The Xdebug extension is not loaded. No code coverage will be generated on Ubuntu with Xampp

Question

I have a problem to install xdebug on my Ubuntu Server which is using xampp. I know in Stack Overflow there are several questions about this kind of problem but I did not find any solution.

First this is the output of php --version command:

PHP 5.3.8 (cli) (built: Sep 19 2011 13:29:27)

Output of php --ini command:

Scan for additional .ini files in: (none)

Output of php -m command:

xdebug  

When I paste the output of phpinfo() in http://xdebug.org/wizard.php, the site shows the following:

Tailored Installation Instructions

Summary

Xdebug installed: 2.2.0

Server API: Command Line Interface

Windows: no

Zend Server: no

PHP Version: 5.3.8

Zend API nr: 220090626

PHP API nr: 20090626

Debug Build: no

Thread Safe Build: no

Configuration File Path: /opt/lampp/etc

Configuration File: /opt/lampp/etc/php.ini

Extensions directory: /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626

You're already running the latest Xdebug version

But here are the instructions anyway:

... ... ... (lines truncated) ... ... ...

I write this on my /opt/lampp/etc/php.ini at the bottom:

[xdebug]  
zend_extension = /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so  
xdebug.profiler_output_dir = "/tmp/xdebug"  
xdebug.profiler_enable = On  
xdebug.remote_enable = On  
xdebug.remote_host = "localhost"  
xdebug.remote_port = 10000  
xdebug.remote_handler = "dbgp"  

Output of phpunit --version is as follows:

 PHPUnit 3.6.11 by Sebastian Bergmann.  

Now my actual problem arises:

When I use the following command it shows that xdebug is not installed:

phpunit --coverage-html ~/build/logs/coverage  

This command's output is as follows:

The Xdebug extension is not loaded. No code coverage will be generated.  

Answer 1

Not sure if it helps but...

I had the same error when going through the phpunit tutorial - getting the error at chapter 7. http://phpunit.de/manual/current/en/organizing-tests.html

Took me a while to realise xdebug was set up in /etc/php5/apache2/php.ini but not in /etc/php5/cli/php.ini.

Worked okay for me after copying the xdebug settings from apache2 to cli.

Answer 2

See your "php.ini" in the folder "cli" on php5, this not have the lines references for your xdebug. So, add the lines for xdebug.

Answer 3

It is possible that phpunit uses a different PHP version from the one that you have installed Xdebug for. Try to use php `which phpunit` --coverage-html ~/build/logs/coverage, if that works, then phpunit uses the wrong PHP by default. This could be a path issue.
