I tried to reinstall the deal ii but again give the same error how can fix it
Error! This tutorial requires a deal.II library that was configured with
the following options:
DEAL_II_WITH_UMFPACK = ON
However, the deal.II library found at /home/hussan/deal was configured with
these options:
DEAL_II_WITH_UMFPACK = OFF
Hussan:
when you configure deal.II with cmake, it shows a summary of configuration
options at the end. Can you copy-paste that into an email and also attach the
file detailed.log that cmake produces?
In the end, cmake probes the properties of your system and decides that (i) it
cannot find a version of UMFPACK on your system, (ii) it also cannot find the
necessary requirements to build its own version of UMFPACK. The latter
typically happens if your system does not have BLAS and LAPACK installed. You
may want to install these packages through the Ubuntu package manager.
