centos 6.4: apache not loading xdebug. Says undefined symbol: sapi_globals

| | August 4, 2015

I am using centos 6.4

[root@storm]# cat /etc/centos-release
CentOS release 6.4 (Final)

I have installed xdebug using the command (only showing the partial output)

[root@storm]# pecl install Xdebug
Failed loading xdebug.so:  xdebug.so: cannot open shared object file: No such file or directory

configuration option "php_ini" is not set to php.ini location
You should add "zend_extension=/usr/lib64/php/modules/xdebug.so" to php.ini

The following is my /etc/php.ini

[xdebug]

xdebug.remote_enable=on
xdebug.remote_handler=dbgp

xdebug.remote_port=9000

after i do

[root@storm]# service httpd restart

I see the following lines added in the /var/log/httpd/error.log

[Fri Jul 24 13:21:12 2015] [notice] caught SIGTERM, shutting down

which shows xdebug in not loaded.

The following is the php details

I have test.php with

<?php

phpinfo();
?>

when i open http://localhost/test.php in browser the following is the output. (it does not show xdebug as loaded because of which i got the doubt and saw the output of /var/log/httpd/error.log)

2 Responses to “centos 6.4: apache not loading xdebug. Says undefined symbol: sapi_globals”

  1. You try

    zend_extension="/usr/lib64/php/modules/xdebug.so"
    [xdebug]
    xdebug.remote_autostart=on
    xdebug.remote_handler=dbgp
    ...
    

    If there are problems, then try to rewrite the compiler installation

  2. It looks like your xdebug.so library is linked incorrectly. Try to link the shared library manually or download a version that matches your OS (including your kernel version) and your version of apache. Also this is a known bug in some versions of apache/php (https://bugs.php.net/bug.php?id=17147): try to update your version of apache.
