Hello everyone. I have been working on this for about 10 hrs without any success -- and have tried lots of different stuff. Here is the scenario:

I put dbg.so-5.2.x file from the dbg-3.1.11-Linux-x86_64-ssl folder into the /usr/lib/modules/ dir -- and then I edited the /etc/php.ini file to include:

extension=dbg.so-5.2.x

[debugger]
debugger.enabled=on
debugger.profiler_enabled=on
debugger.hosts_allow=my.ip.here localhost
debugger.hosts_deny=ALL
debugger.ports=7869, 10000/16

And then I restarted Apache.. and my wizard shows the same old stuff:

# Your PHP.INI file is /etc/php.ini
# PHP extensions directory is /usr/lib/php/modules
# DBG (PHP DEBUGGER) is NOT INSTALLED

I've tried this a bunch of different ways -- I even remade PHP on the server. No luck. It's worth noting that I tried the non-64 bit builds and my Apache just stalled completely -- (it restarted OK.. but when I went to view any pages .. it just hung there.) Nothing came up in the error logs. I am pretty sure I am supposed be using the 64bit stuff since my box is a Core 2 Duo box.

Let's see.. what else did I try.. I tried moving the php.ini additions around the file (putting them at the bottom.. etc.) I also tried putting it all in a seperate .ini and putting that in /etc/php.d.

The top part of my phpinfo output is below -- any help here would be SOOOO AWESOME.

It's also worth mentioning that I tried making this a zend extension as well -- with no luck. I don't have any other zend extensions so i probably should have known that wouldn't work.

Thanks!

1. make sure that php and apache are 64bit. Just run ldd /path/to/httpd and check if it's linked against lib64 libraries or lib.
2. check apache error_log to see if anything related appears after you restart it.
