What is Licq?

Licq is a multi-threaded ICQ (originally; now it supports AOL and MSN as well) clone written mostly in C++. It uses an extensive plugin system to manage many different functions. The main GUI is written using the Qt widget set. Licq is distributed under the GNU General Public License (GPL).

Development is very ongoing, with new features and bugs fixed frequently, so updates are available often. The current version should be very stable, but as with all software use it at your own risk.

Browse the list of features, take a look at the screenshots and then download Licq and try it out. If you need help, check out the frequently asked questions, our section with tips and the support page.

Check out the installation guide for how to install the latest version of Licq.

ICQ Login problems

It seems the ICQ servers has started to reject old clients. Several clients (included Licq) were blocked from logging on.

Latest SVN version (as of r6387) of Licq contains an update to allow Licq to log on again.

For users of Licq 1.3.4 or 1.3.5, the following patches should get you back online:
Login patch for Licq 1.3.4
Login patch for Licq 1.3.5

Patch instructions

1) Download and unpack Licq source
2) Go to licq directory and run "patch -p0 < licq-1.3.5-logonfix.patch"
3) Build as normal (./configure and make)
4) Install. (If you already had the same Licq version installed, just copying src/licq to /usr/bin or /usr/local/bin should be enough.)

Translators Needed

Qt4-Gui has come a long way since it was branched of from the old Qt-Gui and is now stable enough to be included in the next release of Licq. However, all the changes, improvements and fixes also means that the translations have been affected and most of them are currently very out of date. Some of them needs to be updated for Qt-Gui as well.

Unless we get them up to date again, some of the translations will probably be dropped. But we would of course much rather see them updated and maintained. So if you would like to see Licq in your native language, your contribution would be very welcome.

For more information see this thread or join us in the Licq IRC channel.

Qt4-GUI moved to trunk

Qt4-GUI plugin is planed to be included in the next release and has thus been moved in svn. The new location is trunk/qt4-gui (was branches/qt-gui_qt4). See this mail for information on how to update your working copy.
