undefined reference to `SDL_setRenderDrawColor'

Question

I am getting

C:\Users\rasmu\AppData\Local\Temp\ccwOn3mM.o:main.c:(.text+0x11f): undefined reference to `SDL_setRenderDrawColor'

C:\Users\rasmu\AppData\Local\Temp\ccwOn3mM.o:main.c:(.text+0x155): undefined reference to `SDL_setRenderDrawColor'

when i try to compile my basic SDL2 c program. My code is

#define ASSERT(_e, ...) if (!(_e)) { fprintf(stderr, __VA_ARGS__); exit(1); }
#include <SDL.h>
#include <stdio.h>
#include <stdbool.h>
#include <stdint.h>


typedef float f32;
typedef double f64;
typedef uint8_t u8;
typedef uint16_t u16;
typedef uint32_t u32;


const int SCREEN_WIDTH = 1280;
const int SCREEN_HEIGHT = 720;
const int FPS = 30;

typedef struct {
    SDL_Window* window;
    SDL_Texture* texture;
    SDL_Renderer* renderer;
    u32* pixels;
    bool quit;
} state;

u32* init_pixels();
void put_pixel(state state);

int main( int argc, char* args[]){
    state state;
    ASSERT(
        !SDL_Init(SDL_INIT_VIDEO),
        "SDL failed to init: %s\n",
        SDL_GetError()
    );
    state.window = 
        SDL_CreateWindow(
            "Game",
            SDL_WINDOWPOS_CENTERED_DISPLAY(1),
            SDL_WINDOWPOS_CENTERED_DISPLAY(1),
            1280,
            720,
            SDL_WINDOW_ALLOW_HIGHDPI
        );
        
    ASSERT(state.window, "failed to create SDL window: %s\n", SDL_GetError());
    state.pixels = malloc(SCREEN_WIDTH * SCREEN_HEIGHT * 4);

    state.renderer =
        SDL_CreateRenderer(
            state.window,
            -1, 
            NULL
        );

    SDL_setRenderDrawColor(state.renderer,0,0,0,255);
    SDL_RenderClear(state.renderer);
    SDL_setRenderDrawColor(state.renderer,255,255,255,255);
    SDL_RenderDrawPoint(state.renderer,SCREEN_WIDTH/2,SCREEN_HEIGHT/2);
    SDL_RenderPresent(state.renderer);

    while(!state.quit){
        SDL_Event ev;
        while(SDL_PollEvent(&ev)){
            switch(ev.type){
                case SDL_QUIT:
                    state.quit = true;
                    break;
            }
        }
    }


        
    
    SDL_DestroyWindow(state.window);
    free(state.pixels);
    SDL_QUIT;
    return 0;
}

And my make file looks like this

OBJS = main.c

CC = gcc

INCLUDE_PATHS = -IC:\mingw_dev_lib\include\SDL2

LIBRARY_PATHS = -LC:\mingw_dev_lib\lib

COMPILER_FLAGS = -w -Wl,-subsystem,windows

LINKER_FLAGS = -lmingw32 -lSDL2main -lSDL2 

OBJ_NAME = game

all : $(OBJS)
$(CC) $(OBJS) $(INCLUDE_PATHS) $(LIBRARY_PATHS) $(COMPILER_FLAGS) -o $(OBJ_NAME) $(LINKER_FLAGS)

I do believe it has something to do with the linking of the SDL2 library but it seems weird since the SDL.h works fine but only when I have tried to use the SDL_setRenderDrawColor() function. I am quite new to SDL and linking libraries.

Looks like a typo since the compiler isn't complaining about the other SDL function calls. You probably need to change SDL_setRenderDrawColor to SDL_SetRenderDrawColor
