in fact I was in Single-threaded mode while compiling test001.cxx.
Although, I still have the same errors after switching to Multi-threaded Debug mode, but i may have also built the library in single-threaded mode by mistake.

Hi Eric,
You need to switch the runtime library settings to "Debug Multithreaded"
instead of "Debug Multithreaded DLL". In the project settings, this
setting can be found under C/C++ -> Code Generation -> Runtime Library.
Cheers,
