Paula Antoshechkina at Caltech has kindly built the latest version of MELTS/pMELTS and rhyolite-MELTS (v. 1.0.2) for Ubuntu in both 32-bit and 64-bit versions. These Ubuntu versions of MELTS/pMELTS are code-identical to the latest Mac OS builds. The Ubuntu executables are zip-compressed and downloadable:

Consult MELTS for Mac OS X for additional information about rhyolite-MELTS, including instruction on how to cite model results.
