Avogadro Application is the graphic user interface of Avogadro 2. Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related areas. It offers flexible rendering and a powerful plugin architecture. Managed by OpenChemistry, Avogadro 2 it is based on QT5 libraries and it is a rewrite of the old Avogadro 1.x. By default the script builds avogadroapp with shared libraries. If you want to enable the building with static libraries, pass the variable SHARED=no to the script: SHARED=no ./avogadroapp.SlackBuild (hdf5 required) Warning: the computational settings made through the Input Generator require the MoleQueue server running to submit jobs to local applications or remote HPC clusters. Since Avogadro 2 version 1.98.0, the build requires cmake at version 3.24 or greater. This version is the latest compatible with Slackware 15.0 that has cmake remained at the version 3.21.
