Testing compilation procedure for LIBSTELL +gcc9 under msys64 on windows

[gmweir]

Goal: Support compilation of a shared libstell.dll that is usable with python on windows machines.

• Numpy currently supports shared libraries under ctypes, but not static libraries
• Most users at IPP-Greifswald have windows VMware machines without administrative privileges.
• Instead of maintaining many separate unsupported toolchains (wout parsers, etc.), we should encourage use of the tools provided by the core developers within LIBSTELL.

Status: with GCC9.3 under msys64+mingw64 on windows 10

• serial / parallel static libraries successfully compile (libstell.lib)
• serial shared LIBSTELL library successfully compiles (libstell.dll)
• testing on mac-osx Catalina

Requests: 1) Testing required modifications to makefiles under traditional build-systems (HPC, mac osx, etc.) 2) Testing and development of PYSTELL

Note: The mscompile branch is based off of the Lazerson branch

Successful compilation of most modules with and without MPI (shared and static libstell) on Mac OSX Catalina

The following modules need the HOTFIX for mpi variables with for NO IMPLICIT KIND:

• beams3d
• diagno
• fieldlines
• vmec2000 Although most of these modules only make sense to run with a parallel build. Fieldlines and VMEC2000 should still function serially.

@gmweir Status?

[gmweir]

Success! The xvmec.exe and libstell.dll have been tested a bit, but the accuracy does not yet pass the benchmarks for the ATF and DSHAPE tests.

The compilation works though!
