[QtonPi] Fwd: Raspian 20012-6-18 vs 2012-9-18 softfp vs hardfp? Compile issues

[Harri Pasanen]

Are you sure you've cleaned everything?

The errors would seem to indicate that object files compiled with 
incompatible flags are being linked together.

Safest is to have all the -m....  flags be the same across the system.

Just my 2 cents,

Harri
