Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.I'm getting the following error when trying to enable the Boomerang module without first enabling the library module:
Fatal error: Call to undefined function libraries_get_libraries() in /home/quickstart/websites/d6sandbox.dev/sites/all/modules/contrib/boomerang-HEAD/boomerang.install on line 17
...though the libraries module is defined as a dependency. I was expecting Drush to tell me "The following projects will be enabled: libraries". If I try enabling Boomerang from the modules page, I'm told "You must enable the Libraries module to install Boomerang."
In case it might help, here's the call stack:

Comment #1
jonhattanThis is because we check requirements for all modules and then enable any of them. So at the time we check requirements for boomerang, libraries is not enabled.
Comment #2
jonhattanwoah same result in drupal:
It can be fixed in drush with a refactoring of pm-enable but we will stay in sync with drupal. Moving to boomerang issue queue.
to replicate: uninstall libraries and try installing boomerang and libraries at the same time.

matt v. commentedjonhattan,
Thanks for looking into that. For what it's worth, I was testing on Pressflow, which was giving me the "You must enable the Libraries module to install Boomerang" message if I tried enabling Boomerang by itself. It worked fine if I enabled it at the same time as the Libraries module. After seeing your response in #2, I tested in Drupal and got the same error you did. Pressflow apparently handles things a bit differently, in this case.
I'm the developer of the Boomerang module, so I guess I'll have to look into a fix for this myself. The hook_requirements implementation I used is based on code in 3 Tips For Using External Libraries With Drupal. It would be relatively easy to miss the issue though, if you already had the Libraries module installed.
Comment #5
hanoiiJust a small requirement addition for the libraries module to be enabled. This will prevent the fatal error.
Comment #6
matt v. commented@hanoii Thanks! I've applied the patch.
