SDL2 - Undefined references - Ubuntu
I just started using SDL2 (on Ubuntu 13.04 x64) and everything was going
fine, until I tried to use SDL_image.
I added this piece of code, for loading images:
SDL_Texture* LoadImage(std::string file)
{
SDL_Texture* tex = NULL;
tex = IMG_LoadTexture(ren, file.c_str());
if (tex == NULL)
throw std::runtime_error("Failed to load image: " + file +
IMG_GetError());
return tex;
}
I link with -lSDL2 and -lSDL2_image, and I get this undefined references:
g++ -o "SDL" ./src/main.o -lSDL2 -lSDL2_image

What am I doing wrong??
