Dear Gerald,
It does not seem like an out-of-memory error since the compilation of p4est
is clearly not a memory intensive operation (it's only C after all).
Looking at your error log, this seems to be where compilation crashed:
In file included from
/home/gerald/bin/dealii-candi/tmp/unpack/p4est-2.3.6/sc/src/sc_dmatrix.h:32,

What I would look into are the following:
- Did you install all of the recommended dependencies from Candi before
proceeding with the installation? It seems as if you do not have an
installation of BLAS on your computer, which would prevent p4est from
actually compiling.
- If BLAS is indeed installed correctly, then I would try to install a more
recent version of p4est. This could be achieved my changing the version and
the checksum in the deal.II-toolchain/packages/p4est.package file.
However, from what it seems right now is that you are missing a BLAS
library on your computer.
Don't hesitate if you have more questions
Cheers
BB
