PETSc

[ErkinYildiz]

Dear community

after having solved the Trilinos issue, deal.ii works just fine. However, all examples that involve PETSc cannot run, of course,
since deal.ii was configured with the option DEAL_II_WITH_PETSC = OFF

I did attempt at installing PETSc through Candi, with the following outcome:

---

candi tries now to download, configure, build and install:

Project: deal.II-toolchain

Platform: deal.II-toolchain/platforms/supported/macos.platform

Either run ./configure with --with-shared-libraries=0 or use a different BLAS/LAPACK library

I could indeed figure out that home-brew openblas is present at /opt/homebrew/opt/openblas and the error message suggests what should be done
./configure with --with-shared-libraries=0
but I cannot see how and where I should use such a command. Any help appreciated.

What kind of system are you on? ARM or x64?

What are your compilers mpicxx -v, mpicc -v?

How are you running candi?

[ErkinYildiz]

I am using the ARM system.

erkinyildiz@Erkins-MacBook-Pro ~ % mpicxx -v
Apple clang version 14.0.0 (clang-1400.0.29.202)
Target: arm64-apple-darwin22.2.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

erkinyildiz@Erkins-MacBook-Pro ~ % mpicc -v

I am running Candi
After brewing

brew install cmake open-mpi gcc@11
deal.ii has been installed according to

git clone https://github.com/dealii/candi
cd candi
./candi.sh -j 8 --packages="hdf5 p4est trilinos dealii"

[tjhei]

Can you use the updated instructions at https://github.com/dealii/dealii/wiki/Apple-ARM-M1-OSX
(see the brew install --cc=clang ... line)? You probably need to start over (not sure how to delete all brew packages)

[ErkinYildiz]

Hi Timo, after I started over from the scratch and used the command that you suggested me, I got an error in this way.
