Seriously? If I have MSVC 2010 installed, pip install numpy will
correctly build numpy from source? It's a *long* time since I tried
this, but I really thought building numpy was harder than that.
A quick test later:
No BLAS/ATLAS/LAPACK causes a string of warnings, And ignoring the
rest of the error stack (which I'm frankly not interested in investing
the time to diagnose and fix) I get "RuntimeError: Broken toolchain:
cannot link a simple C program". Which is utter rubbish - I routinely
build extensions with this installation.
So no, numpy does not build out of the box. Ah well.
