Fails to load xdebug - why?

I'm trying to install the debugger extension Xdebug [xdebug.org] for PHP on Apache running on my local Mac. I tried the built-in PHP installation and also the Entropy PHP package [entropy.ch]. I got the extension from the Xebug site and also a precompiled version from Komodo [code.activestate.com]. It's a PPC Mac and the extension is said to be universal binary, i.e. works on PPC Macs.

Xdebug never shows up in the phpinfo(); output, even though it loads the correct php.ini file (double-checked in output) and the .ini file specifies the extension correctly.

No matter what PHP/Xdebug combo, when I restart Apache, I see something like this in my error log:

[Fri Mar 04 12:26:49 2011] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]
Failed loading /usr/local/php5/lib/php/extensions/no-debug-non-zts-20060613/xdebug.so: (null)
[Fri Mar 04 12:26:50 2011] [notice] Digest: generating secret for digest authentication ...
[Fri Mar 04 12:26:50 2011] [notice] Digest: done

Is there any way to get more info about why it failed loading? The error message just says (null) - not very helpful. Any other ideas?

Any ideas?

I think this may be an Apache issue because I tried two different PHP builds and two different Xdebug builds, all fail the same way and the only constant is the Mac OS built-in Apache.

With this level of specificity, you might want to ask in our PHP forum, or in an Xdebug-specific forum.

We're strongest here on questions about the Apache server itself, and it's quite possible that no one reading here has ever tried Xdebug (i.e. you're the first).

Ok, I understand.

Is there a way to elicit more verbose error messages though? It would help if Apache told me why it failed loading instead of just "null".

It looks like you've already got your ErrorLevel set very low. So if Apache isn't logging any more-specific errors, it's likely because it isn't being passed any additional info to log...
