I just made a program but I want to test it in Release Mode but every time I try to build it it gives me this:

It builds and runs fine in debug but not release.
Any help is GREATLY appreciated.

Are you providing the correct linker flags for the release build? That's the first thing that comes to mind for me.

Are you 100% sure that you are linking the same libs in the same order?

huh? Linker Flags? Please explain.

Edit: Never mind I fixed it. I found someone with a similar problem online.
All you need to do is:

Code: Select all

#pragma comment( lib, "SDL.lib" )
#pragma comment( lib, "SDLmain.lib" )
#pragma comment( lib, "SDL_image.lib" )
#pragma comment( lib, "SDL_ttf.lib" )
#pragma comment( lib, "SDL_mixer.lib" )

Another Edit: I never learned about what #pragma did so yeah.

Linker errors suck. And just go back and make sure you've linked all the SDL stuff the way you're supposed to
