Thank you for reporting this to Ubuntu. We can't properly support binary extensions with rapid release, this is why the pkg-config file was removed. Please try the mozilla-plugin.pc file as it should provide the ability to build NPAPI plugins whose interface most likely won't be changing over time.

This allowed binary extensions to be configured and built in a sane way. In the Precise version of firefox-dev, this file has been removed due to the "Removing XULRunner from oneiric" effort [1]. Unfortunately, this effectively breaks proper build configuration for third-party binary extensions, such as mozilla-gnome-keyring [2] and forces the Ubuntu package [3] to use hardcoded paths. I don't see any point in "hiding" the XULRunner interface in Ubuntu, since this is what locks Ubuntu out for interesting binary firefox extensions. Other distributions such as Fedora and Debian still ship the libxul.pc file. Please include the libxul.pc file in the firefox-dev package. --- [1] https://lists.ubuntu.com/archives/ubuntu-motu/2011-May/007088.html [2] https://github.com/infinity0/mozilla-gnome-keyring [3] https://launchpad.net/~fat-lobyte9/+archive/ppa-public/+packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1030504/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
