Build JCC - Unresolved Symbol Error

Hi, I am trying to build JCC ver 2.20 on Windows 10, using Python 2.7, MSVS
C++ 2008 compiler. I am receiving following error message while installing :

Hi, I am trying to build JCC ver 2.20 on Windows 10, using Python 2.7, MSVS

Two things come to mind:
- try a more recent compiler, ideally the same version used to build your python installation
- make sure the version of the JNI headers you're
including correspond to the version of the java lib you're linking against.
