This guide is based (but not only) on this article  found at www.linux-gamers.net.
Install the dependencies
For Mumble/Murmur 1.1.0 and greater (including SVN), Qt 4.3 is required. For Mumble 1.1.8 or newer, QT 4.4 is required.
For Debian / Ubuntu
The following command makes sure you have the needed libraries and dependencies installed to build Mumble and Murmur from source!
apt-get install qt4-dev-tools libqt4-dev libspeex1 libspeex-dev libboost-dev libasound2-dev libxevie-dev libxevie1 libssl-dev g++ libspeechd-dev libzeroc-ice-dev libpulse-dev slice2cpp libcap-dev
It's recommended to remove the package qt3-dev-tools if installed.
You can also install the libg15-dev libraries for Logitech G15 Keyboard serie.
Now go on to the section #Installing_from_source.
Installing from source
The most generic approach to install mumble under any Linux is to install from source. Either get the current mumble source over git or get the latest tarball release from sourceforge.net.
For compiling from git make sure you've installed git-core (includes git-clone)
apt-get install git-core
git-clone git://mumble.git.sourceforge.net/gitroot/mumble mumble cd mumble/ git-clone http://git.xiph.org/speex.git/ speex
Download the latest tarball release from sf.net http://sourceforge.net/project/showfiles.php?group_id=147372 and extract it:
tar xzfv mumble-x.x.x.tar.gz # (whereas the X are the version numbers of mumble) cd mumble-x.x.x
Compile Mumble and Murmur
For more configuration options on the qmake command read the supplied INSTALL file.
Be sure to have the pre-requisites installed and in place for your linux distribution (see the sections above) before you begin compiling it.
qmake main.pro make
If you want to compile Murmur (Mumble server) only, then type
qmake main.pro CONFIG+=no-client make
Note: If you are using Debian/Ubuntu with both Qt3 and Qt4 installed use the command "qmake-qt4" instead of "qmake"
Text to Speech
For text-to-speech voices you will need to install speech dispatcher and at least a voice. Most distros ship packages for that in their repositories.
cd release ./mumble
