Re: CPP: Invalid convertions and sorry-unimplemented's error while translating it from C

There's not one problem here, there are a fair few. C and C++ are languages that are somewhat similar but do have their differences, and you're running into that. Either keep the code in C and link separate C++ code against it, or make sure all code complies to C++-standards.

I know about these problems, but I mean problems with structures
