Installing GMP on VStudio 2017

[Person Withhats]

As it says up there... I really really need this fixed!

I've compiled and recompiled GMP using msys2, cygwin, etc. and none of them
work properly.

My edits to project options:
    Linker -> General: Additional Library Directories
    $(GMP_ROOT)\lib;%(AdditionalLibraryDirectories)

    Linker -> Input: Additional Dependencies (libgcc.a does nothing and
order for xx or not doesn't seem to matter)

C:\msys64\usr\lib\gcc\x86_64-pc-msys\6.4.0\libgcc.a;libgmpxx.a;libgmp.a;%(AdditionalDependencies)


    C++ -> General: Additional includes
    $(Boost_ROOT);$(GMP_ROOT)\include


I get a "unresolved external symbol __getreent (and fprintf) in function
gmp_default_allocate"


It just wont' bloody work, days wasted on this. Please advise.
