Thanks @xiaomufeng for reporting this. The proper link to the GCClassic sample environment file in the documentation is:

• https://geos-chem.readthedocs.io/en/latest/getting-started/login-env-files-gnu.html

We'll make sure to fix that.

I think I see the problem. The netCDF modules are built for the Intel Cascade Lake architecture, but you are probably using a node that is a different architecture. I would recommend adding target=x86_64 to all Spack library build commands so that they will be built without chip-specific optimizations. This is important if you are using GEOS-Chem on a cluster that has nodes of multiple chipsets. I would rebuild all of the libraries with target=x86_64 and then delete the libraries for the other chip types.

I'm sorry, according to the method you suggested, I still haven't completed the installation on my end。 Here are some of my operational procedures：

1. arch

   

2. spack find

   

3. spack install example

   

4. cmake errors

   

5. mak -j errors

@xiaomufeng: Since we have released 14.4.0, the link to the GCClassic sample environment file is now present in the "stable" documentation as well:
