Undefined reference to xxx with arm-elf-gcc

[Christian Narvaez]

I am having some problems compiling for an arm with arm-elf-gcc. 
The problem apears when linking of the type undefined reference to ...
Here is a part of the error messeges. I already tried -lgcc and -lc but
that dous not work. Christian
