[Libmesh-users] Configure questions on a Debian woody and compiling examples

[Leopold P. A. <le...@wo...>]

Hi,

finally I have compiled libmesh on a debian woody system. Ok, thank's a lot 
for the help. Finally was had a directory WITHOUT spaces and some enviroment 
variables. So these are the steps:

To compile libmesh with MPI and PETSC you need these packages.

mpich
petsc2.1.3-dev

Also:
graphviz (non free section, for graphics in documentation)

$export PETSC_DIR="/usr/lib/petsc"
$export PETSC_ARCH="linux"
$./configure

This will create the library. About the examples I have found some problems. 
First of all you need some extra package, zlib1g-dev. Because you cannot 
compile the example 1. The error is:

/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status

Sadly, the rest of the examples cannot be compiled, because some error (see 
below). I have found in the net about the mktemp and mkstemp question, but I 
understand that it's just a warning. About the undefined references in XXXX I 
have found that is a compiler error, but in the arm architecture not i386 
(gcc 2.95)

Please, could someone confirm this?
