Hi, I am learning SDL, I got the following error when I building the project
codeblocks-mingw/current/MinGW/bin/…/lib/gcc/x86_64-w64-mingw32/8.1.0/…/…/…/…/x86_64-w64-mingw32/lib/…/lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o):crt0_c.c:(.text.startup+0x2e): undefined reference to `WinMain’
collect2.exe: error: ld returned 1 exit status
No problem with 2.0.14, any idea?
Edit: I don’t know but after comment this line in SDL_main.h the program can be build successfully
//#define main SDL_main
This is the source code that I am learning:
#include <stdbool.h>
#include <SDL.h>
bool is_running = false;
SDL_Window* window = NULL;
SDL_Renderer* renderer = NULL;
bool initialize_window(void) {
if (SDL_Init(SDL_INIT_EVERYTHING) != 0 ) {
fprintf(stderr, "Error initializing SDL.\n");
return false;
}
// Create a SDL Window
window = SDL_CreateWindow(
NULL,
SDL_WINDOWPOS_CENTERED,
SDL_WINDOWPOS_CENTERED,
800,
600,
SDL_WINDOW_BORDERLESS
);
if (!window) {
fprintf(stderr, "Error creating SDL window.\n");
return false;
}
// Create a SDL renderer
renderer = SDL_CreateRenderer(window, -1, 0);
if (!renderer) {
fprintf(stderr, "Error creating SDL renderer.\n");
return false;
}
return true;
}
void setup(void) {
}
void process_input(void) {
SDL_Event event;
SDL_PollEvent(&event);
switch (event.type) {
case SDL_QUIT:
is_running = false;
break;
case SDL_KEYDOWN:
if (event.key.keysym.sym == SDLK_ESCAPE)
is_running = false;
break;
}
}
void update(void) {
}
void render(void) {
SDL_SetRenderDrawColor(renderer, 255, 0, 0, 255);
SDL_RenderClear(renderer);
SDL_RenderPresent(renderer);
}
int main(int argc, char **argv) {
is_running = initialize_window();
setup();
while (is_running) {
process_input();
update();
render();
}
return 0;
}
