This sounds like you have compiled mapnik against mixed libraries, either different arch's (32 vs 64) or different boost python versions. If I were to guess I'd say that the python you are using is from packages, and is 32 bit, but you built boost yourself 64 bit and the boost_python library cannot find a 64 bit version of python itself at runtime (on linux boost python does not directly link to python but rather loads its symbols at runtime). Either way, you may either need to recompile boost_python or mapnik against the right python headers/libs. To help futher you should run: $ldd /usr/local/lib/libmapnik.so $ldd /usr/local/lib/libboost_python.so and do ldd on the _mapnik.so that should be sitting in the mapnik source folder here: binding/python/ > I have boost version 1.43 as well as python v > 2.6 installed. how was python installed? > I am on Centos 5 and I had no problems installing mapnik. > The only problem I have is when I try to run generate_image.py.
