<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.</DIV>
<P class=MsoNormal> </DIV>
<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:</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal> http://10.0.0.59/testmap/tile.php?map=testmap&g=all&i=gif&t=-11200&l--29000&s-1000000</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>The browser is finding tile.php without problems, but Apache is returning "HTTP 500 Internal Server Error".</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>Looking in the apache logs, I see:</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>[Wed Jun 09 14:02:42 2010] [error] [client 127.0.0.1] </DIV>
<P class=MsoNormal>PHP Notice: Undefined offset: 6 in /var/www/testmap/htdocs/tile.php on line 229</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>[Wed Jun 09 14:02:42 2010] [error] [client 127.0.0.1] </DIV>
<P class=MsoNormal>PHP Warning: Division by zero in /var/www/ testmap /htdocs/tile.php on line 229</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>So I look at my tile.php. Lines 228 and 229 are:</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal> $inchesPerUnit = array(1, 12, 63360.0, 39.3701, 39370.1, 4374754);</DIV>
<P class=MsoNormal> $geoWidth = $scale/($oMap->resolution*$inchesPerUnit[$oMap->units]);</DIV>
<P class=MsoNormal> </DIV>
<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.</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>The mapfile contains "UNITS DD"</DIV>
<P class=MsoNormal> </DIV>
<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.</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>OTOH, a glance at the mapserver 5.6.3 source reveals:</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal> enum MS_UNITS {MS_INCHES, MS_FEET, MS_MILES, MS_METERS, MS_KILOMETERS, MS_NAUTICALMILES, </DIV>
<P class=MsoNormal> MS_DD, MS_PIXELS, MS_PERCENTAGES};</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>Which gives MS_DD the value of 6.</DIV>
<P class=MsoNormal> </DIV>
<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?</DIV>
<P class=MsoNormal> </DIV>
<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).</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>Is there a more recent version of KaMap, than the one I downloaded from maptools.org?</DIV>
<P class=MsoNormal> </DIV>
<P class=MsoNormal>Is there any version of KaMap that has kept up-to-date with current developments in mapserv?</DIV>
