Can I compile NEURON on Windows with Cmake and Visual Studio 2019?

[Helveg]

I used CMake to generate the build files for Visual Studio 2019 and I tried building the generated solution, it produces various errors. From #319 I guess that compilation on Windows is not straightforward and that VS is also not the preferred way, so maybe I shouldn't look into this further at this point?

[nrnhines]

I foggily foresee a complete Visual Studio build but at present the bulk of the compiling requires MinGW with msys2. Only some
of the cython generated files for some of the python versions need to be compiled with Visual Studio. I'm guessing that the possibility of a complete Visual Studio build hinges on how many linux specific functions are being used that don't have immediate VS counterparts. To not lose the benefit of your attempt, perhaps you can mention how to reproduce your VS build with cmake and what kind of errors occurred.

I installed the requirements (BISON, FLEX, readline5) from WinGnu32, gave all their CMAKE flags and installed Intel MPI. That made CMake happy, then I optimistically opened NEURON.sln and pressed "Build solution"

This is the list of errors, but they don't appear to be very informative:

[pramodk]

@Helveg : I would suggest you to wait for ~ a week as I am working on instructions for neuron build on windows (see #572, got distracted because of other work).

If you need latest NEURON for windows, I would suggest to grab installer from https://github.com/neuronsimulator/installers

[Helveg]

Sounds good @pramodk !

[alexsavulescu]

For reference, how to build on Windows (msys2 + mingw): https://nrn.readthedocs.io/en/latest/install/windows.html

@matz-e has had a stab at native building during the 2022 hackathon here: https://github.com/neuronsimulator/nrn/tree/fenster-bauen

And alternatively, one can use

• the linux wheels via WSL: https://nrn.readthedocs.io/en/latest/install/install_instructions.html#windows-subsystem-for-linux-wsl-python-wheel
• the Windows Installer: https://nrn.readthedocs.io/en/latest/install/install_instructions.html#windows
