HOWTO: Compile php-gtk2 for Lucid Lynx

**martin_lindhe** · May 3rd, 2010

This is a mini-howto i collected from various outdated sources & a little testing.

The php-gtk2 package is currently not provided in the ubuntu repositories, it also depends on the pecl extension cairo.

When finished, you should have php-gtk2 running with php 5.3.

First the dependencies:

Code:

sudo apt-get install build-essential subversion php5-cli php5-dev libgtk2.0-dev libglade2-dev libcairo2-dev re2c

Then install pecl cairo from svn:

Code:

svn co http://svn.php.net/repository/pecl/cairo/trunk pecl-cairo
cd pecl-cairo
phpize
./configure
make
sudo make install

Next, install php-gtk2 from svn:

Code:

svn co http://svn.php.net/repository/gtk/php-gtk/trunk php-gtk
cd php-gtk
./buildconf
./configure
make
sudo make install

Assuming all went well, configure the extensions to load with php5-cli.

IMPORTANT: in Ubuntu Lucid, /etc/php5/cli/conf.d/ and /etc/php5/apache2/conf.d/ is symlinks to /etc/php5/conf.d/
This means that if you install php_gtk2 in this directory, it will also load when php is ran from Apache,
causing server to crash. php_gtk2 is only meant to be run from the cli.

So first remove the symlink, make a ordinary cli/conf.d/ directory and copy the .ini files there:

Code:

sudo rm /etc/php5/cli/conf.d
sudo mkdir /etc/php5/cli/conf.d
sudo cp /etc/php5/conf.d/*.ini /etc/php5/cli/conf.d/

Then install php_gt2k + cairo extensions:

Code:

echo "extension=/usr/lib/php5/20090626/php_gtk2.so" | sudo tee /etc/php5/cli/conf.d/php_gtk2.ini
echo "extension=/usr/lib/php5/20090626/cairo.so" | sudo tee /etc/php5/cli/conf.d/cairo.ini

Finally, verify they load correctly

Code:

php -m | grep php-gtk

Good luck!

EDIT: fixes as suggested by Compyx

Nice one! I finally got php-gtk working thanks to this howto.

A few comments:

You have a typo in your command to install the dependencies, it should read:

Code:

sudo apt-get install build-essential subversion php5-cli php5-dev libgtk2.0-dev libglade2-dev libcairo2-dev re2c

you had an 'l' too many in 'llibglade2-dev' and an 'l' too few in 'ibcairo2-dev'.

Echoing with sudo and IO-redirection doesn't work:

Code:

sudo echo "extension=/usr/lib/php5/20090626/php_gtk2.so" > /etc/php5/conf.d/php_gtk2.ini
bash: /etc/php5/conf.d/php_gtk2.ini: Permission denied

This can be fixed by running the command in a new shell:

Code:

sudo bash -c 'echo "extension=/usr/lib/php5/20090626/php_gtk2.so" > /etc/php5/conf.d/php_gtk2.ini'

With these fixes php-gtk installed fine.

Or even better, using tee, that's what it's for:

Code:

echo "extension=/usr/lib/php5/20090626/php_gtk2.so" | sudo tee /etc/php5/conf.d/php_gtk2.ini

even better, thanks!

I've installed Ubuntu 10.04 (Lucid Lynx) Desktop and followed this howto. But when I test my PHP GTK installation by typing "sudo make test" after "sudo make", every test will fail.

During the installation I can't see anything going wrong...

Any ideas?

I installed both packages to /opt.

On my machine all the tests fail as well, however, the installation goes fine and PHP GTK actually works. So, I assume, something is wrong with the test suite itself.

All tests failed with my install too, but php-gtk worked. Unfortunately I had to disable the extensions because none of my local websites would display anything with them enabled. In /var/log/apache2/error.log I noticed messages like these:

Code:

(page=mail&action=test:1238): GLib-GObject-CRITICAL **: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
(index.php:1239): GLib-GObject-CRITICAL **: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed

I'm guessing not everything is working as it should. When compiling php-gtk I noticed some nasty compiler warnings about integers and pointers having different sizes and functions expecting pointers but getting integers, so perhaps php-gtk isn't 64-bit ready or not including the proper headers. I'll try to look into those issues when I can find the time.

Hello, I updated the first post with explanation & instructions how to install php_gtk2 for php5-cli only.
Your problem is the symlink that ubuntu has installed between apache's php extensions and php-cli extensions, so apache loads the php_gtk2 extension and crashes.
php5_gtk2 can of course not run from the webserver

After removing the symlink and creating a cli/conf.d directory everything works as expected. Thanks!
