Compiling on Windows with gfortran

[pya]

Task

I am trying to compile the latest version on Windows.

Operating System

Windows version: Windows 10 Pro, latest updates applied

Steps installing the environment

1. Forked the development branch on GitHub
2. Cloned it to my local Windows system
3. Created a new conda environment with: mamba env create -f environment.yaml
4. Python version is 3.12.1
5. Activated the new environment
6. Installed gfortran and cmake with: mamba install -c conda-forge m2w64-toolchain_win-64 cmake

cmake and gfortran are found in the conda environment

where cmake
C:\Users\mike\mambaforge\envs\modflow6_dev\Library\bin\cmake.exe
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe

where gfortran
C:\Users\mike\mambaforge\envs\modflow6_dev\Library\mingw-w64\bin\gfortran.exe

with these versions:

cmake --version
cmake version 3.28.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

What did I miss?

[pya]

For now, I'll go with the nightly build. :)

Hi @pya, I see the same error on Windows with the m2w64-toolchain_win-64 conda package. You might try installing mingw either from Chocolatey or one of the distributions here, I think those should succeed.

[pya]

Hi @wpbonelli, thanks for the tip. Using the Chocolatey route worked. It compiled on the first try. But many tests fail.

Running the tests with the nightly build mf6.5.0.dev1_win64 from February 11, 2024, looks much better:

@pya The test failures you are seeing with the nightly build can be resolved by installing the mf2005 and mfnwt executables by running pytest get_exes.py from the autotest/ directory. They can also be installed manually from the distribution repo, in which case they will need to be moved to the location expected by the tests, <proj root>/bin/downloaded/. A third option is flopy's get-modflow utility command, for instance get-modflow : --subset mf2005,mfnwt bin/downloaded.

Note that by default, mf6 is configured to build in serial mode only — for more information on building the parallel version see this document. The recommended route to build parallel on Windows is WSL, it is possible with cygwin or msys2 but getting PETSc set up for native Windows is tricky.

A serial build on Windows 10 with a recent gfortran (>=10), and the latest flopy should pass all tests however. Please feel free to send the full test output to wbonelli [at] ucar [dot] edu, I am happy to take a look.

[pya]

@wpbonelli I used get-modflow to install mf2005 and mfnwt. They are available at the command line, but pytest does not find them. I copied them into bin\downloaded, where pytest finds them. Now all tests pass:

442 passed, 40 skipped, 336 warnings

The warnings are mainly deprecations from NumPy. Looks like a foreshadowing of the upcoming NumPy 2.0:

Usually, I work on macOS and Linux VMs in the cloud. These will work for parallel computations. I am happy with serial MF6 on Windows for now. I am also using WSL. Therefore, I would go for this option if I want to go parallel on Windows.

I will send you the pytest output for the test runs with gfortran.

@pya yes, we have some cleanup work to do for numpy 2 here and in flopy. As of last week flopy pins numpy < 2 so the mf6 conda environment should remain compatible regardless of the timeline, but we anticipate supporting v2 fairly promptly after it's released.

I received your email and will take a look.
