.0 and rebuilt, and it worked. Thanks!
