windows conda cfunits

[daniel-mohr]

If I try to use cfunits from miniconda on windows I get:

python -c "import cfunits"

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Miniconda\lib\site-packages\cfunits\__init__.py", line 47, in <module>
    from .units import Units  # noqa: F401
  File "C:\Miniconda\lib\site-packages\cfunits\units.py", line 226, in <module>
    assert 0 == _ut_unmap_symbol_to_unit(_ut_system, _c_char_p(b"Sv"), _UT_ASCII)
AssertionError

Sorry, I have no idea and also I'm not sure that this is an issue of cfunits. ?

Hi Daniel, which version of cfunits are you using?

(I should add that I have never tested cfunits on windows. I'll have a little look at the code ...)

Sorry, I'm also not familiar with windows. I just tried on github actions to run my software on windows and got more or less above error.

conda used cfunits-3.3.3.

I now created an explicit test for cfunit. Maybe this minimal test on windows could be integrated in the github actions here?

I got it running by explicit set an environment variable, e. g.:

jobs:
  windows-2016_test_cfunits:
    runs-on: windows-2016
    steps:
    - name: conda init powershell
      run: |
        &($env:CONDA + "\Scripts\conda") init powershell
    - name: install dependencies via conda
      run: conda install -c conda-forge cfunits
    - name: python -c "import cfunits"
      run: |
        $env:UDUNITS2_XML_PATH = $env:CONDA + "\Library\share\udunits\udunits2.xml"
        python -c "import cfunits"

  windows-2019_test_cfunits:
    runs-on: windows-2019
    steps:
    - name: conda init powershell
      run: |
        &($env:CONDA + "\Scripts\conda") init powershell
    - name: install dependencies via conda
      run: conda install -c conda-forge cfunits
    - name: python -c "import cfunits"
      run: |
        $env:UDUNITS2_XML_PATH = $env:CONDA + "\Library\share\udunits\udunits2.xml"
        python -c "import cfunits"

But I do not think this is a nice way. But unfortunately I do not know better to use conda and/or windows. :-(

Hi Daniel,

OK, good - the use of UDUNITS2_XML_PATH is documented at https://ncas-cms.github.io/cfunits/installation.html - I should have spotted the error message you were getting as being highlighted in that doc page! Thanks for working through it.

All the best, David

Hi David,

is it interesting for you to include such a github action for windows? Should I try?

Regards, Daniel

[davidhassell]

Hi Daniel - if you would like to submit a PR for that, that would be most welcome. David

Hi David,

I tried now to create a CI workflow in #29.

Regards, Daniel
