Is there some magic in building php for arm?

[Yan Seiner <yan@xxxxxxxxxx>]

I hope someone can shed some light on this.   I have an embedded system 
that uses an arm processor architecture.

I've been trying to build php4 with shared extensions enabled, but I am 
failing miserably. I was able to build ming as a part of php by linking 
to libming, but now I am trying to build xcache 
<http://trac.lighttpd.net/xcache/>, and failing.

I can build php4 and xcache, but the problem comes in when I try to run 
php with xcache:

root:~> php -v
PHP 4.4.2 (cgi-fcgi) (built: Nov 14 2006 14:29:34)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies

no xcache in sight.

If I set up /etc/php.ini to use zend_extension = xcache.so and try to 
explicitly force it to read /etc/php.ini, then it fails with

root:~> php -v -c /etc
Extensions are not supported on this platform.

and if I try to use regular extensions extension = xcache.so then I get

PHP Warning: Unknown(): Cannot dynamically load xcache.so - dynamic
modules are not supported in Unknown on line 0

so.... It seems that my build is broken.  First of all, it doesn't seem 
to use /etc/php.ini by default, and second, it can't load dynamic 
modules.  Has anyone gotten dynamic modules to work in PHP built for 
arm? What am I doing wrong????

Debian shows both php4 and xcache, so I am guessing that it is possible....

Google is mute....  Or at least I have not found anyone with this error.
