[Matplotlib-users] basemap-0.9.8 failure, linux

[Evan M. <eva...@gm...>]

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
---------------------------------------------------------------------------
<type 'exceptions.ImportError'>           Traceback (most recent call last)

     33 # basemap data files now installed in

Yet the file, in fact a link, libgeos_c.so.1, does exist at the location
(/usr/local/lib) where it is supposed to be:

I'd appreciate any help with this.

Thanks, Evan

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
===================================================================
--- setup.py    (revision 4791)
+++ setup.py    (working copy)
@@ -90,7 +90,11 @@

extensions.append(Extension("matplotlib.toolkits.basemap._geod",deps+['src/_geod.c'],include_dirs 
= ['src'],))
 # for some reason, pickling won't work if this extension is installed
 # as "matplotlib.toolkits.basemap._geos"
-extensions.append(Extension("_geos",['src/_geos.c'],library_dirs=geos_library_dirs,include_dirs=geos_include_dirs,libraries=['geos_c','geos'])) 

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

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.
