Hi Tobias,

Thanks for the response.

I just put snippet of one error there are many errors in printf_hook.c but all are of same type as above (undefined reference).

I will try the same on ICS and will let you know if I come across with the same error.

Yes DROID_TARGET in vstr.build is changed accordingly.

Thanks for the clarification.
