Dear User Group, I recently got a new Apple arm-based M4 laptop running Mac OS Sequoia. My previous laptop was running Windows and using the Windows Subsystem for Linux, I managed to install deal.ii together with all the packages I would like to use.
Now, I tried to install deal.II on the new machine. I followed the guidlines here: https://github.com/dealii/dealii/wiki/Apple-ARM-M1-OSX and everything went perfectly fine except for a small but for me important detail. Deal.II couldn't be configured to use MueLu from Trilinos. MueLu was installed but the corresponding *error* message from candi_configure.log when running configure_20_trilinos.cmake shows that the support was disabled because the test didn't succeed. -- Performing Test TRILINOS_MUELU_IS_FUNCTIONAL -- Performing Test TRILINOS_MUELU_IS_FUNCTIONAL - Failed -- MueLu was found but is not usable through Epetra! Disabling MueLu support. I tried several other ways: - Docker: I also got the same error (i.e. module TrilinosWrappers::PreconditionAMGMueLu not defined) probably because of defined(DEAL_II_TRILINOS_WITH_MUELU) being false in trilinos_precondition.h when I used the most recent docker image for the arm based architecture. - prepackaged .dmg files (v9.6.0 sequoia arm) --> same thing - prepackaged .dmg files (v9.5.0 intel) --> also tried this with the hope that maybe in a Rosetta2 emulated terminal, this could work but got the same error and even more like this:*/Applications/deal.II.app/Contents/Resources/Libraries/include/boost/container_hash/hash.hpp:132:33: **error: **no template named 'unary_function' in namespace 'std'; did you mean '__unary_function'? *132 | struct hash_base : std::unary_function<T, std::size_t> {}; Therefore I have two questions: 1. Do you see a way to fix the above, i.e. get the MueLu support working. 2. What would be a *brute force* way to get deal.ii working on an arm-based machine. Should I try to run the terminal under Rosetta2 emulation and try to install from source? Thank you very much in advance for your help and best regards, Nik -- 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.
