glfw Opengl4 demo Segmentation fault
- I'm trying to run glfw3 opengl4 demo example.
make
rm -f bin/demo
cc main.c -std=c89 -Wall -Wextra -pedantic -O2 -o bin/demo -L/usr/local/lib -lglfw3 -lGL -lm -lGLU -lGLEW
Everything compiles fine.
but then:
./bin/demo
Segmentation fault (core dumped)
I see a black window and then it closes. 2) OpenGL 3, OpenGL 2 and Sdl examples works fine.
- I'm trying to use gdb to find out where program fails:
cc main.c -ggdb -std=c89 -Wall -Wextra -pedantic -O2 -o bin/demo -L/usr/local/lib -lglfw3 -lGL -lm -lGLU -lGLEW
gdb bin/demo
run

I think this is because of GL_ARB_bindless_texture functionality. Without this option example works fine. Does this bug occurs because of my amd drivers?

I can't find list of supported opengl functions for my drivers..
Related: https://github.com/Immediate-Mode-UI/Nuklear/issues/190 - sounds like the same or similar case.
I am no expert on OpenGL so I would need to spend some more time educating myself about the details. Currently I am out of time, but perhaps someone more knowledgeable will chime in :wink:.
Probably a driver issue, doing the same on Linux (6.4.6) with an Nvidia card (RTX 2080), the program runs without any issue.
With Nvidia, there is nvidia-settings which gives detailed information about the device :
Isn't there a similar tool with AMD?
@riri glxinfo shows the GLX settings for AMD. GLX_ARB... and other functions are there. Although, I have the same problem as mentioned above.
I'm getting these errors:
