These are instructions for installing Xdebug from a Git checkout. Please refer
to https://xdebug.org/support.php for support.
Introduction
------------
You need to compile Xdebug separately from the rest of PHP. You need to have
access to the scripts ``phpize`` and ``php-config``. If your system does not
have ``phpize`` and ``php-config``, you will need to compile and install PHP
from a source tarball first, or install a ``php-dev`` package if your
distribution provides one. These scripts are by-products of the PHP
compilation and installation processes and are needed to compile external
extensions. It is important that the source version matches the installed
version as there are slight, but important, differences between PHP versions.
Clone
-----
You can clone the Xdebug source directory with::
git clone https://github.com/xdebug/xdebug.git
Then move into this new directory::
cd xdebug
Although it is recommended to run the latest version from the **master**
branch, older versions are available through tags. For example to checkout the
2.5.5 release, you can switch to it with ``git checkout XDEBUG_2_5_5``.
Compile
-------
If PHP is installed in a normal, and uncomplicated way, with default locations
and configuration, all you will need to do is to run the following script::
./rebuild.sh
This will run ``phpize``, ``./configure``, ``make clean``, ``make`` and ``make
install``.
The long winded way of installation is:
#. Run phpize: ``phpize``
(or ``/path/to/phpize`` if phpize is not in your path).
#. ``./configure --enable-xdebug`` (or: ``../configure --enable-xdebug
--with-php-config=/path/to/php-config`` if ``php-config`` is not in your
path)
#. Run: ``make clean``
#. Run: ``make``
#. Run: ``make install``
#. Add the following line to ``php.ini`` (which you can find by running ``php
--ini``, or look at ``phpinfo()`` output): ``zend_extension="xdebug.so"``.
Please note, that sometimes the ``php.ini`` file is different for the
command line and for your web server. Make sure you pick the right one.
#. Unless you exclusively use the command line with PHP, restart your webserver.
#. Write a PHP page that calls ``phpinfo();``. Load it in a browser and
look for the info on the Xdebug module. If you see it, you have been
successful! Alternatively, you can run ``php -v`` on the command line to
see that Xdebug is loaded::
$ php -v
