<div class=Section1>
<p class=MsoNormal>We've been running a few map servers on Windows, using KaMap
to deliver tiles, for a couple of years. I'm trying to move one of them
onto a new Ubuntu box, and I'm having problems.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My problem is when I try to access a tile from a browser,
passing args directly to tile.php in the URL:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> http://10.0.0.59/testmap/tile.php?map=testmap&g=all&i=gif&t=-11200&l--29000&s-1000000<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The browser is finding tile.php without problems, but Apache
is returning "HTTP 500 Internal Server Error".<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Looking in the apache logs, I see:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>[Wed Jun 09 14:02:42 2010] [error] [client 127.0.0.1] <o:p></o:p></p>
<p class=MsoNormal>PHP Notice: Undefined offset: 6 in /var/www/testmap/htdocs/tile.php
on line 229<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>[Wed Jun 09 14:02:42 2010] [error] [client 127.0.0.1] <o:p></o:p></p>
<p class=MsoNormal>PHP Warning: Division by zero in /var/www/ testmap /htdocs/tile.php
on line 229<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So I look at my tile.php. Lines 228 and 229 are:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> $inchesPerUnit =
array(1, 12, 63360.0, 39.3701, 39370.1, 4374754);<o:p></o:p></p>
<p class=MsoNormal> $geoWidth =
$scale/($oMap->resolution*$inchesPerUnit[$oMap->units]);<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>It looks like "$oMap->units" has the value "6",
which is not a valid index into $inchesPerUnit, so we get the errors, above.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The mapfile contains "UNITS DD"<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My first thought was that since I'd installed a more recent
version of mapserver on the unix box than had been running on the windows box,
maybe php_mapscript.so's ms_newMapObj() function is returning a different set
of values in units. But I downloaded the most recent version of tile.php,
and in it the $inchesPerUnit array has the same values.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>OTOH, a glance at the mapserver 5.6.3 source reveals:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> enum MS_UNITS {MS_INCHES, MS_FEET, MS_MILES,
MS_METERS, MS_KILOMETERS, MS_NAUTICALMILES, <o:p></o:p></p>
<p class=MsoNormal> MS_DD, MS_PIXELS,
MS_PERCENTAGES};<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Which gives MS_DD the value of 6.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So, am I correct in my understanding that the version of
tile.php I am using will not work with mapserver 5.6 without modifications?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I downloaded kamap from http://ka-map.maptools.org/index.phtml?page=downloads.html.
The tile.php in it is v 1.41. (The one I was using on the Windows box was
v 1.1).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there a more recent version of KaMap, than the one I
downloaded from maptools.org?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there any version of KaMap that has kept up-to-date with
current developments in mapserv?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
