00:28:49 <rweait> springmeyer: OPTIMIZATION=3 in the configuse is for what?
00:29:15 <springmeyer> because we can :)
00:29:31 <rweait> not hardware related?
00:29:38 <springmeyer> 2 generally means go fast but where possible also make compiled stuff small
00:29:54 <springmeyer> whereas 3 is go fast at any cost of size of executable
00:30:16 <springmeyer> sometimes 3 with different compilers means different things
00:30:34 <rweait> any changes I should configure to take advantage of my multicores?
00:30:42 <springmeyer> I imagine we have default as 2 just as a conservative measure
00:30:49 <springmeyer> rweait: nope
00:30:56 <rweait> thank you!

02:37:30 <rweait> still trying to install mapnik2, and failing.
02:37:47 <springmeyer> ruh roh
02:37:52 <springmeyer> rweait: what is happening?
02:38:11 <rweait> ImportError: libmapnik.so.0.6: cannot open shared object file: No such file or directory
02:38:26 <springmeyer> sudo ldconfig
02:38:29 <springmeyer> then try again?
02:38:35 <rweait> done.
02:38:39 <rweait> /usr/local/lib64/libmapnik.so
02:39:04 <springmeyer> ah, rm that
02:39:16 <springmeyer> that's likely an old one too...
02:39:54 <rweait> no, I cleared it out before trying again.
02:39:59 <rweait> it's from mapnik2
02:40:10 <springmeyer> oh? hmm
02:40:43 <springmeyer> should not be...
02:40:49 <springmeyer> rweait: what does this give?
02:41:05 <springmeyer> python -c "import platform;print platform.dist()[0]"
02:41:17 <rweait> Ubuntu
02:42:14 <springmeyer> hmm, thats right
02:42:25 <springmeyer> so after installing you have nothing in?
02:42:36 <springmeyer> ls -l /usr/local/lib/libmapnik*
02:42:53 <rweait> I just deleted that.
02:43:01 <rweait> there was :
02:43:10 <rweait> /usr/local/lib64/libmapnik.so
02:43:10 <rweait> /usr/local/lib64/libmapnik.so.0.6
02:43:10 <rweait> /usr/local/lib64/libmapnik.so.0.6.1
02:43:20 <springmeyer> ah, okay great
02:43:31 <rweait> I have logs from the configure and install
02:43:34 <springmeyer> then now re-install again and you should be set
02:43:42 <springmeyer> python scons/scons.py install
02:43:52 <rweait> sudo ...
02:43:57 <springmeyer> (that should see missing /usr/local/lib/libmapnik.*)
02:44:00 <springmeyer> yep
02:44:05 <springmeyer> and place the library back there...
02:44:10 <springmeyer> then ldconfig
02:44:15 <springmeyer> then try again?
02:46:00 <rweait> same result.
02:46:32 <rweait> /usr/local/lib64/libmapnik.so
02:46:32 <rweait> /usr/local/lib64/libmapnik.so.0.6
02:46:32 <rweait> /usr/local/lib64/libmapnik.so.0.6.1
02:47:09 <rweait> ls /usr/local/lib
02:47:10 <rweait> python2.6
02:47:16 <rweait> no mapnik
02:47:37 <springmeyer> k, you must be installing a different source check out?
02:47:43 <springmeyer> $ svn info
02:47:46 <springmeyer> what does that give?
02:48:41 <rweait> URL: http://svn.mapnik.org/branches/mapnik2
02:48:49 <rweait> revision 1654
02:48:58 <springmeyer> ah ha
02:49:01 <springmeyer> do this:
02:49:03 <rweait> oh ho!
02:49:12 <rweait> cd ..
02:49:13 <springmeyer> svn switch  http://svn.mapnik.org/trunk .
02:51:11 <rweait> updating.
02:51:33 <springmeyer> yep, mapnik2 is the real deal now :)
02:51:45 <rweait> Updated to revision 1655.
02:51:50 <rweait> one more time?

02:55:33 <springmeyer> rweait: so we need a full re-compile again now...
02:55:46 <rweait> configure is done, building now.
02:55:57 <springmeyer> cool :)
02:56:14 <rweait> So I had the wrong checkout?
02:58:19 <springmeyer> yes
02:58:48 <springmeyer> mapnik2 code was merged into trunk right before we released 0.7.0

03:10:40 <rweait> _That's_ what I'm talking about.
03:10:57 <rweait> That is one long list of deprecation warnings.
03:11:22 <rweait> and a nice image.png.
03:11:38 <rweait> Yay! Hooray for springmeyer !
03:12:35 <springmeyer> we have liftoff :)
03:13:01 <rweait> Thank you!
03:13:12 <rweait> now for some style...

03:38:44 <dkb> speaking of styles, does the order of the styles in osm.xml make a difference?
03:40:02 <springmeyer> no
03:40:09 <springmeyer> only the order of layers
03:40:15 <springmeyer> and the order styles are attached to layers
03:40:55 <dkb> ok.  That was my next question about the layers. Thanks.

16:40:19 <shoe> springmeyer, jburgess: thanks for your help yesterday.
16:40:47 <shoe> turned out my problem was a nearest-neighbor interpolation during the initial reprojection.
16:41:32 <shoe> I was resampling with fancy methods after that to no avail, because the damage was already done in the initial fast reprojection.
16:42:01 <shoe> I went back and used bilinear resampling during reprojection and it's much nicer now.
16:44:03 <shoe> btw, would this be an acceptable channel to discuss mod_tile/renderd?
16:52:45 <dkb> shoe: not that I may be able to help but I have asked questions in those areas here in the past with gracious assistance provided.

17:04:30 <springmeyer> shoe: yes
17:05:58 <shoe> I'm specifically wondering if it's possible to run multiple renderds on the same machine.

18:24:05 <shoe> I meant multiple renderds for the same tile set.
18:25:26 <shoe> there seems to be a one-to-one relationship between the mod-tile map config and the renderd instance.
