Animesh,
Yes, the name are reversed. Basically what happens is that ARPACK uses a
method called shift inverse which uses the inverse of the operator you
care. In practice, this means that ARPACK is not using your matrix A but
only A^{-1} because the largest eigenvalue of A^{-1} is related to th
Hi Luca,
I installed environment-modules and currently have the following lines in
my .bash_profile:
### dealii 9.2 ###
SPACK_ROOT=/Users/alexandergreiner/spack
export PATH=$SPACK_ROOT/bin:$PATH
MODULES_HOME=$(spack location -i environment-modules)
source ${MODULES_HOME}/init/zsh
. $SPACK_ROOT/s
My suggestion is to install also environment-modules, and then use
spack load dealii
This will popolate DYLD_LIBRARY_PATH with the correct values and allows your
cmake to find all libraries.
Unfortunately, recent updates to spack have made its functionality a bit clumsy
in Mac OS...

Hi, thanks for your suggestions.
Yes, Trilinos is installed by spack and
ls `spack location -i trilinos`/lib/libmuelu*
shows me the correct paths to the libmuelu libraries.
I also enabled Full Disk Access for Terminal.app and restarted the App as
described.
Still, the libraries are not linked
No, you dont have to recompile deal.II for what I am suggesting.
I suppose that lib is installed by spack, have you checked
ls `spack location -i trilinos`/lib/libmuelu*
Not sure if this will help, but
Have you enabled Full Disk Access for Terminal.app
If not, can you enable it and try. See t
Hi Praveen,
"Stupid" question beforehand: Do I have to reinstall deal.II? If yes, you
can skip the remainder. If no, I did the following:
I added that line to my ./bash_profile opened a new terminal window and
executed
source ./bash_profile
spack load dealii
cd spack/opt/.../deal.II/examples/s
I am not sure my solution will work in your case.
I use spack view to install symlinks into /opt/spack
Then I compile deal.II myself using dependencies installed in /opt/spack
Setting DYLD path to /opt/spack/lib then works for me, otherwise I too get
those library not found errors when running
Try adding path to you spack lib, like this
export DYLD_FALLBACK_LIBRARY_PATH=/opt/spack/lib
I add this to my $HOME/.profile file.
Best

Hi Wolfgang,
at least I could not find a log file, but your hint encouraged me to find
another solution. So I ran spack with -d and -v options to print out more
information directly to the terminal. As you predicted, there was an error
(attached) that seems to be related to the ginkgo package.
