What's an "[Linker error] undefined reference to..."

[mouse]

Hi there,

I've just downloaded a bunch of files so I can do SDL stuff. Using some sample code from a gametutorials.com tutorial I recieve a large number of errors like the following:[Linker error] undefined reference to `SDL_WM_ToggleFullScreen'So something's obviously wrong, is it the sample code or are my headerfiles b0rked?

I don't think its the header files, I think its the sample code, it would appear that its making reference to files that can't be found so the link would be like a shortcut the only problem is the other end of the shortcut doesn't exist.

it can not find your developement files for sdl (the .h files and stuff). if you are using linux, make sure you have sdl and sdl-devel installed if your are using rpms or compile it from source.

did you link with the SDL library file? its probably a .a or .lib file.
