Here you are declaring a function which would be called Test in C (not C++).

Here you are telling it to look for _Test__Fv.  Here is the call statement
that the compiler generates.

call _Test__Fv

I think the linker for RSX doesn't give you errors about unresolved
externals, which is what you have.
Either rename your function in the nasm module, or specify to use C style
mangling in your extern (extern "C")
