[OSM-dev] Mapnik installation errors

[Scott Pezanowski]

Hi Dane and Stephan,

I just wanted to follow up on my resolution. I looked at the link Stephan had sent for the various installations of Mapnik. The temptation was too great to simply use a machine with Fedora on it and install from the Fedora repository. I did try once to get my RedHat machine to compile Mapnik and Boost with the same version of the Python headers. This did not work on first try, so I took the easy route of going to Fedora. So, I now have a working Mapnik install and I seem to be generating my map tiles without any further issues.

Thank you both for your assistance.

Scott

Hi Scott,
The error you are seeing is related to Boost.Python, and you'll likely need to recompile the 'boost_python' library before continuing to try to install Mapnik.
Essentially what is happening is that boost python is compiling against different python development headers than the library is linking to. For example, when you built boost python it likely compiled against python2.3 headers but is linking at runtime to python24.
The other possibility is that you don't even have the python2.4 development headers installed, which you should confirm that you do...

I have been struggling for a while to install Mapnik. I am hoping someone can point me in the right direction for why I am getting the errors I am getting. Or, can someone perhaps point me to a different way to install Mapnik, if possible (an RPM maybe?). If I am posting in the incorrect place, can you let me know a better place.

My environment is RedHat Linux ES 5, with boost 1.42 installed from source, python 2.4, and mapnik 0.7.0. 


I just compiled fine on Centos 5.4 the other day, so this setup should work fine.
The only trick that helped was making sure that 'usr/local/lib' was in ld.so.conf BEFORE compiling mapnik and after installing boost, so that the library was found correctly.
sudo bash -c "echo '/usr/local/lib' > /etc/ld.so.conf.d/local.conf"sudo /sbin/ldconfig

I configure Mapnik with this command:

python scons/scons.py configure INPUT_PLUGINS=all OPTIMIZATION=3 SYSTEM_FONTS=/usr/share/fonts/truetype/ttf-dejavu BINDINGS=python

Things look good when I configure, but when I then run this command:  python scons/scons.py - I get these errors below (please let me know if you need more of the output):

So, please go back and re-build the boost python library and this should be fixed. You can try something like:
cd boost_sources./bootstrap.sh./bjam --with-python python=2.4 -a  toolset=gcc stage -d2cp stage/lib/libboost_python.so* /usr/local/lib/
** Note, the -d2 will prompt boost to print the actual commands it sends to gcc. Make sure their is no paths to another python version that appear. If there are then I can suggest a more definite way to get bjam/boost to compile against the right python version, by using a special bjam config like described here:
