Missing mpl_key

Hi,

I'm trying to build the Motion Driver 6 beta for Atmel SAM4S, and I get stuck with the following linker error:
undefined reference to `mpl_key' in C:eclipseWSlibmplmpuDebug/../mpl/quaternion_supervisor.c

Seems that something is missing in the ARM library port libmpllib.a. Any hints please?

Cheers,
Kir

I ran into this same problem, one way around it is to include the following line of code in your main.c file:

unsigned char *mpl_key = (unsigned char*)"eMPL 5.1";


I did this with mine and it compiled.
