    The -DLAMMPS_EXCEPTIONS setting can be used to activate alternative +versions of error handling inside of LAMMPS. This is useful for +external codes driving LAMMPS as a library. With this option, a +LAMMPS error does not exit the driving process. Instead, the call +stack is unwound and LAMMPS can return to the caller. The library +interface provides the lammps_has_error() and +lammps_get_last_error_message() functions which the caller can use to +detect and find out more about a LAMMPS error.

    Using one of the -DPACK_ARRAY, -DPACK_POINTER, and -DPACK_MEMCPY options can make for faster parallel FFTs (in the PPPM solver) on some platforms. The -DPACK_ARRAY setting is the default. See the
