My sdl2 library:

> ubuntu@ubuntu:~/Github/ioq3$ pkg-config --cflags --libs sdl2  
> -D\_REENTRANT -I/usr/include/SDL2 -Wl,-rpath,/usr/lib -Wl,–enable-new-dtags -lSDL2

It seems to me that the header should instead be included with: include “SDL2/SDL\_version.h”.  
Am I missing something here and doing something wrong?

Okay I found the issue. I was somehow missing files in /usr/include/SDL2. I did

> sudo apt-get install libsdl2-dev

and it now compiles.
