[mapserver-users] Problem compiling MapServer 6.0.1 with libpng
Hi, After many trials and missings, I am still unable to compile MapServer 6.0.1 (6.0.0 also) on my Debian Lenny machine. Here is the error I get: ./libmapserver.a(mapimageio.o): In function `savePalettePNG': /home/dgambin/mapserver-6.0.1/mapimageio.c:274: undefined reference to `png_set_longjmp_fn' ./libmapserver.a(mapimageio.o): In function `saveAsPNG': /home/dgambin/mapserver-6.0.1/mapimageio.c:461: undefined reference to `png_set_longjmp_fn' ./libmapserver.a(mapimageio.o): In function `readPNG': /home/dgambin/mapserver-6.0.1/mapimageio.c:738: undefined reference to `png_set_longjmp_fn' collect2: ld returned 1 exit status Here is my configure: ./configure --with-ogr=/usr/local/bin/gdal-config --with-gdal=/usr/local/bin/gda l-config --with-wfs --with-wfsclient --with-wmsclient --enable-debug --with-curl -config=/usr/bin/curl-config --with-proj=/usr --with-jpeg --with-freetype=/usr/b in/ --with-postgis=/usr/bin/pg_config --with-mysql=/usr/bin/mysql_config --with- libiconv=/usr --with-kml=yes --with-php=/usr/include/php5 --with-png=/usr/local Since I have system libpng 1.2.27-2, I downloaded and installed 1.5.4 and put --with-png=/usr/local in my configure file. But seems like it doesn't help. I also tried with 1.4.8. Stiil the same issue. Also tried without --with-png=/usr/local (so it should use system libpng)...nothing I have compiled using newest gdal 1.8.1. GDAL compiled ok with libpng 1.5.4. Am I doing something wrong?

RE: [mapserver-users] how to define the CLASSITEM and EXPRESSION in this case?
Have you looked at this page in the documentation? http://mapserver.org/mapfile/expressions.html#arithmetic-operations-and-functions-that-return-a-number You should be able to do this. You wouldn't use a CLASSITEM, just an expression. Create individual classes for green, yellow, and red. The expression for green would be something like: EXPRESSION ([PopulationOver65] / [PopulationTotal] * 100 10) David. -Original Message- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of jjwang Sent: Thursday, September 08, 2011 12:47 AM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] how to define the CLASSITEM and EXPRESSION in this case?

So, it seems I have to somehow, somewhere enable 'ows_enable_request'. Looking
at the documentation, seems like if I had a map file, I could add the following
line to do so
ows_enable_request '*'
However, I am not using a map file at all. Not finding any documentation on
this setting, I tried the following to no avail
$map-{ows_enable_request} = '*';
Suggestions, anyone?

[mapserver-users] advice on best practice for MapServer layer in OL/Gmaps
In another tortured thread I am seeking advice on WMS with MapScript. My ultimate intent is to provide MapServer layers in OL/Gmaps/(some_other) web app. I need to use MapScript because of the flexibility and freedom it gives me in querying my datasources, and in constructing the map. Do I have to use WMS? What, if any, are the alternative? I notice that MapServer now has a `mode=tile` that is designed with Gmaps kinda app in mind. Is that a better mode? Would that work with OL as well? Or with Leaflet or some other client-side web mapping framework? Its been a while since I have used MapServer extensively for creating a full-fledged app, but the time to do is coming up now. I would really appreciate any advice on this front.

Re: [mapserver-users] MapScript WMS request
Hi Puneet,
A few things to try:
1- Reduce your map to a single layer if that's not already the case for
your first round of tests.
2- Try a GetCapabilities instead of GetMap, and make sure your layer
shows up properly and with no WARNING in the GetCapabilities XML output.
Make sure the name of the layer is not changed: if you have multiple
layers with the same name then the WMS handler will rename them to make
them unique (WMS spec requirement)
3- Enable DEBUG at the map and layer level and look for any hints as to
why nothing shows up. Compare the debug output between your WMS requests
and the regular MapServer requests (the one that you say works fine)
(see http://mapserver.org/optimization/debugging.html)
4- Frank's earlier suggestion to start by making things work from a
regular mapfile first and then converting/moving stuff to mapscript
progressively still stands as a great option.

that either you are going to be frustrated.
I would suggest getting your script working initially with an actual mapfile
and then if you really want to construct the map programmatically use
that as a guide.

wow! this is a super-awesome debugging technique. I have sent you the map
file off list to not pollute the entire list serve.
I was able to reproduce the issue with the copy of the mapfile you sent
off-list.
It turns out that mappostgis.c's msPostGISLayerGetExtent() is hardcoded to
always return
{minx = -2500, miny = -2500, maxx = 2500, maxy = 2500}
...and then it returns MS_SUCCESS.
I think this function should either be left unimplemented (this way MapServer
would fallback on other mechanisms), or return MS_FAILURE to indicate to the
calling code that it didn't do anything useful.
A quick search indicates an open ticket about the issue:
http://trac.osgeo.org/mapserver/ticket/3585
You could bump the ticket and hope someone works on it at the FOSS4G code
sprint next week.
The short term fix for you would be to set the ows_extent metadata in your
layer:
METADATA
ows_extent -180 -90 180 90
...
END
Thanks Daniel. I will bump the ticket. For now, see below --
Using the my.map file I sent you, with no further modifications to it, I am
able to successfully get an image back via
[http://localhost.local/cgi-bin/gmna?SERVICE=WMSVERSION=1.1.1REQUEST=GetMapBBOX=-180,-90,180,90SRS=EPSG:4326WIDTH=1200HEIGHT=600LAYERS=gmnaSTYLES=FORMAT=image/pngTRANSPARENT=true]
Note, no further modifications is required, that is, not even the ows_extent
-180 -90 180 90 bit in the layer METADATA. and I still get a good image.
However, if I use the following program to access the same map file, I get the
spurious minx = -2500, miny = -2500, maxx = 2500, maxy = 2500
in the GetCapabilities.
Finally, if I add the ows_extent -180 -90 180 90 line in the layer METADATA
in the my.map file, the GetCapabilities returns the correct bounds now,
however, the image is still blank.

I have now spent an enormous amount of time on this, and for now, I have to
move on. This is just not working out. Maybe I will try some other technique,
perhaps this mode=tile to see if I can get MapServer powered maps in my apps.
Thanks much for your help. If you (or anyone else) can come up with a bright
idea, I will be happy to try it.

[mapserver-users] mode=tile and MapScript
I am trying out mode=tile as detailed at
[http://mapserver.org/output/tile_mode.html], and actually, it works great!
Might be able to avoid the pains of WMS completely.
However, it works great with MapServer CGI. What if I want to use MapScript? In
other words, instead of
var urlTemplate = 'http://localhost/cgi-bin/myapp?';
urlTemplate += 'layers=layer1 layer2';
urlTemplate += 'mode=tile';
urlTemplate += 'tilemode=gmap';
urlTemplate += 'tile={X}+{Y}+{Z}';
I have
var urlTemplate = 'http://localhost/myapp.cgi?';
urlTemplate += 'tile={X}+{Y}+{Z}';
and I add mode=tile and tilemode=gmap on the server side. My question is --
one, will the above work? and, how do I pass mode=tile and tilemode=gmap and
the tile={X}+{Y}+{Z} parameters to the program? I didn't see any MapScript
documentation for these parameters. I need to translate a call such as
[http://localhost/cgi-bin/myapp?layers=layer1mode=tiletilemode=gmaptile=30+46+7]
into a MapScript request.
