Re: [deal.II] Error installing with Candi

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? Include /Users/davidryan/deal.ii-candi/tmp/

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 ad
