The problem
I’ve tryied to execute a php script containing a dl() call to a .so from the command line and I’ve got the message:

Warning: dl(): Dynamically loaded extensions aren't enabled in /home/roberto/tmp/helloworld.php on line 6

The cause

The web host has not enabled dynamically loaded extensions.

The solution
I asked to the php interpreter where to find the configuration:

php --ini

Configuration File (php.ini) Path: /etc/php5/cli
Loaded Configuration File:         /etc/php5/cli/php.ini
Scan for additional .ini files in: /etc/php5/cli/conf.d
...

So with a simple sudo vi /etc/php5/cli/php.ini I changed the parameter enable_dl=Off to enable_dl=On.

Enjoy,

This post is really enlightning of how open source can really change/improve your life.

To keep your wxwidgets up-to-date on your ubuntu, simply add

deb http://apt.wxwidgets.org/ gutsy-wx main

to your /etc/apt/sources.list file. Then run

sudo apt-get update

to get the wx package list. Then type:

sudo apt-get install libwxgtk2.8-0 libwxgtk2.8-dev wx2.8-headers wx-common

or open synaptic to update your wx libraries.

Note that also the python bindings will be available for upgrade

where in the upper section i write my code and sending the output stream on the bottom section.

I’ve tried to use gecko.WebControl on Mono under Ubuntu Linux and I kept on getting:

That’s why even if the /usr/lib/firefox/libgtkembedmoz.so library is there is not visible to the LD_PATH.
