Yes, I did see the part about the -include. I didn’t specify it because Xcode does the right thing by default. There was also no preprocessor error in the stats.
Attached a log but I don’t see anything wrong with it. Also updated to 3.2.7 but didn’t change something so far. I’ll keep looking too. Thanks! Guillaume
