Hello,

I'm trying to get deal.ii installed using candi on my Mac running macOS Mojave.

Everything seems to work up till the deal.ii compiling where it tells me that it can't find the lapack libraries.

I've tried installing lapack through brew and from the website, but the installations can't seem to find the lapack libraries.

Is there anybody who has had this problem or knows how to resolve it?

===

The error that I get is as follows:

In your candi installation file, does it say DEAL_II_WITH_LAPACK=ON? Can you
set it to =OFF?

Can you verify where brew installed your lapack library? I'm not familiar with macOS, but at least you can query which files have been installed by a package via linux repository managers. I assume you can do something similar with brew as well.

-- LAPACK_LIBRARIES: *** Required variable "_lapack_libraries" empty ***

I assume the "_lapack_libraries" variable should have been set by candi at some stage?

I'm not using candi either, but maybe there is a way to tell candi where lapack is installed. Probably in a similar way as Wolfgang proposed.

Hope this helps...

Hi Marc,

Brew installs Lapack into /usr/local/Cellar/lapack/3.8.0_2.

If tried adding either the LAPCK_DIR, or the -DLAPACK_DIR to the deal_confopts, that didn't work though,

#Choose configuration and components of deal.II

DEAL_CONFOPTS="-DLAPACK_DIR=/usr/local/Cellar/lapack/3.8.0_2"

I tried adding it lower in the cfg file which also didn't work.

# Do you want to use MKL?

MKL=OFF

# MKL_DIR=

# BLAS_DIR=

# LAPACK_DIR=

Thank you for your input. I really appreciate it.

Bye!

David

Line 676 of the Candi.sh lets you skip packages.

This didn't help for me. I deleted cake and reinstalled it through brew and that fixed the problem for me.

However, Now I've run into another problem. Would anybody know why it's giving me this error?

Dear David,

sorry, macOS Mojave (and further Catalina) do not have candi support - there is something strange happening

in the recent past with the base compilers and homebrew installed mpi compilers.

(I had a similar problem as you reported)

Currently I recommend to install the deal.II toolchain in a virtual linux environment under macOS.

Best

Indeed, but one should not go directly there, use "skip:" in front of a package

in the configuration file to simply touch it.

Hi,

That's unfortunate.

Thank you for the reply

Bye!
