AW: Undefined Reference

Title: AW: Undefined Reference

Dear Eddie,

for me it looks like, that the cross gcc does not use the startup and standard libraries, or they are missing.
You may add them manualy or use the "correct" environment (whatever it means ;-)

Startups are named like crt*.o
Libraries like lib*.a

With best regards and a nice day,

Try compiling in verbose, gcc prints out information showing where it found subprograms it invoked..
ex
<xxxx>-gcc -v -S hello.c
