codeblocks and romdisks

Hi!

I'm working on a Dreamcast project under Codeblocks (thanks to Dc dev R4).

What I would like to do is to add a romdisk (it does help sometimes) so I create it easily with the tools and in my code I write SDL_INIT_ROMDISK(romdisk);

But i get an error! "undefined reference to romdisk".
Everytime I add a library I must change some paths in the "compiler and debugger option". I guess it has something to do with that...

thanks!
