1. Problem description
When I compile, I get an error symbol(s) not found for architecture x86_64.
2. Solution
The reason is that the computer is an ARM architecture (Mac with M1 chip), and the specified library is downloaded under the x86 architecture.
So I reused arm's homebrew (I named it abrew to distinguish it from x86's ibrew), downloaded the relevant libraries and specified the path to the netcdf-fortran library, and then recompiled.
abrew install netcdf-fortranThe homebrewde installation path of arm is different from the installation path of x86, which is located under /opt/homebrew/
/opt/homebrew/Cellar/netcdf-fortran/4.6.0/
