[Numpy-discussion] Building Numpy with OpenBLAS

[Michael Sarahan]

I'm not sure about the mingw tool chain, but usually on windows at link
time you need a .lib file, called the import library.  The .dll is used at
runtime, not at link time.  This is different from *nix, where the .so
serves both purposes.  The link you posted mentions import files, so I hope
this is helpful information.

Best,
Michael
