Error about running MEGAN3.1

Hi, everyone.
I met an error while running the met2mgn program of MEGAN3.1, which was compiled by PGF90.
Here is the error msg.

…/src/MET2MGN/met2mgn: error while loading shared libraries: libgfortran.so.5: cannot open shared object file: No such file or directory

I wondered if I need to install libgfortran5? And if it is needed, why the PGF90 compiled Megan version need the gfortran libs?

Looking forward to your reply. Million thanks.
Best regards,
Cecilia

You probably need to have the whole system compiled with pgf90.

What was NetCDF compiled with, for example… ?

Are you on a system that has modules? Try loading the gcc module.

module load gcc

Yes. You are right. While I changed my environment variables (IOAPI, NETCDF, HDF5) to my classmate’s, all compiled by pgf, it worked now.
Thank you very much again!

The sentence does not work for me.

bash: module: command not found…

Anyway, thanks for your suggestion.

Dear Professor, I would like to ask a question. There are more than 20 species of bvoc CB05 mechanism generated by megan3.1, but there are not so many species falling into the air quality model. For example, there are more than 10 kinds of air quality model CB05, then do those megan species not participate in the reaction?Like ISPD species?
