Hi edenli,
What's the error in S32DS v1.2 ? Perhaps you should report it to S32DS S32 Design Studio Community.
Regarding the old IDE (which i honestly don't know how to use it) i seems like you need to add a define like this
SWLIBS_DEFAULT_IMPLEMENTATION=SWLIBS_DEFAULT_IMPLEMENTATION_FLT
This is how you do it in S32DS but i do not find a way to add in CW IDE.

Best regards,
Daniel
