Hi,
If you have installed CW5.2 you can add missing derivatives by attachment ( cw 5 2 missing pieces v3.zip (41,780 KB) ) in
https://community.nxp.com/t5/Classic-Legacy-CodeWarrior/How-to-Add-missing-derivatives-to-CodeWarrio...
The files are text files and the package also contains required g64.h in the folder cw 5 2 missing pieces v3(2).zip\Lib\hc12c\include\
Best regards,
Ladislav
