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
