Hi @testpilot,
please try to follow the forum guidelines and format your post accordingly.
You’re more likely to get relevant advice if you present the lammps version your using, how it was compiled, where the error appears and if it still does with some minimal example (i.e. not your production run script).
As this appears to be an error related to the call of fft library, check for the installation and compilation of the LAMMPS executable you’re using with the people in charge if necessary.
