Or use Spack which makes sure that only note instance of each dependency (such as MPI) is used to build deal.ii and all its dependencies: https://github.com/dealii/dealii/wiki/deal.II-in-Spack
Ps. As for the multiple MPI on the system, it’s perfectly valid idea as long as you know what you are doing, namely build a single stack of software with the same MPI. That actually applies to any dependency: you can have and try/compare as many as you want, but you need to use them consistently to build the stack. Most likely it’s not your intention here, but that’s what Spack makes easy as packages are never installed into the same prefix like /use/local Regards, Denis -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
