Hi Timo,
I tried another compilation and installation of deal.ii without PETSC,
P4EST and LAPACK(by setting the corresponding
DEAL_II_WITH_PACKAGENAME=OFF). After successfully completing installation I
tried the examples step-1 and step-2 with *cmake . ; make ; make run*, and
both of them
Hi Timo,
Thank you for your suggestion. I repeated the installation process and
this time I didn't run the quick_tests. Rather I changed to examples/step-1
directory in the deal.ii installation and executed the following :
*cmake . *
*make *
which exited with the following error :

Running the tests seems to have triggered a rebuild of deal.iII. Can you
try running some of the tutorial steps instead?
