C "wcslen" and your C++ "wcslen" have completely different symbol
names.  C++ one is mangled, so C one in libc doesn't match it.

It may be easier if you use "nm" on your C++ compiled object files
to see what are the actual symbol names for the functions included
in it.

The reason for 'extern "C"' and what it does to symbols in C++ code
is well explained here:
