For those who haven't realised it yet, version 1.0 is in maintenance mode. This means that we are no longer working on it, apart from fixing the occasional bug. This also means that we are no longer supporting anyone else trying to compile or further develop 1.0 because it has reached it's end of life.
If you're keen to add features or otherwise help with the development of openlp.org, please work on version 2.0. We have a developer wiki with some articles on how to get started on Windows, Linux and Mac OS X, and other important pages like coding standards and a plugin developers' guide.
You're also welcome to join us in IRC, where we have developers, users, and friends of openlp.org hanging out and chatting from time to time.
