[Gmsh] ImportError when import of gmshpy

[Wilfried Hortschitz]

Hallo,

I try to install gmsh with its python libraries (gmshpy). I want to use
python to mesh and extrude an existing 2D geometry (set of polylines) which
was generated with the python library shapely (
https://pypi.python.org/pypi/Shapely).

Therefore, I downloaded the package gmsh-svn-Linux64-dynamic.tgz from
http://geuz.org/gmsh/bin/Linux/ .

After extraction I run the setup script 'sudo python setup.py install' in
the 'gmshpy' sub-folder which finishes without errors (see also
http://geuz.org/pipermail/gmsh/2013/008407.html).

Thereafter, the following path was exported as described here (
http://www.geuz.org/pipermail/gmsh/2013/007782.html):

    caelinux at caelinux:~$ export LD_PRELOAD=/usr/lib/libmpi.so

This procedure was tested on my local system ubuntu 12.04 x 64 with 2.7.3
and the current image of CAELinux (
http://sourceforge.net/projects/caelinux/files/CAELinux2013/)
caelinux2013-beta1.iso (tested as live-cd with virtualbox).

Unfortunately, I ended with the following error when importing gmshpy.

When I start a ipython console and type:

#############################################################
    In [1]: import gmshpy

I get the following error message:

---------------------------------------------------------------------------

     23             finally:
     24                 fp.close()

ImportError: libGmsh.so.2.8: cannot open shared object file: No such file
or directory

Do you have any suggestions what went wrong? Do I have to link libGmsh?
Maybe you can test the package with the same live cd image
(caelinux2013-beta1.iso) or try to get in contact with the developer so
that inexperienced users could simply use the cd-image.

Thanks in advance,
Wilfried
