If you're missing installation instructions in the readme and normal installations don't work, this is what worked for me on Centos 5.9 with php 5.3.3

cd /tmp
git clone
cd runkit
pecl install package.xml

// Add to php.ini:

// Restart your webserver
service httpd restart

The project is now hosted on

To install a release version, simply type

sudo pecl install

See the for the full list of release files.

To get most fresh and hot features you may also build the extension from master-branch source code. Clone it with
git clone git://
and follow the instructions in the README file.

To install the latest release via PECL you should access Runkit's PEAR channel:

pear channel-discover

Then to install Runkit just type:

pecl install zenovich/runkit

If the normal PECL installation doesn't work for you, you may want to install from SVN instead:

svn checkout
cd trunk
pecl install package.xml

After pecl has finished installing runkit, add the following line to your php.ini file(s):

Then restart your webserver, and runkit should now be installed and working with your PHP installation.
