Hello,
I'm attempting to get chameleon running on OS X, and I am having a
problem. I hope that somebody will be able to offer some helpful
suggestions on how to resolve this problem.
The problem is:
When I attempt to load
http://localhost/chameleon/cwc2/cwc2.php?
service=VCG&request=GetApplication&version=0.1.0
I get the following results:
Warning: dl(): Unable to load dynamic library
'/usr/lib/php/extensions/no-debug-non-zts-20020429/php_dbase.dylib' -
(null) in /usr/local/lib/chameleon/htdocs/common/mlt/mlt.php on line
251

I am running:
MapServer version 4.4.1
Apache/1.3.33 (Darwin)
Chameleon version 2.2
I added the following to my httpd.conf file:
