无法使用SDL_gfxPrimitive

Question

I´m trying to use the filledCircleRGBA function from the _gfxPrimitive lib from SDL2, but it says 'fatal error:SDL2_gfxPrimitives.h: No such file or directory

I have both includes and I use -lSDL2 and -lSDL2_gfx on the command line

#include <SDL.h>    
#include <SDL2_gfxPrimitives.h>

int main() {
    SDL_Window* g_pWindow = NULL;
    filledCircleRGBA(g_pWindow, 2, 4, 4, 255, 255, 255, 255);

return 0;
}

Why can´t I use _gfxPrimitives functionalities? I have the -dev SDL2 installed, so it should have all the libs

Answer 1

Installed with SDL2 is sdl2-config , a program which you run with parameter --cflags or --libs . Pass the output of using either parameter to your compiler and linker, respectively. --cflags is particularly what you need, as it instructs the compiler to add the SDL2 include directory to your compiler's search path.
