[SciPy-User] Building Scipy -Build from source on windows

[Olivier B.]

I had the same error when building with Visual C++ / gfortran of mingw / mkl
The only ugly workaround i have for now, was to 'tweak'
numpy/distutils/fcompiler/__init__.py, in link(), so i can pass by an
environment variable mkl_rt.lib at the correct position on the
grfortran command line (it must be after the compiled objects
contained in ld_args)
You can find at https://github.com/scipy/scipy/issues/10736 the issues
i encountered to manage sucessfull build for this config
