You need to put extern "C" around the includes that declare those rt
functions. The undefined symbols you got were the C++ "mangled" names
that include argument types in the string. Plain old C doesn't do
that.
Ideally, any C include file, such as the rt .h files, should have
something like this in it:
#ifdef __cplusplus
extern "C" {
#endif
<body of file>
#ifdef __cplusplus
}
#endif
That way it will compile correctly with either compiler.
