Mapscript - problem with binary grid (ADF)

[Marcin Zajączkowski]

Hi,

can anyone please help me, i encountered two problems using mapscript
and am unable to figure out the source of the problems.
I have stopped using mapserver executable /cgi-bin/mapserv and started
using mapscript.

1) When using /cgi-bin/mapserv i am able to view grid maps saved in .adf
format, when i started using mapscript they are not drawn.

2) When i try executing a query using mapscript everytime i get no
results (no objects found). When executing the same query on both
/cgi-bin/mapserv and mapscript, /cgi-bin/mapserv find the proper results
and mapscript gets no results.

In both describled cases i use the same maps.

Below are the script used for generating proper images and
/cgi-bin/mapserv and mapscript compile options (in both cases i
downloaded them from the web not compiled them myself)

vars.php
<?php
$VARS["map"] = $_GET[map];

if (PHP_OS == "WINNT" || PHP_OS == "WIN32")
         @dl("php3_mapscript.dll");
else
         dl("php_mapscript.so");

// Odczyt mapy
if( ! $g_Map )
{
         $g_Map = ms_newMapObj( $VARS["map"] );

         $g_Map->web->set("log", "c:/temp/log.log");
         $g_Map->set("debug", 1);
}
?>

viewMap.php
<?php
include('vars.php');

function MS_MAP2IMAGE_X($x,$minx,$cx){ return (MS_NINT(($x - $minx)/$cx));
}
