source/main.cpp:120: undefined reference to `__gxx_personality_sj0'
thats the error i reference my sprite class in main, but it says the error is on the last line of the main.cpp file...

Probably a missing symbol, such as a semicolin or curley brace ({ and/or })? You might also check the header files you are including, too.

Missing semicolons or braces cause compile-time parse errors, not link-time "undefined reference" errors. It's likely that one of the C++-specific libraries isn't getting linked in correctly. Do programs written in C (not C++) work?

programs in C work...
programs written in C++ work too, until i use classes or try and use new or delete. So i had an idea that it was something to do with libs, but i dont know anything about the gcclibs.

Not my area of expertise, but simplest pitfall to make: are you remembering to use g++ instead of gcc for C++ programs?

i fixed it, it was the order the libs where being linked in, works like a charm now.
thanks guys
I get this warning along with this error....

Don't use ld directly when linking.
For C programs use gcc to link, for C++ use g++
The example projects in devkitPro cvs do this automatically and are a good starting point for any project.
