Installing XDebug on Ubuntu 12.04

mkdir ~/opt && cd ~/opt
tar -xzvf xdebug-2.2.2.tgz && cd xdebug-2.2.2/
auto-apt run ./configure
sudo checkinstall
sudo nano /etc/php5/mods-available/xdebug.ini
sudo php5enmod xdebug
php -i | grep xdebug


  1. Create directory opt inside the home directory and change to created directory. Change directory name and location as needed
  2. Get the latest version of Xdebug. Adjust URL to point to the latest or desired Xdebug version
  3. Prepare the build environment for a PHP extension. See phpize manual.
  4. Use auto-apt just in case there are missing dependencies. Not likely to happen in this case.
  5. Build extension
  6. Create and install deb package. For details see Checkinstall wiki.
    1. The package documentation directory ./doc-pak does not exist.
      1. Should I create a default set of package docs?  [y]: 
      2. Type y
    2. Please write a description for the package.
      1. End your description with an empty line or EOF.
      2. Enter Xdebug 2.2.2 or whatever might be suitable
    3. This package will be built according to these values:
      1. Options 0 to 13 listed
      2. Enter a number to change any of them or press ENTER to continue:
      3. Make changes as needed
  7. Create extension configuration file. For details see Xdebug Documentation.
  8. Enable extension

NetBeans IDE 7.3 Beta 2 - Find Usages

NetBeans 7.3 Beta 2 has been released earlier today. You will find more information here: NB 7.3 beta 2 Release Information

One of the most usable improvements I found is the way how results are displayed/ordered in Find Usages Logical View.

In earlier versions it was quite hard to find what are you looking for. Attempting to get usages of a method having common name such as init(), setHandler() or run() might return hundreds of results. The only way to figure out a location of a file where usage occurred was to place a mouse over a file name and wait for a tooltip to display.

Find Usages - Logical View is way better organized in NetBeans IDE 7.3 Beta 2.

One can easily disregard usages of run() method in EZComponents or Zend Framework and focus on desired components.

Hopefully this change will find it's way to Refactoring - Logical View in final NetBeans IDE 7.3 release.
