Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@conda-forge-admin, please rerender

Hi! This is the friendly automated conda-forge-webservice.

I tried to rerender for you, but it looks like there was nothing to do.

This message was generated by GitHub actions workflow run https://github.com/conda-forge/libnetcdf-feedstock/actions/runs/5611177105.

Build didn't hang, but I also don't see xarray or "test_netcdf" in the log at all.

[zklaus]

Yeah. I'll try to add a run_test.bat.

Incidentally, I did find this

For this reason, h5py is advertised for EITHER multithreaded use OR use alongside PyTables/NetCDF4, but not both at the same time.

It seems like windows is still not running tests @ocefpaf or anyone else, any insight into why that could be happening?

[djhoese]

FYI I'm working on a C-only example, but its been a while compiling C, not to mention never having done it in Windows, in a conda-forge environment, with the NetCDF library.

[zklaus]

Hmmpf. It just does not want to run the tests. Unless it does and we just don't see it.

I don't see any evidence it's even creating the test environment, which is really odd. It's almost like it think it's cross-compiling or something and it just skips testing.

[djhoese]

#include <netcdf.h>
#include <stdio.h>


int main() {
    int res, ncid;
    res = nc_create("test_netcdf_c.nc", NC_CLOBBER, &ncid);
    if (res) {
        printf("FAILURE!\n");
        return res;
    }
    printf("SUCCESS!\n");
    return 0;
}

But...I have no idea how to successfully compile it in Windows. No matter what I do it tells me that nc_create isn't defined. So that means I also have no idea if it causes things to hang.

@isuruf we are failing to get the Windows test o run here (or maybe we are not seeing the failures?). We could use your help. Our CIs setup became so complex lately that is quite hard to figure out what is going on under all these layers.

[isuruf]

Sorry about that. conda-forge/conda-forge-ci-setup-feedstock#256 should fix it.

[ocefpaf]

Sorry about that. conda-forge/conda-forge-ci-setup-feedstock#256 should fix it.

Phew! I thought we were going crazy here 😄
