I3 pro C Dual extruder: extruder running wrong direction

[julianoporto]

When sending a print job checked that the extrusion is retracting the filament. Carrying out the test in Repetier-host: extrude = retract and retract = extrude; I tried to compile the firmware (Marlin-PI3_Pro_C) and had an error:

exit status 1
unable to find a register to spill in class 'POINTER_REGS'

Please help!
