We are running into issues on our system where a Drupal module is calling 'include_once PEAR.php' and then civicrm is doing the same, triggering the above error 'Can redeclare class pear'.

The issue here is that at the time the drupal module includes pear, the php includes path is limited strictly to system paths, including the standard system version of pear. However, by the time civicrm attempts to include pear, the includes path has been modified to include civicrm's own bundled version of pear. Since these files appear new, the call to include_once() attempts to re-include pear.

So the issue here is a bit of a race condition: we need civicrm to modify the includes path before any other module has a chance to 'include_once PEAR.php'.

Assuming Drupal modules do their work within hooks and not globally, it might be enough to simply call 'civicrm_initialize()' within a 'hook_init()' in civicrm (this works for our particular use case). Is there are great cost calling civicrm_initialize() on every page load?

Or are there better ways to deal with this issue? Have other people had this come up before?

Hi,

A quick an dirty workaround is to delete the classes from the civicrm/packages folder and symlink them to the "main" pear location.

!/bin/sh
set -e

for i in Mail Mail.php PEAR.php ; do
    rm -rv packages/$i
    ln -sv /usr/share/php/$i packages/
done


Do you want to file an issue and an associated patch since u've done the work

thanx
