Compiling on Linux

Compiling software is the process of turning human readable source code into machine readable code that a computer can execute. Compiling Mixxx is fairly straightforward on Linux. The steps below outline what to do in order to compile Mixxx.

Install build dependencies

Mixxx relies on several external libraries for various features.

Debian / Ubuntu

If your distribution is Debian based (such as Ubuntu), you can install them by running:

sudo apt-get build-dep mixxx 
sudo apt-get install git scons libqt4-dev libqt4-sql-sqlite libportmidi-dev libopus-dev libshout-dev libtag1-dev libprotobuf-dev protobuf-compiler libvamp-hostsdk3 vamp-plugin-sdk libusb-1.0-0-dev libfftw3-dev libmad0-dev portaudio19-dev libchromaprint-dev librubberband-dev libsqlite3-dev
sudo apt-get install libjack-dev libjack0 portaudio19-dev # because of Bug #1464120
sudo apt-get install libfaad-dev libmp4v2-dev # required for M4A support


On Fedora, enable the RPMFusion package repository. You only need to enable the free repository; the nonfree repository is not necessary for Mixxx. Then run:

dnf groupinstall "Development Tools"
dnf install scons gcc-c++ sqlite-devel rubberband-devel libchromaprint-devel
dnf builddep mixxx


For other distributions, you will need to install the following through your distribution's package manager. On most distributions, you will also need the corresponding -dev or -devel packages for each package. If you cannot find a package listed here that starts with “lib”, try searching for the package name without the “lib” prefix.

Get Mixxx

If you are still running as root from installing packages, return to using your normal unprivileged user account (press Ctrl + D or run exit).

If you want to compile Mixxx, you'll need to download the source code. Either grab the source for the latest release from our downloads page, or checkout a snapshot from our git repository: (See Using Git for more details & options.)

To update to the latest version of a git branch, enter (cd into) the directory you cloned the git repository into and run git pull. See Using Git for more details.

Compile and install

Once you have the source code, change to the newly created “mixxx” directory (run cd mixxx). Mixxx uses the SCons build system rather than the more common GNU autotools and GNU make. Running scons -h in the “mixxx” directory shows a complete list of build flags if you'd like to customize. To compile without any special options, as a regular user, run:

scons prefix=INSTALLATION_DIRECTORY -j NUMBER_OF_CPU_CORES optimize=native

Change INSTALLATION_DIRECTORY to the location you want to install Mixxx to. If you want to install Mixxx for all users of the OS, you do not need to specify a prefix and can leave it as the default /usr/local. If you only want to install Mixxx for your user, you can specify a location in your home directory such as ~/local

Running scons will take some time, depending on the speed of your computer. Specifying NUMBER_OF_CPU_CORES will tell scons to run that many threads at a time while compiling. This speeds up compilation on multicore CPUs.

Once Mixxx has compiled, if you set the prefix options for scons to a directory that your normal user does not have write access to, run

sudo scons prefix=INSTALLATION_DIRECTORY install

to install it. If you set the prefix to a directory your user does have write access to, then you do not need sudo before scons. The prefix option must be the same as before or scons will recompile Mixxx before installing it.

If you want to be able to run Mixxx on different types of CPUs, change optimize=native to optimize=portable

Build with m4a/AAC file support

If you want to play m4a files, add faad=1 to your scons commands above. This requires the libraries faad2 and libmp4v2 (or libmp4) to be installed.


To uninstall a copy of Mixxx that you compiled, cd into the directory where you ran scons before, then run:

scons -c prefix=INSTALLATION_DIRECTORY install

INSTALLATION_DIRECTORY must be the same as that used when compiling and installing. If you needed to use sudo to install, also use sudo to uninstall.

Clean up

If scons fails with mysterious errors about not finding dependencies that you know are installed, it may be using outdated cached information to look for the dependencies. This can happen after upgrading your GNU/Linux distribution. To resolve this, try running scons -c and recompiling Mixxx.

Run without installing

If you want to just run this copy without installing, from the same directory, run: (WARNING this uses and may overwrite user-wide configs)

./mixxx --resourcePath res/

To also run from a different settings folder use:

./mixxx --resourcePath res/ --settingsPath /*the folder you like*/
