Getting ZendDebugger to work on Centos5.1October 21, 2008
Well I had to setup a Zend Studio for Eclipse on Centos today, me thinking that it would be a blissful journey, abruptly followed by the realization that Centos wasn’t going to play nice. First thing after a clean install I ran yum update to make sure the system was up to date.
I tried to install ZendFramework 1.7, ZendStudio6.1 & PHPUnit3 and installed as I have before but came against a brick wall, PHPUnit would not install, due to PHP-XML being missing.
yum install php-xml
Which installs php-xml5.1.6, okay, I know I need 5.2 at least but for now I want to make sure PHPUnit will install.
pear channel-discover pear.phpunit.de
pear install phpunit/PHPUnit
Once PHPUnit was installed I ran the test cases, ZS complains with the follow:
Error launching 'AllTests.php
The session counld not be startd.
In order to generate debug inormation, please make sure that the debugger is properly configured as a php.ini directive
I run phpunit from shell to get:
Failed loading /usr/lib/php/modules/ZendDebugger.so: /usr/lib/php/modules/ZendDebugger.so: undefined symbol: zend_memory_usage
Okay so ZendDebugger isn’t working, php -v shows me:
PHP 5.1.6 (cli) (built: Sep 20 2007 10:16:10)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
So I need a new version of PHP, PHP5.2.6 will do, yum update php tells me that 5.1.6 is that latest version, so I need to find a repository that has one.
Edit the line below.
your file should now look like this:
# !!!! CAUTION !!!!
# This repository is a proving grounds for packages on their way to CentOSPlus and CentOS Extras.
# They may or may not replace core CentOS packages, and are not guaranteed to function properly.
# These packages build and install, but are waiting for feedback from testers as to
# functionality and stability. Packages in this repository will come and go during the
# development period, so it should not be left enabled or used on production systems without due
Now run the following
yum install php
You should get something simular to this….
Package Arch Version Repository Size
php i386 5.2.6-2.el5s2 c5-testing 1.2 M
php-cli i386 5.2.6-2.el5s2 c5-testing 2.4 M
php-common i386 5.2.6-2.el5s2 c5-testing 230 k
Updating for dependencies:
php-ldap i386 5.2.6-2.el5s2 c5-testing 31 k
php-xml i386 5.2.6-2.el5s2 c5-testing 97 k
Now I ran the test and got the following error.
Failed loading /usr/lib/php/modules/ZendDebugger.so: /usr/lib/php/modules/ZendDebugger.so: cannot restore segment prot after reloc: Permission denied
Okay, that was totally unexpected, so after a little searching with my best friend (google) I found the following command
Ran the tests again….
PHPUnit 3.3.2 by Sebastian Bergmann.
Time: 0 seconds
OK (7 tests, 0 assertions)
One thing to make note of; when I restarted the box, SELinux had been reactivated so I disabled SELinux by doing the following (this is not ideal, i’ll have to look allowing doing this a better way).
Doing this disabled SELinux so that we I wouldn’t get the permissions error. Alternatively I could of placed the setenforce command in a startup script (bashrc or something simular).
