Compiling software is the process of turning human-readable source code into machine code a computer can execute. Compiling Mixxx is fairly straightforward on Linux. The steps below outline what to do.
Mixxx relies on several external libraries for various features.
The Mixxx build scripts still rely on SCons 2 and don't work with SCons 3 and Python 3. If your distribution (Fedora 27, …) already comes with SCons 3 the build will fail when following the instructions.
As a workaround you can simply install SCons 2 side by side::
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 g++ git scons libqt4-dev libqt4-sql-sqlite libportmidi-dev \ libopusfile-dev libshout-dev libtag1-dev libprotobuf-dev protobuf-compiler \ libusb-1.0-0-dev libfftw3-dev libmad0-dev \ portaudio19-dev libchromaprint-dev librubberband-dev libsqlite3-dev \ libid3tag0-dev libflac-dev libsndfile-dev libupower-glib-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 sudo apt-get install libqt4-opengl libqt4-svg libqt4-xmlpatterns libqt4-sql # Linux Mint/KDE sudo apt-get install libx11-dev libqt4-dev libgl-dev libqt4-opengl-dev # Linux Mint/KDE
NOTE: Updated these for Mixxx 2.0 and Ubuntu 15.10, if this does not work on recent versions of Debian please split this section up.
TODO: Please consider putting these instructions into version control so they can be kept in sync with a particular version or branch.
If your distribution is Raspian, you can install them by running:
sudo apt-get remove libtag1-vanilla sudo apt-get install g++ git scons libqt4-dev libqt4-sql-sqlite libportmidi-dev \ libopusfile-dev libshout3-dev libtag1-dev libprotobuf-dev protobuf-compiler \ libusb-1.0-0-dev libfftw3-dev libmad0-dev \ portaudio19-dev libchromaprint-dev librubberband-dev libsqlite3-dev \ libid3tag0-dev libflac-dev libsndfile1-dev libupower-glib-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 sudo apt-get install libmp3lame-dev
If the libopusfile-dev is not avaliable for you, download, build and install:
sudo apt-get remove g++ g++-4.7 sudo apt-get autoremove sudo apt-get install g++-5 ln /usr/bin/g++-5 /usr/bin/g++ scons -c && scons -j 2 opengles=1 staticlibs=1 optimize=portable
You must build in Raspberry pi 3.
Raspberry pi 2 i had the error:
Error: open CFI at the end of file; missing .cfi_endproc directive
It seems a memory limitation.

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:
su [Enter the password for the user "root" at the prompt] dnf groupinstall "Development Tools" dnf install gcc-c++ upower-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.
If you are still running as root from installing packages, return to using your normal unprivileged user account (press Ctrl + D or run
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.)
git clone -b 2.1 https://github.com/mixxxdj/mixxx.git
git clone https://github.com/mixxxdj/mixxx.git
git clone -b 1.12 https://github.com/mixxxdj/mixxx.git(the git branch for 2.0 is still called 1.12)
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.
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, which is /usr/local. If you only want to install Mixxx for your user, you can specify a location in your home directory such as ~/local
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 multi-core CPUs. You can check how many threads your CPU can run simultaneously with the
lscpu command (look for the
CPU(s) field in the output). Setting more threads than your CPU can handle will decrease performance.
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
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
To compile on a Raspberry Pi, use the arguments:
optimize=native opengles=1 machine=armhf
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 build with Qt5 instead of Qt4, use the scons option
qt5=1. This is currently experimental. It may help with scaling the GUI on high resolution screens.
On Debian, Clang is provided as a package with a version number attached. Using 3.6 as an example, install it like this:
sudo apt-get install clang-3.6
To compile Mixxx using Clang 3.6, before running
export CC=clang-3.6 export CXX=clang++-3.6
You can now use clang-specific SCons options.
If scons can't find installed dependencies, try
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.
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.
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*/
