How to install mopac 2022 in Rocky (RHL) 9 #113

I am testing computational chem programs in Rocky Linux 9 (derived from Red Hat Linux 9). MOPAC2016 installs and runs fine, as do G16 and ORCA5.

How do you run mopac installed in this fashion? |

I may be overestimating and overstating the support of QT-based installers by major Linux distributions - I will revise language on the website accordingly with the next release. As Susi noted, MOPAC is now available through Linux package managers (Fedora and Conda so far), so incompatibilities with QT should not be a barrier for easy access to MOPAC. The standard output file for MOPAC is |

If EPEL is already enabled on your system, all you need to do is
# dnf install mopac
