possible error error message on "make tests"

[Ravi Kannan]

Hi all,
        I am having some problems in obtaining speedups for FEM problems; I
am not sure whether this is a problem related to the way I use MPI or due to
the slow interconnection.

       So I was wondering if there are any sample benchmark FEM problems,
which are guaranteed to give good speedups.

Thanks
Ravi

Subject: possible error error message on "make tests"




Hello,

I configure and compile successfully petsc-3.0.0-p3 with:
 ./config/configure.py  --with-blas-lib=libblas.so
 --with-lapack-lib=liblapack.so --with-dynamic=1 --with-shared=1
 --with-mpi=0
(linux-gnu-c-debug x86_64). I get this worrying "possible error" message
running the tests.

Running test examples to verify correct installation
Possible error running C/C++ src/snes/examples/tutorials/ex19 with 1

I have looked in the documentation and in the troubleshooting guide and
found nothing. What does this "possible error" mean? ie; can I ignore it
safely? I am not competent enough to understand why this happens.

Thanks.

Best,
	Toby
