WampServer

This is on Windows XP 32-bit.

Everything runs fine until I enable the php_ldap extension. I then get the following error when it restarts:

"PHP Startup: Unable to load dynamic library 'F:/wamp/bin/php/5.3.8/ext/php_ldap.dll' - The specified module could not be found."

The path for the php_ldap.dll is correct in the error message and the file is in that folder. I used dependency walker, and when you load the php_ldap.dll it shows "Error opening file. The system cannot find the file specified (2)." for the following files:

LIBEAY32.DLL
LIBSASL.DLL
PHP5TS.DLL
SSLEAY32.DLL

All of the above dll's are in "F:/wamp/bin/php/php5.3.8" and all of the dll's except for LIBSASL.DLL are also in "F:\wamp\bin\apache\Apache2.2.21\bin"

in Dependancy walker you can add in the full path , so you can see where it is looking for the files.

Here is a couple screenshots from Dependency Walker:

One more thing, I installed the same version at home on Windows 7 64-bit and it works great. The problem is, I need to get this working on Windows XP at work.

did you try installing it on the c drive?

No, actually I didn't. I'll try that and see if it makes any difference. I will say that when I installed it on Windows 7, I used the D: drive, and it works fine.

I reinstalled WAMP on the C: drive of the XP box, and I get the exact same error, when enabling the LDAP PHP extension.

Problem also occur here same xp and same win7 64

According to the PHP Manual (http://www.php.net/manual/en/install.windows.extensions.php) "PHP <= 4.2.0 requires libsasl.dll (bundled), PHP >= 4.3.0 requires libeay32.dll, ssleay32.dll (bundled)".

I also found this concerning XAMPP where the fix was to move the LIBSASL.DLL out of the php directory to the apache bin directory before enabling the ldap extension (http://www.apachefriends.org/f/viewtopic.php?p=185776). I tried it and it worked.

This is also a problem for the AMPPS install that I tried so it would seem that including the LIBSASL.DLL in with PHP is the problem for all these distributions.

Thanks osu_sysmgr that worked like a charm!

Moving the dlls to the Apache bin folder solved it for me too. Thanks!

Hi,

One way to overcome the problems of dll not found or PHP extension that do not want to initialize is to automate the process of copying the dll in the apache/apache2.x.y/bin folder.
This can be done by editing the file wamp\scripts\config.inc.php and replace all the contents of

$phpDllToCopy = array(...
...

by

$phpDllToCopy = array (
	'fdftk.dll',
	'fribidi.dll',
	'icudt51.dll', //[modif oto] - Additions to avoid unknown error PHP 5.5.5
	'icuin51.dll',
	'icuio51.dll',
	'icule51.dll',
	'iculx51.dll',
	'icutest51.dll',
	'icutu51.dll',
	'icuuc51.dll',
	'icudt50.dll', //[modif oto] - Additions to avoid unknown error PHP 5.5
	'icuin50.dll',
	'icuio50.dll',
	'icule50.dll',
	'iculx50.dll',
	'icutest50.dll',
	'icutu50.dll',
	'icuuc50.dll',
	'icudt49.dll', //[modif oto] - Additions to avoid unknown error PHP 5.3/5.4
	'icuin49.dll',
	'icuio49.dll',
	'icule49.dll',
	'iculx49.dll',
	'icutest49.dll',
	'icutu49.dll',
	'icuuc49.dll',
	'libeay32.dll',
	'libmhash.dll',
	'libmysql.dll',
	'libsasl.dll', //[modif oto] - Additions to avoid unknown error
	'msql.dll',
	'libmysqli.dll',
	'ntwdblib.dll',
	'php5activescript.dll',
	'php5isapi.dll',
	'php5nsapi.dll',
	'ssleay32.dll',
	'yaz.dll',
	'libmcrypt.dll',
	'php5ts.dll',
	'php4ts.dll',
	);

It should then start and stop WampServer twice
