`error LNK2019: unresolved external symbol zgtcon_` under Windows about ndarray-linalg HOT 4 OPEN

Did you try the intel-mkl-static backend? On Windows, it works for me with:

ndarray = { version = "0.15", features = ["blas"] }
ndarray-linalg = { version = "0.15", features = ["intel-mkl-static"] }

from ndarray-linalg.

It looks like these symbols are missing from the openblas.dll which vcpkg installed.

For example the linker complains about missing dgetrf_, dgetri_ and dgetrs_ and when I look at the symbols in the DLL the closest match I can find are dger_ and dger_k.

I downloaded the release package from the OpenBLAS repository. The DLL compiled by vcpkg is suspiciously small (only 1.7 MB) while the DLL from the OpenBLAS repo is 50MB.

When I replaced the files produced by vcpkg with the ones from OpenBLAS the linker errors went away and my program is working.

@relf It didn't work when I tried it the first time..
