Hello
It looks like CodeWarrior Coldfire compiler has more strict type checking than the compiler you have been using before.
In order ti be able to build your application you can either fix the source code to avoid the conversion the compiler does not like or try to add option to the compiler to process your source file.
How to fine tune the compiler depends on the source code.
I would start with checking "Enable GCC extensions" in the target "C/C++ Language panel" .
If this does not help, I would recommend to submit a service request through our on-line support web page and attach the project.
Our support engineers will then be able to assist you.
