Hi decoski,
Sorry for this lately reply, the NXP site was down last week and i check your ticket this week.
In the Release note of the AUTOSAR OS package, you can find a note of compiler requirements as below:

You should use the following version of all required tools/enviroments
I'm not so sure about the second issue but maybe it can related to the first one, so please help me to try re-install correct version of tools once again.
Thank you,
Nam.
