Hi,
Could you provide us with more details?
1) Which codewarrior version are you using?
2) Are you able yo build an empty project generated by project wizard for the MCU you are targetting?
3) The error message does not include any hint. Can you send us entire build console listing? e.g. are you able to bulild at least some .c files?
4) can you delete your output folder (e.g. DEBUG_FLASH) and rebuld the project?
This will helpl us to find a rootcause much faster
Thanks.
Stan
