basemap-0.9.8 failure, linux

Community matplotlib-users

Hi all,

Just updated basemap from 0.9.4 to 0.9.8 on Mandriva Linux 2008. I also installed basemap-data-fullres-0.9.7. I’ve noticed there’s a couple of recent posts about problems (on Macs) with 0.9.8, the solution being to install setuptools until 0.9.9 comes along; the problem I have is similar to the posts but not the same, so I’d like to check here before proceeding with setuptools.

I installed the included geos-2.2.3, then basemap-0.9.8, then basemap-data-fullres-0.9.7
. However when I now import basemap I get:

In [1]: from matplotlib.toolkits.basemap import Basemap

I’d appreciate any help with this.

Evan: I think this is a LD_LIBRARY_PATH problem. There are two possible workarounds:

1) set the LD_LIBRARY_PATH environment variable to include /usr/local/lib, i.e.

export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"

2) edit setup.py and make the following change

currents_nbp:(basemap_svn)$ svn diff
Index: setup.py

···

===================================================================

extensions.append(Extension("matplotlib.toolkits.basemap._geod",deps+['src/_geod.c'],include_dirs = ['src'],))

-extensions.append(Extension("_geos",['src/_geos.c'],library_dirs=geos_library_dirs,include_dirs=geos_include_dirs,libraries=['geos_c','geos']))

+ runtime_library_dirs=geos_library_dirs,

then rebuild. As Eric Firing pointed out to me, adding runtime_library_dirs negates the need to set LD_LIBRARY_PATH manually. This is already done in svn, and so 0.9.9 will not require manually setting LD_LIBRARY_PATH.

HTH,

Thank you Jeff. Setting LD_LIBRARY_PATH works fine as a quick test, though that leads me to the “ImportError: No module named pkg_resources” problem that the other recent posters had. I’ll either try setuptools or wait for 0.9.9 to come out - will it be long?

Evan: Sometime next week probably, If you have svn installed, you can get the latest version that way.
