Install the dependencies

Mumble 1.2.3 or newer requires at least Qt 4.6.

Debian or Ubuntu

We do not recommend building Mumble on Debian 5 ("Lenny") or older. Please update to Debian 6 ("Squeeze") or newer. You may still be able to build it by playing with package sources to include only required packages from Squeeze, but that is not a supported solution.

You need to make sure you have the needed libraries and dependencies installed to build Mumble and Murmur from source. This can be done in one of those ways:

Icons oxygen 48x48 status task-attention.png
Warning: Note that since Debian 10 the libg15daemon-client-dev package has been removed from their repository. You'll have to use the no-g15 config option or follow G15 support


If your distribution provides packages of the 1.2.x versions, it is sufficient to just run:

apt-get build-dep mumble

Otherwise, you need to install some development packages manually:

apt-get install build-essential pkg-config qt4-dev-tools libqt4-dev libspeex1 \
                libspeex-dev libboost-dev libasound2-dev libssl-dev g++ \
                libspeechd-dev libzeroc-ice-dev ice-slice libpulse-dev slice2cpp \
                libcap-dev libspeexdsp-dev libprotobuf-dev protobuf-compiler \
                libogg-dev libavahi-compat-libdnssd-dev libsndfile1-dev \
                libg15daemon-client-dev libxi-dev 

It is recommended to remove the package qt3-dev-tools if installed.

Warning: For Ice-3.4.1 you will need libexpat1-dev and libdb4.6++-dev, which conflicts with newer packages.


Since Mumble Snapshots aren't available in the repository, you need to install development packages manually:

apt-get install build-essential pkg-config qt5-default qttools5-dev-tools libqt5svg5-dev \
                libboost-dev libasound2-dev libssl-dev \
                libspeechd-dev libzeroc-ice-dev libpulse-dev \
                libcap-dev libprotobuf-dev protobuf-compiler \
                libogg-dev libavahi-compat-libdnssd-dev libsndfile1-dev \
                libg15daemon-client-dev libxi-dev 

Now go on to the section Getting the source.



dnf builddep mumble


Icons oxygen 48x48 status task-attention.png
Warning: The build has been tested on a Docker builder using the official Fedora image. You may need to install more dependencies on a standard installation.
dnf install make gcc gcc-c++ which qt5* protobuf-compiler protobuf-devel openssl-devel \
            libsndfile-devel alsa-lib-devel avahi-compat-libdns_sd-devel libXi-devel \
            speech-dispatcher-devel flac-devel libogg-devel libvorbis-devel libcap-devel

Finding missing dependencies

If the build fails even after installing the dependencies listed above, you'll need to find out that package name on your own. I use dnf provides to hunt these things down. This command is best learned through a demonstration, so here's an example Mumble build that's missing a dependency:

 $ qmake CONFIG+="no-g15 no-ice" -recursive
 $ make
 ... omitted lots of build info ....
 mumble_pch.hpp:117:20: fatal error: dns_sd.h: No such file or directory
 compilation terminated.
 make[2]: *** [release/mumble.gch/c++] Error 1
 make[2]: Leaving directory `/home/dafrito/src/mumble/src/mumble'
 make[1]: *** [release] Error 2
 make[1]: Leaving directory `/home/dafrito/src/mumble/src/mumble'
 make: *** [sub-src-mumble-make_default-ordered] Error 2

The key line in the above is the "fatal error: dns_sd.h: No such file or directory" This will always be very close to the bottom of make's output. We'll need to install that header file somehow, so we'll try looking in Fedora's repos first. yum provides lets us search for packages that provide a specified file. In this case, we'll look for packages that give us dns_sd.h

 $ dnf provides '*/dns_sd.h' # be careful not to forget the quotes or the wildcard here
 avahi-compat-libdns_sd-devel-0.6.30-4.fc16.i686 : Header files for the Apple Bonjour mDNSResponder compatibility libraries
 Repo        : fedora
 Matched from:
 Filename    : /usr/include/avahi-compat-libdns_sd/dns_sd.h
 Filename    : /usr/include/dns_sd.h

This lets us know that avahi-compat-libdns_sd-devel provides the needed header, so now we can install that package

 $ dnf install avahi-compat-libdns_sd-devel
 .. lots of installation ..

And now we can try building Mumble again using make. If you're missing multiple packages, then you'll probably need to repeat the above process to satisfy any missing dependencies. If Mumble still doesn't build, you may be able to discern which feature is causing problems and avoid building it entirely using a CONFIG+=no-* option. You can look at INSTALL for details on what features can be toggled off. For example. qmake CONFIG+=no-server -recursive will omit the server component of Mumble.

ICE Support

The package libICE-devel isn't available in the Fedora repositories anymore. You need to compile Ice from source or build Mumble without Ice support using "CONFIG+=no-ice".

Arch Linux

At the time of writing, Murmur is in pacman's repositories, but doesn't support Ice because the zeroc-ice component isn't in the repositories. To build an Ice-capable Murmur, you'll need to setup and be familiar with the Arch Build System, which is outside the scope of this document.

Next, I grabbed the zeroc-ice tarball, and extracted it into my ABS directory. I edited the PKGCONFIG to remove all the Java bindings for Ice - because I won't be needing them and didn't want to wait for the Java stuff to install as a dependency, if you feel you might want/need Java/Ice later on, then leave it in - then built and installed the package as per the instructions in the ABS walkthrough.

Grab the Murmur-ice tarball and extract it in your ABS directory. Build, and if you want the stable release, install the resulting package with pacman.

If you want to build from git, you should have most of the required runtime dependencies, but you'll also want these for building:

pacman -S base-devel git

At this point you should be able to continue on to Installing from Source.

G15 Support

Some distributions don't package G15 support. In that case the build will fail with a missing "g15daemon_client.h" header file.

You can avoid building G15 support using a qmake CONFIG+=no-g15. However, if you'd like to build this, it is possible to install it manually by building the G15 stuff from source. Be warned that this process can be a little tricky since you'll be building and installing RPMs manually, as well as building another component from source.

Finally, the G15 daemon will need to be built from scratch:

 $ svn co g15daemon-code
 $ cd g15daemon-code/g15daemon
 $ autoreconf -i
 $ ./configure
 $ make
 $ make install

At this point, if all other dependencies are met, you should be able to build Mumble with G15 support.


These instructions are meant to guide you on how to build the G15 library itself on Fedora. On other distributions you'll have to adapt accordingly.

First, install some dependencies that you'll need later:

 $ dnf install libdaemon-devel libusb-devel libtool svn rpm-build autoconf automake libtool

Then pick up the G15 library that's already been packaged (this was linked to in the Bugzilla ticket):

 $ wget
 $ rpmbuild --rebuild libg15-1.2.7-1.fc16.src.rpm

It's possible you'll run into missing dependencies at this point. Follow the yum provides process outlined above to find out what you'll need to install.

 $ cd ~/rpmbuild/RPMS
 $ ls
 noarch  x86_64 i686
 $ cd `uname -p` # equates to x86_64 on my system, may be i686 on yours
 $ dnf localinstall libg15*

Getting the source

The best way to get Mumble's source is using Git. You can also download the latest ZIP package from GitHub.


For compiling from Git make sure you've installed Git:

apt-get install git

Next, download the Mumble source (this may take a minute. At this time of writing, 2016, November 4th, the size is 43.39 MiB):

git clone git:// mumble
cd mumble
git submodule init
git submodule update

To use the current (development) branch, which you most likely do:

git checkout --track -b master origin/master

To use the 1.3.x (stable) branch:

git checkout --track -b 1.3.x origin/v1.3.x

If you want to update your local branch, make sure you're still in the main git directory ('mumble' in the above example) and use this command:

git pull

Zip package

Download the latest zip archive from GitHub, extract it and fetch the submodules:

unzip -d mumble
cd mumble
git submodule init
git submodule update

Compiling Mumble and Murmur

From Qt Creator

Installing Qt Creator

On Debian or Ubuntu:

apt-get install qtcreator

On Fedora:

dnf install qt-creator

On Arch Linux:

pacman -S qtcreator

Building and running Mumble

Open the project file located in the main directory, choose the build preset you want to use and press on the green arrow that seems like a play button. Mumble will start automatically once it's ready.

From the terminal

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.

Building Mumble

qmake -recursive

If you want to compile only the Mumble server (aka Murmur), then type:

qmake -recursive CONFIG+=no-client
Icons oxygen 48x48 actions view-pim-notes.png
The available CONFIG options are explained in INSTALL.

Running Mumble

cd release

Build errors

one or more PCH files were found, but they were invalid

This error means that you have attempted to compile before and now you probably changed some configuration. This lead to the PCH (pre-compiled header file) to be invalid. In order to solve this issue, run make clean before trying to compile again.

Running Murmur

See the dedicated page: Running Murmur

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.
