Here is the first question from the Dependency Walker FAQ Page:

Q (or "F" <g>): Dependency Walker seems to only show some of my      <- lol
application's dependencies. Why doesn't it show all of them? 

A: When you first open a module in Dependency Walker, it only shows
implicit, forwarded, and delay-load dependencies. Many dependencies are
loaded dynamically and will not be detected until you profile the
application from within Dependency Walker. For more information, see the
"Types of Dependencies Handled By Dependency Walker" and "Using
Application Profiling to Detect Dynamic Dependencies" sections in help. 

It is difficult to detect dependencies on run-time loaded
("LoadLibrary") calls, since they're not statically referenced in the
executable.

Hi Ed,
if the mapscript.dll would load another dll that is noch installed,
"dependency walker" ( www.dependencywalker.com ) show me the missing
dll's.
i don't found the ZLIB.dll on the machine but i found it on our HAHTSite
MapXtreme Server.
But if i need this dll, why couldn't i download it from
http://www2.dmsolutions.ca/mapserver/dl/ ?
Well, tomorrow i will test it and report the result here ( for other
developer with the same problem ) i also test another php version if the
zlib.dll don't solve the problem

Thank you very much for your help.

Have a nice evening! :-)

You may be unable to load a DLL because *that DLL* loads another DLL at
runtime.  I think the most commonly overlooked DLL in MapServer
installations is ZLIB.DLL - do you have it installed in the system path?

Thanks for the fast help, but i have still the same problem

i have load the mapscript_4.0.1.dll with "dependency walker" ( btw :
very good tool ) MPR.dll -> Warning: At least one module has an
unresolved import due to a missing export function in a delay-load
dependent module.

But i think it's not the problem.
If i try to load the php_GD2.dll with "dependency walker" the same
warning is displayed and the dl(php_GD2.dll) works fine.

My php.ini Settings
extension_dir = "c:\php\extensions\"
enable_dl = On
;extension=php_mapscript_4.0.1.dll <- only a comment

<HTML>
<BODY>
<?php 
      dl("php_mapscript_4.0.1.dll");
//     dl ("php_gd2.dll");
      phpinfo();
 ?>
</BODY>
</HTML>

result :
Unable to load dynamic library
'C:/php/extensions/php_mapscript_4.0.1.dll' 

the php_mapscript_4.0.1.dll and the php_GD2.dll are in the same
directory how can php found the php_GD2.dll and not the
php_mapscript_4.0.1.dll when the both are in the same directory ?
i guess its a version conflict with php
Use anyone MapServer/MapScript with a WA(M)P configuration an can tell
me which version of Apache/Php/Mapscript he use.

according to the homepage mapscript 4.0 is compatible with PHP 4.1.2 and
up (PHP 4.3.2 or more recent recommended) source :
http://mapserver.gis.umn.edu/doc/phpmapscript-install-howto.html#example

try setting extension_dir="c:\php\extensions"

if you set extension=php_mapscript_4.0.1.dll you may not need to set
enable_dl=On.  enable_dl is enabling dynamic loading.  If you leave the
extension out of php.ini and enable_dl=On then you can use dl(
'php_mapscript_4.0.1.dll' ); in your scripts to load mapscript.  If you
add extension=php_mapscript_4.0.1.dll then you do not need to use dl in
your script and in fact it will cause an error.

the next thing to try is to get the dependency walker from
www.dependencywalker.com and run it on php_mapscript_4.0.1.dll, it will
tell you if all the dll dependencies can be found.  Windows will
sometimes give you misleading error messages, like the extension can't
be found ... often this means that a dll the extension relies on can't
be found.

Cheers,

Paul
