Build errors on arch linux

[derkrasseleo]

I don't know if I have installed all dependencies correctly, do you know what could be the problem here?

[mika314]

I have to remove ffmpeg from my dependencies, I only use it to load audio and it is a headache.

[derkrasseleo]

So I don't have a wrong version or something? Because I read here that in a newer version, they deprecated AVStream

[mika314]

I'll just remove the dependency of ffmpeg completely. I will do it some day.

I confirm the issue in Manjaro as well: In file included from /usr/include/SDL2/SDL_opengl.h:38: /usr/include/SDL2/SDL_config.h:542:58: warning: '_HAVE_STDINT_H' is not defined, evaluates to 0 [-Wundef]
