Hi Matt, I think you'll want the second one as the third only provides a patch for one specific file. If you need the better handling of spikes then do svn revert include/mapnik.ctrans.hpp then apply the third patch on top of the previously patched code. I just tested and it seems to apply fine against Mapnik 0.7.1: svn co http://svn.mapnik.org/tags/release-0.7.1 cd release-0.7.1 wget http://trac.mapnik.org/raw-attachment/ticket/180/offset-0.7.0.patch patch -p0 < offset-0.7.0.patch svn revert include/mapnik/ctrans.hpp wget http://trac.mapnik.org/raw-attachment/ticket/180/sharp_spike_fix.patch patch -p0 < sharp_spike_fix.patch If you get this far and it builds fine, please do: svn diff > mapnik0.7.1-offsets.patch and re-post that to trac.
