Compiling RLP does not do error checking - how to get working

i have altered the file in the RLP_User project, added some code and the compiler is fine with it, even though i have also add syntax errors.
how can i get the compiler to give out error messages and warnings?

This is not possible! The compiler will not ignore errors…it can’t

What kind of alteration and what file exactly and what code changes did you do?

sorry, false alarm.
was building the source from VS and had an environment variable set to the wrong dir.
It was building the unmodified code.
should have checked it before posting :-[
