00:55:07 <twain47> finally - got trunc working with renderd and everything works
00:55:47 <twain47> was wondering about adding a legacy.hpp to mapnik with some #defines to make the transition easier.  Would that make sense?
01:05:54 <springmeyer> twain47: great news!
01:06:37 <springmeyer> twain47: sounds like a good idea to me, good to runn by artem tomorrow

05:40:30 <jeffwheeler> I'm having a lot of trouble finding the right tool for my job. I have a shapefile with a bunch of features in it (a few thousand bus stops) that I can read and draw nicely in mapnik, but I think I need a separate tool altogether to find the closest stop given a GPS position.
05:41:48 <jeffwheeler> If I understand it correctly, mapnik doesn't do this --- it's just for drawing --- but I'm having trouble finding the right tool.
05:49:27 <racicot> jeffwheeler: postgis will have that capability ... would require getting your data into the database...

10:13:44 <Dominic236> Hello
10:14:23 <Dominic236> is there someone out there who has a clue about running Mapnik on Suse Linux Enterprise 10 SP2, 64 Bit?
10:15:35 <Dominic236> after compiling ICU and boost (with regex using ICU support) I tried importing mapnik with python and got the following error:

14:37:00 <Dominic236> someone out there who has experience with Mapnik running on Suse Linux Enterprise Server?
14:50:07 <Ldp__> Dominic236: no specific experience, but what are you encountering?
15:02:53 *** ajturner has quit ()
15:07:14 <Dominic236> Ldp__: I m getting a "ImportError: /usr/local/lib64/libmapnik.so.0.8: undefined symbol: png_get_asm_flagmask"
15:07:34 <Dominic236> when I try to import mapnik with python
15:07:45 <Ldp__> that sounds familiar, but I don't know if it was resolved
15:08:18 <Ldp__> do you have a need for mapnik trunk? most users would want to stay on the 0.7 branch for now
15:08:45 <Dominic236> i already tried with branch version... same thing...
15:09:02 <Ldp__> the 0.7 branch should not give a libmapnik.so.0.8
15:09:18 <Dominic236> true... it was the same with ...so.06
15:10:02 <Dominic236> right now I updated to python 2.5, currently rebuilding mapnik...
15:10:05 <Ldp__> png_get_asm_flagmask sounds like you need (an update to) libpng-devel ?
15:10:13 <Ldp__> why not python 2.6?
15:10:36 <Dominic236> can t find it for SLES 10...
15:10:59 <Dominic236> I got libpng version 1.2.8-19.25

15:44:53 <artem> Dominic236: I'm back :) let me have a look at png_io source ..
15:45:36 <artem> #if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200) && defined(PNG_MMX_CODE_SUPPORTED)
15:45:36 <artem>       png_uint_32 mask, flags;

15:45:37 <artem> #endif
15:46:01 <Dominic236> I know, I ve seen that...
15:46:34 <Dominic236> for me it looks like this error is telling me that for some stupid reason this function is available
15:46:34 <Dominic236> in that library version I am using...
15:47:23 <Dominic236> Does (PNG_LIBPNG_VER >= 10200) mean that you need version 1.02 or higher?
15:47:24 <artem> I'm pretty sure you have multiple incompatible libpng on your system. I'
15:47:31 <artem> 1.2
15:47:40 <Dominic236> cuz I got 1.2.8-19.25 running..
15:48:13 <Dominic236> I got libpng for 32 and for 64 Bits, both ver 1.2.8-19.25
15:48:33 <Dominic236> while compiling mapnik, I it with both, 32 and 64
15:48:35 <artem> Are building 64 or 32 Mapnik ?
15:48:51 <Dominic236> how can I trigger this?
15:49:07 <artem> ok, what to you get from :
15:49:10 <artem> uname -a
15:49:16 <artem> and gcc -v
15:49:38 <Dominic236> uname -a = Linux dbsosm 2.6.16.60-0.42.8-smp #1 SMP Tue Dec 15 17:28:00 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux
15:49:38 <nikq> Ticket #1: no such ticket. (list index out of range)
15:50:14 <Dominic236> gcc -v= Target: x86_64-suse-linux
15:50:34 <artem> excellent, you're building 64-bit binaries
15:50:47 <Dominic236> that s what i thought...
15:51:44 <artem> Could you locate all libpng's on your system ?
15:52:16 <artem> try : locate libpng
15:53:37 <Dominic236> ok, some are located in /usr/lib/ and some are in /usr/lib64, both directories show the same file version...
15:54:37 <Dominic236> "find ..." gives me the same, but also finds libpng in /usr/share as well as in /usr/include
15:54:39 <artem> I assume you have 64-bit binaries in /usr/lib64 and 32-bit in /usr/lib - this is common convetion
15:54:47 <Dominic236> yep
15:55:13 <artem> good, now see the output from :
15:55:50 <artem> nm /usr/lib64/libpng.so  | grep ' png_get_asm_flagmask'
15:56:23 <Dominic236> says: nm: /usr/lib64/libpng.so: no symbols
15:56:59 <artem> alright, they must've been stripped ..
15:57:48 <Dominic236> ok... so how do I get a "non-stripped" version? Weird...
15:57:53 <artem> what about nm /usr/lib/libpng.so  | grep ' png_get_asm_flagmask'
15:58:26 <Dominic236> just tried...same
15:58:39 <Dominic236> also tried with libpng12.so ...
16:01:14 <artem> You need to ensure you're using libpng12.so from /usr/lib64 when building and running Mapnik
16:02:15 <Dominic236> I did with option "PNG_LIBS=/usr/lib" while compiling
16:02:31 <artem> ok, it should be /usr/lib64 right ?
16:02:43 <Dominic236> yeah, that s what I meant
16:04:13 <Dominic236> python
16:04:17 <Dominic236> damn it , sorry
16:04:47 <artem> ok, and do you get from :
16:05:05 <artem> ldd libmapnik.so.0.8.0 | grep libpng
16:05:17 <artem> what do you get ?
16:06:54 <Dominic236> I get: libpng.so.3 => /usr/lib64/libpng.so.3 (0x00002b9a0f9d9000)
16:07:37 <artem> right, looks good to me
16:08:08 <Dominic236> i know... ;-)
16:08:10 <artem> I suggest you comment out that asm optimization block and rebuild
16:08:28 <artem> #if 0   .... #endf
16:09:04 <Dominic236> within that, em, how was that file called again?

16:21:45 <springmeyer> artem: you bet
16:21:53 <springmeyer> thanks so much for taking a look
16:22:51 <artem> no probs, I'm surprised m points gone missing for so long
16:23:13 <artem> Dominic236: looks ok to me, just to be sure :
16:23:21 <artem> ./scons/scons.py -c
16:23:30 <artem> ./scons/scons.py install
16:24:08 * artem start thinking that SUSE has got buggy libpng hmm. 
16:24:49 <artem> Dominic236: if after cleaning it's still not working lets build libpng from source !
16:25:15 <Dominic236> ok, it s rebuilding now...
16:25:41 <Dominic236> do you have an address where I can get libpng source?
16:26:54 <Dominic236> nevermind, got from sourcforge
16:27:03 <Dominic236> version 1.4.0
16:27:57 <artem> Dominic install libpng somewhere other than /usr/ e,g  /opt/libpng
16:28:18 <artem> ./configure --prefix=/opt/libpng  && make && make install
16:28:21 <Dominic236> haha, I was just about to do that! ;-)
16:30:01 <Dominic236> artem: I m sorry, unfortunately, I gotta go... do you think we can continue tomorrow?
16:30:31 *** ajturner has quit ()
16:30:42 <Dominic236> I ll let it rebuilt, see what I get and if it doesn t help, I ll install libpng from source and then compile Mapnik with this one...

16:31:07 <Dominic236> I know... that where I got to know artem! ;-)

17:01:11 <springmeyer> I have a loaner laptop from a client that has arcgis
17:01:15 <springmeyer> sure
17:01:57 <artem> Ideally if you can use your original multipoint dataset and just add M and Z, that would awesome
17:02:00 <artem> be
17:02:19 <springmeyer> okay, I'll look into that
17:02:50 <artem> no hurry, but it would be worth testing before 0.7
17:05:35 <springmeyer> okay. Just debugging some permissions wierdness with the osx packages

17:30:34 <springmeyer> also, try with that "polyline" shapefile I emailed to you
17:30:34 <artem> ok
17:30:34 <springmeyer> its not multipoint but gets hung in that same spot
17:30:34 <springmeyer> good call on ogr and sqlite
17:30:34 <springmeyer> ogr is suitable for now, I've not looked at sqlite
17:30:43 <artem> as contributions are growing , we should consider a proper code review for 0.8.0
17:31:04 * springmeyer nods
17:31:12 <artem> btw, is anyone using Oracle plug-in ?
17:31:24 <artem> I haven't tried it myself yet
17:31:40 <springmeyer> I've not either
17:32:08 <springmeyer> I've seen just one email on mapnik-users of someone trying to get it running
17:32:08 <artem> ok, I guess 'experimental'  status says it all
17:32:44 <springmeyer> it does lead to confusion for some installing from source
17:33:09 <springmeyer> but i just added some hint text for depedencies not found that should help with that
17:33:10 <artem> d'you mean scons print out in red ?
17:33:19 <artem> yellow
17:33:29 <springmeyer> well, scons previous, ya, yellow, just the library name

21:04:44 <artem> is this is correct extent for multipointz ?
21:05:28 <artem> Did you make it out of (-180,-90,180,90) intentionally ?
21:05:49 <springmeyer> heh
21:05:51 <springmeyer> no
21:06:03 <springmeyer> yes that looks like the right bounds
21:06:06 <springmeyer> sorry about that
21:06:16 <artem> no probs just want it to make sure

21:08:10 <springmeyer> good question
21:08:30 <springmeyer> last time I actually used arc for anything substantial I'd never heard of such a projection
21:08:35 <springmeyer> so, I'll have to check :)
21:10:52 <artem> does curveball have 'm' in multipointz - apparently 'm'  is optional for multi***z geometries ?
21:11:23 <springmeyer> say again?
21:11:30 <artem> I'll try :)

22:17:45 <artem> springmeyer: where did you get 'polylines.shp' ?
22:18:18 <springmeyer> I added it to the testing data a while ago
22:18:28 <springmeyer> original drawn by warren for line offsets tests
22:18:40 <springmeyer> then yesterday I added a text column in QGIS
22:18:59 <artem> ok, tnx
22:19:05 <springmeyer> and added various testing text supposed to be edge cases
22:19:28 <springmeyer> it seems it is some of the odd text characters that triggered the unhandled loop...
22:19:57 <artem> any chance to have original one ? without edge cases ? to test geometry first
22:20:05 * springmeyer is still battling osx installer issues trying to get it ready for release
22:20:16 <springmeyer> artem: yes, its in mapnik/tests/data/shp
22:20:16 <artem> ok, no probs
22:20:21 <artem> ha
22:20:25 <artem> cheers :D

22:58:56 <myselfhimself> hi
22:59:14 <myselfhimself> I need help with using quantumnik with a remote postgis db
22:59:28 <myselfhimself> I have python errors in a poping up window
22:59:38 <myselfhimself> first of all
22:59:40 <springmeyer> http://dpaste.com
22:59:44 <myselfhimself> what I kind of layer should I create
22:59:50 <myselfhimself> thanks springmeyer you're awesome
23:00:04 <myselfhimself> should I create a vector layer as in the first screencast ?
23:00:09 <myselfhimself> or a postgis layer ?
23:00:33 <springmeyer> what are you trying to do?
23:02:06 <myselfhimself> I have a postgis layer on a remote server
23:02:42 <myselfhimself> I want to create a mapnik xml "stylesheet" files for the symbols that this postgis layer contains
23:02:53 <myselfhimself> I think that quantumnik will help me do that
23:03:02 <springmeyer> okay, yes
23:03:06 <myselfhimself> : )
23:03:12 <springmeyer> Menu > Layer > Add Postgis Layer
23:03:48 <springmeyer> New, then select it, then Connect...
23:04:14 <myselfhimself> ok
23:04:17 <myselfhimself> this works
23:04:19 <myselfhimself> test connect works
23:04:37 <myselfhimself> and when I click ok I manage to see a map of my building (since I work on indoor mapping)

23:06:34 <springmeyer> myselfhimself: just start with one layer...
23:06:40 <myselfhimself> ok
23:06:40 <springmeyer> make sure Mapnik can render it...

23:08:14 <myselfhimself> jaunty's official mapnik is 0.5 so I removed it first when I realised that
23:08:43 <springmeyer> sure
23:08:44 <myselfhimself> ok in the Mapnik Rendered Map tab which's appeared, I see nothing just white
23:08:57 <springmeyer> did you get a projection warning?
23:09:01 <myselfhimself> no
23:09:06 <myselfhimself> no dialog popped up
23:09:10 <springmeyer> okay
23:09:12 <springmeyer> not good
23:09:15 <myselfhimself> maybe I can see something in a shell
23:09:30 <myselfhimself> I click on "Zoom full" an still see nothing

23:10:55 <myselfhimself> http://dpaste.com/144881/ thanks !!
23:12:51 <myselfhimself> do you want the server's IP ?
23:13:12 <springmeyer> ya, let me see if I can connect
23:13:15 <myselfhimself> : )
23:13:21 <springmeyer> pm me ?
23:13:36 <myselfhimself> ok
23:13:43 <artem> springmeyer: multipoints are fixed, lets move to dodgy polylines - any ideas why polylines.shp in infinite_loop_problem.zip is different from  one in tests/data/shp . I can see you added text attributes but geometries should stay the same ??
23:14:00 <springmeyer> artem: yes, just text changed
23:14:40 <artem> yes but *.shp are different - I guess qgis did something ..
23:15:00 <artem> hmm..
23:15:04 <myselfhimself> thanks springmeyer !
23:15:10 <springmeyer> certainly possible that QGIS borked it when it edited the dbf
23:15:25 * springmeyer tries converting/copying shapefile with ogr2ogr to check that
23:15:37 <artem> which qgis version are you using ?
23:15:53 <myselfhimself> artem: me ?
23:15:54 <springmeyer> solved!
23:16:08 <springmeyer> artem: converting with ogr2ogr fixes infinite loop
23:16:27 <artem> hmm.. dodgy dodgy ..
23:16:28 <springmeyer> so likely QGIS is doing something fishy
23:16:30 <myselfhimself> sorry I was mixed up in the conversation
23:16:41 <springmeyer> QGIS 1.4 latest release from a few days ago
23:17:21 <springmeyer> great, so lets not worry about that then huh?
23:17:25 <springmeyer> certainly would be nice to exit out if there were a problem though...
23:17:30 <artem> myselfhimself: no probs.
23:17:36 <artem> springmeyer: yes, sure
23:19:11 <artem> springmeyer: I though qgis is using ogr/gdal to read/write shapefiles ??
23:19:14 <artem> thought
23:19:41 <springmeyer> artem: that is what I would guess too, but I'm not sure
23:20:16 <springmeyer> myselfhimself: that data from your server loads fine for me
23:20:23 <springmeyer> what Quantumnik version are you using?
23:20:26 <myselfhimself> ok
23:20:27 <springmeyer> and QGIS version?
23:20:51 <myselfhimself> I'm using 174.129.8.111
23:20:53 <myselfhimself> sorry
23:21:06 <springmeyer> oh?
23:21:11 <myselfhimself> qgis 1.40 enceladus
23:21:20 <myselfhimself> I downloaded it just today from a ppa
23:21:22 <springmeyer> okay
23:21:23 <myselfhimself> I think
23:21:25 <springmeyer> sure
23:21:30 <myselfhimself> and mapnik
23:21:31 <springmeyer> and Qnik version is latest too?
23:22:14 <myselfhimself> mapnik, I can't tell it's 0.6
23:22:29 <myselfhimself> this is an ubuntu ppa mapnik
23:22:35 <myselfhimself> I can have the precise version
23:22:42 <myselfhimself> I know the package dates back to 07/2009
23:23:36 <myselfhimself> 0.6.0-1ubuntu7~jaunty
23:23:46 <myselfhimself> (taken from the ppa page)
23:23:57 <myselfhimself> I can compile something from source if that's better
23:24:08 <myselfhimself> or I can run qgis from console also to see std output
23:24:58 <springmeyer> myselfhimself: Quantumnik version?
23:25:04 <myselfhimself> yes
23:25:07 <myselfhimself> ah sorry
23:25:13 <myselfhimself> the latest I'd say
23:25:18 <springmeyer> okay
23:25:20 <myselfhimself> I downloaded it from your repo today
23:25:23 <myselfhimself> tonight
23:25:25 <springmeyer> sure, thats good
23:25:38 <springmeyer> so I think I must have broken compatibility with Mapnik 0.6.x
23:25:45 <springmeyer> which is not good
23:26:03 <myselfhimself> does the rendered map show up well in your qgis for my db ?
23:26:17 <springmeyer> yes, nicely
23:26:21 <myselfhimself> ok
23:26:39 <myselfhimself> well your plugin details mention that mapnik >=0.6 is ok
23:26:39 <springmeyer> oh wait...
23:26:43 <myselfhimself> ah
23:26:43 <springmeyer> I see it
23:26:51 <springmeyer> grr QGIS
23:26:52 <springmeyer> so...
23:27:20 <myselfhimself> I'll your mapnik binary (the 0.7 you mentioned yesterday or so on this channel) or 0.8 from source
23:27:21 <springmeyer> QGIS defaults to long/lat aka WGS 84 projection
23:27:23 <springmeyer> which is EPSG:4326
23:27:25 <myselfhimself> ok
23:27:28 <springmeyer> which is not at all what OSM data is int
23:27:38 <springmeyer> see your xml: <Parameter name="srid">4326</Parameter>
23:27:42 <myselfhimself> yes
23:27:43 <springmeyer> it should likely be
23:27:48 <springmeyer> <Parameter name="srid">900913</Parameter>
23:28:02 <springmeyer> did you use standard options when importing using osm2pgsql?
23:28:06 <myselfhimself> : ))
23:28:07 <springmeyer> if so, it will be 900913
23:28:22 <springmeyer> so you have to see that Projection in QGIS for your whole project...
23:28:28 <myselfhimself> hey 4326 is xy right ?
23:28:36 <myselfhimself> ok
23:28:38 <springmeyer> the fact that QGIS cannot autodectect is lame lame lame
23:28:42 <myselfhimself> ok
23:28:58 <myselfhimself> I should put a feature request for that on their tracker maybe
23:29:16 <springmeyer> yes, certainly
23:29:30 <myselfhimself> this map I'm using comes from a rails port postgres and I have a correct .osm dump somewhere
23:29:37 <springmeyer> myselfhimself: when I add one of your layers I get a popup that says....
23:29:48 <springmeyer> "Define this layers coordinate system..."
23:29:54 <springmeyer> you don't?
23:30:23 <myselfhimself> no
23:30:34 <springmeyer> thats a problem
23:31:10 <springmeyer> what do you have under....
23:31:18 <springmeyer> Preferences >CRS ?
23:32:08 <myselfhimself> you mean settings > project properties > CRS tab ?
23:32:19 <myselfhimself> I have WGS 84 highlighted in the list
23:32:33 <springmeyer> nope, preferences
23:33:50 <myselfhimself> well I don't have a preferences button in the menus or elsewhere
23:33:53 <myselfhimself> I can't find it
23:34:04 <artem> springmeyer: shapefile writing is broken in QGIS 1.4 :
23:34:15 <artem> rec number = 1
23:34:15 <artem> content length = 92
23:34:15 <artem> offset= 100
23:34:16 <artem> rec number = -1
23:34:16 <artem> content length = -4097
23:34:16 <myselfhimself> settings > options > crs ?
23:34:16 <artem> offset= 292
23:34:18 <artem> rec number = 1559281503
23:34:20 <artem> content length = 1559281503
23:34:22 <artem> offset= -1
23:34:32 <artem> it just full of binary garbage
23:34:54 <artem> maybe worth reporting
23:34:56 <springmeyer> bummer
23:34:57 <springmeyer> okay
23:35:05 <myselfhimself> ok in settings > options > crs I had global wgs 84 set for anything by default, I have now ticked the prompt for everything instead
23:35:15 <springmeyer> myselfhimself: good
23:35:45 <springmeyer> so artem that is before and after?
23:35:47 <myselfhimself> i'm deleting the layer now and adding the postgis layer again from the server
23:36:04 <artem> original polylines.shp is correct
23:36:22 <springmeyer> myselfhimself: find the project when you are prompted by choosing "Name" then searching for "popular"
23:36:27 <springmeyer> artem: okay
23:36:50 <artem> the one from infinite loop is corrupt but can be fixed with ogr2ogr
23:37:22 <artem> nice polylines btw :)
23:37:23 <springmeyer> yep

23:45:41 <myselfhimself> with 3785 I still see nothing
23:46:03 <myselfhimself> where can I get to see quantumnik's mapnik work's output ?
23:47:21 <springmeyer> view the XML again
23:47:25 <springmeyer> you likely need to set the Map/Project projection now too

23:49:57 <springmeyer> srid=" ?
23:50:56 <Ldp__> status="on" ?
23:51:05 <springmeyer> Ldp__: so that 3785 likely won't work
23:51:18 <springmeyer> because 900913 is what is added to the geometry columns by osm2pgsql right?
23:51:37 <myselfhimself> status="1" here
23:51:41 <Ldp__> springmeyer: yes, true. So myselfhimself needs to add a custom crs for 900913
23:51:42 <myselfhimself> I can't find srid
23:51:45 <myselfhimself> ok
23:51:45 <springmeyer> postgis is likely throwing an SRID mismatch error (silently of course since we're talking Mapnik 0.6.x)
23:51:54 <myselfhimself> ok
23:58:59 <springmeyer> artem: just rebuilt 0.7. branch - nice job!
23:59:05 <springmeyer> multipoints are working great
