I am used to programming in Xubuntu Linux with Anjuta... however, circumstances have forced me into Windows XP... as Anjuta isn't available for Windows, I decided to get Code Blocks; among other things maybe I'll take it back with me. Anyways, I'm trying to build my project which has dependencies on SDL, SDL_Image, SDL_Gfx, and Box2d. Now I've tried take care of this myself, but despite my efforts I have ended up with the following error message:
undefined reference to 'SDL_strlcpy'
undefined reference to 'SDL_GetError'
undefined reference to 'SDL_SetModuleHandle'
undefined reference to 'SDL_strlcpy'
undefined reference to 'SDL_strlcat'
undefined reference to 'SDL_strlcpy'
undefined reference to 'SDL_strlcat'
undefined reference to 'SDL_strlcpy'
I know that there are no problems with Box2d... I am very sure of that. So if anyone could point me to a guide or tell me what I did wrong or something?

Assuming that you have setup the link libraries correctly, keep in mind that libraries link order matters.

I have setup the link libraries correctly as far as I can tell, and appon reading your message corrected the order, as far as I can tell, but I still cant get it to work, getting the new message...

Is SDL compiled as a static or as a dynamic lib?
-
I dunno... whatever the SDL site supplies it as... probably dynamic...
-
Hm, then it looks like you missed to link a lib. You could try to search for the missing symbols inside the library files of SDL. Unfortunately the explorer serach inside function doesn't work properly for binary files anymore on XP, in win2000 it worked correctly (and the threaded search of CB crashes it if you try to search in .a). So you'll need some other utility to perform the search (grep in msys works for example).
-
most likely a library is missing, try to find the missing functions in the reference manual, find out in which library they are put and check if you have added this library in your linker options (make sure you did it both for release and debug targets)
