Re: [deal.II] dealii installation issues on Intel Mac

[Luca Heltai]

The fix for this is quite simple, actually. You don’t have to recompile anything. It is enough to replace che path of the compiler inside the cmake file.  Modify $(spack location -i dealii)/lib/share/cmake/deal.II/deal.IIConfig.cmake, around lines 109/110     set(DEAL_II_CXX_COMPILER "/spack/lib/spack/env/gcc/g++")     set(DEAL_II_C_COMPILER "/spack/lib/spack/env/gcc/gcc") must become     set(DEAL_II_CXX_COMPILER "/Applications/deal.II.app/Contents/Resources/Libraries/bin/mpicxx")     set(DEAL_II_C_COMPILER "/Applications/deal.II.app/Contents/Resources/Libraries/bin/mpicc") Luca Il giorno 18 set 2024, alle ore 15:56, 'Alexander Greiner' via deal.II User Group <dealii@googlegroups.com> ha scritto: Dear all, after updating my Intel Mac to  Sonoma 14.6.1 Xcode 15.4 xcode-select version 2408 AppleClang 15.0.0 I have problems reinstalling deal.II. I tried the https://github.com/dealii/dealii/releases/download/v9.5.2/dealii-9.5.2-sonoma-intel.dmg package ending up in cmake errors (attached) and discussed also here (https://groups.google.com/g/dealii/c/2hQ_pqbejgM). I tried ccmake to set the correct compiler which leads to a successful run of cmake, but make then leads to linker errors. I also painfully managed to install the current dealii master version directly via spack, essentially leading to the same cmake problems. I also tried using candi (as it recently worked successfully on a Mac with M3 processor) - also without success. I highly appreciate any tips, tricks and magic to install a recent version of deal.II.
