windows build ?

[jschueller]

is it possible in conda-forge ? seems defaults has windows builds of this

Looks like defaults uses https://github.com/jlblancoc/suitesparse-metis-for-windows/ I suppose we could do the same? It seems like a bit of a pain to maintain

Seems that upstream has performance issues with openblas:

About the BLAS and LAPACK libraries

NOTE: Use of the Intel MKL BLAS is strongly recommended. A recent OpenBLAS can result in severe performance degradation. The reason for this is being investigated, and this may be resolved in the near future. Ignore the comments about OpenBLAS in the various user guides; those are out of date.

I wanted to tackle the windows build because it's affecting me in downstream packages, and investigated as well what anaconda does. Seems they're still on 5.2.0.

So, apparently, cvxopt knows how to build suitesparse on windows. This is what AnacondaRecipes does, and it worked for me in conda-forge/cvxopt-feedstock#42 as well. Eventually, it would be nice to replace that hack by having the windows build done in this feedstock, of course.

Why close this issue? The oldest windows build is for 5.4.0, while master is on 5.10.1

oh I thought it was fixed
