Hello everyone,
Got the latest mapnik (checked out Wednesday night) compiled on Mac
OS X 10.5 with boost 1.37 (macports), but did encounter one or two
things not on the wiki page so thought I'd share them.
Firstly, couldn't get mapnik 0.5.1 to build, the SConscript couldn't
find the boost shared libraries, even though I gave the path and the
-mt matched. However, the SVN version worked fine.
Yes, that's my experience on 10.5 as well. I think this reinforces the
need for another release to get the recent fixes to SConscript out in
the wild.
Secondly the "+python2.5" specification when installing Boost
actually did pull in Python, and in turn, ncurses, from MacPorts -
even though I already have Python 2.5 and ncurses installed (in /
usr). It also pulled in gmake 3.81 which I also have already, though
it only seemed to need this for installing python and I could remove
it afterwards.
Interesting. The whole approach of macports pulling in its own copies
is standard practice but seems dangerous with mapnik once macports
requires another python copy. The last time I built boost from
macports (1.35) with the +python2.5 was able to link against the
system python, so it seems like they've updated the portfile with the
new versions.
Cairo and pycairo suffers from the same problem with macports. I worry
about setting up new users for the dreaded python version mismatch
error when various mapnik library dependencies are linked against both
system python and macports python, but I'm not sure about the best
solution/recommendation.
Thirdly to compile the rundemo.cpp I needed to add the option -
lboost_thread-mt to link the boost-thread library in. Didn't have to
do it for any of the other boost libraries though.
Interesting. What were the compile commands needed to built it?
Finally, to compile the OSM plugin I needed to link against all the
ICU libraries, not sure if this is a Mac specific thing (last time I
compiled it was on SuSE 10.3) or a Mapnik update - to compile the
OSM plugin I needed to modify the makefile to look like:
CXXFLAGS = `xml2-config --cflags` `freetype-config --cflags` -I/usr/
local/include/mapnik -I/opt/local/include -fPIC -g
MAPNIK_OSM_OBJ = osmparser.o osm.o osm_datasource.o osm_featureset.o
osm.input: $(MAPNIK_OSM_OBJ)
g++ -dynamiclib -o osm.input $(MAPNIK_OSM_OBJ) `xml2-config --
libs` -lmapnik -L/usr/local/lib -L/opt/local/lib -licuuc -liculx -
licule -licui18n -licuio -licudata
Awesome. I've yet to try the OSM plugin, but it looks interesting.
Perhaps we should build the optional compilation in the Sconscript?
Cheers,
Dane
Nick
