Environment:

Linux Kernel 2.2.9
Apache 1.3.12
MySQL 3.22.31
IMAP 2000.RELEASE-CANDIDATE.7
openLDAP 2.0.4
PHP 4.0RC2

Error:

When trying to start Apache with the PHP4 Module --
/usr/local/libexec/libphp4.so: undefined symbol: ldap_get_lderrno


I have compiled Apache with loadable modules. IMAP is working properly, as is MySQL. Everything works if I do not compile in LDAP support. The LDAP server is functioning properly.

I have seen articles stating that I must configure, build, and install openLDAP first, then configure, build, and install PHP4. I have done that, but I keep getting this error.

Here are all of the libraries linked in the module:
