[ncl-install] question about ncargf90

[Kevin Hallock]

Hi Jerry,

The “ncargf90” script has the Fortran compiler used to build NCL hardcoded into it. Unfortunately, the $FC (Fortran Compiler) environment variable used by the conda build system includes the full path to the compiler from the build environment, and as you discovered this path does not exist on your system.

A workaround that you can use instead is to edit line 26 of the /root/.conda/envs/ncl_stable/bin/ncargf90 script to be just:
set fortran  = "gfortran"

which will cause ncargf90 to use the first “gfortran” program it can find in your $PATH environment variable.

If you want to use the same compiler that NCL was built with (“x86_64-conda_cos6-linux-gnu-gfortran”), you can install the gfortran package on conda:
conda install -n ncl_stable -c conda-forge gfortran_linux-64    # or gfortran_osx-64 on Mac

and then edit line 26 of the ncargf90 script to be:
set fortran  = "/root/.conda/envs/ncl_stable/bin/x86_64-conda_cos6-linux-gnu-gfortran"

I hope this helps,
Kevin

>     the system is centos 7 x64, ncl version is 6.6.2 installed with 'conda', I also add the $NCARG_ROOT to the 'path'. I can run the command of NCL such as ncl_convert2nc successfully. could you give me some suggestions? Thanks in advance.
