What camera are you building?
Digic I-VI
Edit: Appended my
failing files, which could be suspicious?
Edit2:
Given that the autobuild works, I'd guess there's something you should have touched but didn't. This function was added in the ximr branch 
Missed some lines in core/shooting.c:
#ifdef CAM_HAS_PLAYBACK_IMAGE_NO
What´s that?
Edit3: Found in G12, G1x, G5x, G7x2
