This is an issue you'll get with any tool chain, so it may be a good 
question for comp.arch.embedded, or a "basic" group if there is one.

You get an "undefined symbols" error from a linker if there is someplace 
in your code where you have used a symbol (a function or a variable) 
without defining it.  In the case of a variable this means that you're 
doing something like:

extern foo;

...

foo = bar;

In the case of a function in C all you need to do is misspell a function:

int foo(int bar) {return -bar;}

ralph = fuu(34);

Usually your linker will tell you _which_ symbols are missing; look, and 
do a search through your source code for the offending symbol.
