Hi Tobias, > I was trying to compile matplotlib basemap > (http://sourceforge.net/projects/matplotlib/files/matplotlib- > toolkits/basemap-1.0.7/) which depends on libgeos. > The compilation fails because matplotlib basemap tries to link against > "libgeos.so" but in "/usr/lib" only "libgeos-3.3.3-so" is present. > > When manually creating a link ("sudo ln -s /usr/lib/libgeos-3.3.3.so > /usr/lib/libgeos.so"), the compilation/linking works without problems. > > I think during installation this link should be created.
Creating library symlinks manuall is seldomly a good idea. libgeos-3.3.3.so is the C++ library, linking against this is discouraged. Applications should like to the C API (libgeos_c.so) which is considered stable. In de documentation for mathplotlib basemaps they document linking to the C API: " If you already have it on your system, just set the environment variable GEOS_DIR to point to the location of libgeos_c and geos_c.h (if libgeos_c is in /usr/local/lib and geos_c.h is in /usr/local/include, set GEOS_DIR to /usr/local). " See: https://github.com/matplotlib/basemap Please try the above procedure to build mathplotlibs basemap with the GEOS C API. You may need to install libgeos-c1 if it's not already installed.
