This is an old email but since it was never answered: I believe this has to do with the fact that you installed MPI in your homedir and then probably updated the operating system afterwards, right? If true then you'll probably have to re-install MPI with the updated operating system.

Hi everyone,

I changed my computer just a few days ago and I am re-installing dealii
on the new one. The computer is running Ubuntu 11.10 64bit. I want to
use p4est and I follow the installation guide for p4est in the README,
that is using the p4est-setup.sh. After downloaded the 0.3.3.8 package
of p4est I ran the p4est-setup.sh and get the following error message:

==========error message=============
Build FAST version in /home/huyaoyu/Libraries/p4est-build/FAST
/usr/bin/ld:

==========end of message===========

I tried to change the p4est-setup.sh at the following line into:

export CFLAGS_FAST="-O2 -fPIC"

Ran p4est-setup.sh again and got the same error.

I changed the Makefile in p4est-build/FAST/ manually at the line into:

LDFLAGS = -fPIC

Same error again.

I check the make.output file in the p4est-build/FAST/ directory to see
if the additional compile and link flags are there. And they a actually
in the lines they should be.
I think it may have something to do with my MPICH2 setup cause I
compiled MPICH2 myself and made symbolic link in /usr/bin for mpicc,
mpif90, etc, substituting the original ones.

Thanks in advance.
