[Moved] unresolved external symbol _SDL_GetError

[mike4]

main.obj: -1: error LNK2019: unresolved external symbol "_SDL_GetError" in function "" int __cdecl LoadGLTex (char *, int) "(LoadGLTex @ @ @ Z YAHPADH?)".

I've added the libs and headers so why i get this error?
Many thanks
Michael

What does this have to do with Qt? You forgot to add some SDL library or so it seems.

I want to use Qtcreator but have no clue why i get this error. It even works in VS and Eclipse.-
Tried with a *.pro alike below, any ideas what's going wrong?
Thanks Michael
