Hi, yesterday I send/receive some mail with the debian packager of libpetsc. Here is the mail. Please, look it. Best regards. Leo Pd ---------- Missatge transmès ---------- Subject: Re: Maybe a bug in libpetsc-2.1.6 Date: Dimecres 19 Novembre 2003 20:28 From: Adam C Powell IV <haz...@de...> To: Leopold Palomo Avellaneda <le...@wo...> Hello, Two things: 1. You can get woody petsc 2.1.6 (adjusted so it builds with the older mpich) by adding the following line to /etc/apt/sources.list deb http://lyre.mit.edu/~powell/debian woody math 2. Either way, MPI_LIB is not meant to have all of the mpich link flags. If you scroll further down in bmake/linux*/packages, you'll see "Location of MPE" with the MPE flags which are necessary for linking. In general, if you want to link something against PETSc, you should *not* be using variables like MPI_LIB, but variables like PETSC_MAT_LIB, PETSC_TS_LIB, etc., which include PETSC_EXTERNAL_LIB_BASIC, which in turn includes MPI, MPE if present, X11, BLAS and LAPACK, etc. If you install petsc2.1.6-doc, and unpack the src.tar.gz file with all the examples, you'll see that this is how those makefiles do things. [I've also put together a petsc.m4 which defines these things, but only if you use autoconf/automake.] If libmesh is trying to directly use MPI_LIB, then that's a bug in libmesh, due to a misunderstanding of how to link against the PETSc libraries. Also, the README.Debian in the -dev package gives the address of the "package homepage" http://lyre.mit.edu/~powell/debian.html , which among other things has a link to my aptable archive with the woody backport of PETSc 2.1.6 (mentioned above).

It's still possible there's a bug in my package, but I suspect the problem is in libmesh. Let me know if you need any further assistance. -- -Adam P.

Hi, some days ago I forward a mail from the debian mantainer of the petsc package. Have you looked it? There are some news about it? Best regards, Leo |

Please stop spamming the list(s) with this question. If someone has an answer for you, I'm sure they will post it. Otherwise, consider the answer to be effectively "no". -John |

We had a problem with the smtp server yesterday (we have had some problems last week, and this too) so I sent a message with a cc to me, but I didn't received it. The last week we lost some messages, so, I post it twice. I'm sorry for the inconvenience. > If someone has an answer for you, I'm sure they will post it. Well, I hoped some opinion. Maybe I was "innocent".
