Addition note:
I previously mentioned the libcharset\libtool don't have ar="" setted correctly.
It's ar="false" that's also because gcc is not exist.
the libtool in root also have wrong ar="ar" , rather than AR="/f/Software/Application/lib/libiconv-1.17/build-aux/ar-lib lib"
All those is caused because gcc is not exist.
That's weird!!!! but well now I got the msvc native compiled library!!!
