BUG: unable to build on Windows

[andyljones]

I'm trying to build this package on Windows and not having much luck. Using the mingw-w64 Fortran compiler (installed from Anaconda) and Visual Studio 2015, I get these errors:

glmnet5.o : error LNK2001: unresolved external symbol _gfortran_runtime_error_at
glmnet5.o : error LNK2001: unresolved external symbol _gfortran_internal_pack
glmnet5.o : error LNK2001: unresolved external symbol _gfortran_internal_unpack

A morning of Googling hasn't been much help. The closest I found was this StackOverflow question, but setting the compiler=mingw32 flag in setup.cfg leads to a different error, ValueError: Unknown MS Compiler version 1900.

Have you successfully built this package on Windows?

We have not yet built the package under Windows. Unfortunately, we do not have easy access to a Windows box. I'll do some digging through numpy and conda recipes to see if those are provide any hints.

I got this build/run on Windows 10 with a small change in the setup.py

@John3-16 , thank you for the report. What change? If it's a generally applicable fix, you could contribute it as a pull request.

A working Fortran compiler is also required to build the package

is it fixed pls?
