I wanted to include xf86drmMode.h in my c code, but when I did it says there was an error in the header file as it couldn’t find drm.h. It’s because there is no drm.h on my system, there’s only libdrm/drm.h. What am I meant to do? Edit the header? I mean I guess I could but would that cause issues in my system?
I tried using sudo pacman -Syu linux-headers libdrm but nothing changed. Theres no straight up drm package either to install.
> ls /usr/include | grep "drm"
libdrm
xf86drm.h
xf86drmMode.h
> ls /usr/include/libdrm

>Solution :

Add /usr/include/libdrm to compiler include search path.
Typically a build system is used. Looking at the output of pacman -Ql libdrm I see pkgconfig. Use:
gcc $(pkgconf --cflags --libs libdrm)
to compile programs. If you check pkgconf --cflags --libs libdrm you’ll see it adds -I/usr/include/libdrm to compile include search paths.
Edit the header?
No.
would that cause issues in my system?
Yes.
