[geos-devel] Computational Geometry Problem + Exception (Mateusz Loskot)

[Jo]

Hi,
Just to let you know, the problem I had, was related to the fact that my
gdal libraries were compiled with an older version of geos.
So I had:
- geos-svn installed from source;
- gdal installed from an Ubuntu package, with a previous version of geos.

So the solution would be, either to have everything installed from
(compatible) packages, or everything installed from source.
As I am a Slackware user, I went to the second one :-)
So:
- compile and install geos from svn (that was done!)
- recompile gdal to pick up the latest geos version (which involved not only
a configure, but also a clean) and install it;

And it's working! :-)
                                         Jo
