g++ compiler complains about conversions between related types (from int to enum, from void* to class*...)

g++ compiler complains about conversions between related types (from int to enum, from void* to class*, from const char* to unsigned char*, etc.). Compiler handles such convertions as errors and won't compile furthermore. It occurs only when I compile using Dev-C++ IDE, but when I compile the same code (using the compiler which Dev-C++ uses) such erro开发者_C百科rs (even warnings) do not appears. How to mute errors of such types?

I suspect that in one case you are compiling your code as C and the other as C++. In C++, there is no implicit conversion from void * to any other type of pointer, and a C++ compiler which did not diagnose this as an error would be broken. You need to supply more details of how you are compiling your code.

Also, DevC++ is a pretty awful piece of code. It's buggy and no longer being actively developed, as well as being butt-ugly. You should seriously consider switching to a more modern and capable IDE, such as Code::Blocks.

All of your implicit conversions are disallowed in standards conforming C++. G++ is simply enforcing these rules.
