Xiaoni: Is there no traceback? Can you run ldd on the _geoslib.so that you are actually importing when the error occurs (presumably /usr/local/lib/python2.6/dist-packages/_geoslib.so)? That will tell you what version of the geos library you actually linked. I don't think I can be of much help here - all I can suggest is that you clean out all old versions of basemap, _geoslib.so and libgeos, then rebuild again. The fact that there are so may versions floating around increases the chance that you have a version mismatch somewhere. Also check the build output and make sure there were no errors building _geoslib.so. -Jeff > > > ------------------------------------------------------------------------ > *From:* Jeff Whitaker <jsw...@fastmail.fm> > *To:* xiaoni <wang...@yahoo.com> > *Cc:* matplotlib-users@lists.sourceforge.net > *Sent:* Wed, December 2, 2009 4:47:51 PM > *Subject:* Re: [Matplotlib-users] basemap099.4 and geos > > xiaoni wrote: > > Hello, all, > > I have some problem with basemap and geos， and can not use > Basemap。 > > In the below I list the information about basemap and geos in my > computer.
