Compile instructions (Ubuntu 14.10) - Git

This page contains only the compilation instructions that are specific to Ubuntu and related Debian-based distributions.

Tested working on: Ubuntu 14.04 LTS and Ubuntu 16.04 LTS

It should also work with the various Ubuntu flavours, including Ubuntu MATE, Ubuntu Studio, Kubuntu and Xubuntu, etc.
It should work on derivatives such as Linux Mint, and it may also work on the corresponding Debian and Debian-derived distributions like Raspian.

Install dependencies

Recent distributions have up-to-date versions of most of the necessary packages are in the default repositories.

sudo apt-get install git cmake g++
sudo apt-get install libasound2-dev portaudio19-dev libmp3lame-dev libsndfile1-dev
sudo apt-get install libssl-dev libpulse-dev libfreetype6-dev libfreetype6

If you get an error message like this while compiling:

Failed to find "GL" in "".

Then try installing these additional libraries:

sudo apt-get install libdrm-dev libgl1-mesa-dev libegl1-mesa-dev

Important Note: It is now necessary to install Qt 5.6, Qt 5.8, or later

MuseScore uses Qt to achieve a consistent look and feel across different platforms (Mac, Windows & Linux). Qt is updated more frequently than any other dependency. Having an out-of-date version of Qt is the most common cause of problems as far reaching as strange window behaviour, keyboard shortcuts not working, or the code failing to compile outright.

If your repository has Qt version 5.6, 5.8, or later, you can get Qt from your repository:

sudo apt-get install libqt4-dev qtbase5-dev qttools5-dev qttools5-dev-tools qtquick1-5-dev \
qtscript5-dev libqt5xmlpatterns5-dev libqt5svg5-dev libqt5webkit5-dev

If your repository does not have 5.6, 5.8, or later then follow these steps to install it:
(Note that having two different versions of Qt installed can cause difficulties. If you installed using "apt-get install" above, then you may want to remove that before following these steps.)

  1. Download the latest version of Qt (currently 5.8) from The file you download is actually an installation script called something like "". (It will be called something different for 32-bit machines).
  2. Move the installer (file you downloaded) to your Home directory and open a terminal window (Ctrl+Alt+T on Ubuntu).
  3. Give the installer execute permissions:
         sudo chmod +x
  4. Run the installer ("sudo" is not required if you choose to install to your Home directory in Step 5):
         sudo ./
  5. Follow the installation wizard and write down the installation directory (default: "/opt/Qt". You can choose somewhere else if you want but make sure it doesn't have spaces anywhere in the path). Finish the install.
  6. In your file browser, navigate to the installation directory and find the path to the Qt "bin" directory. (Mine is "/opt/Qt/5.6/gcc_64/bin". This will be different on different machines.)
  7. Add the "bin" directory to your $PATH environment variable so that MuseScore knows where it is. (Modify the following command with the correct path as appropriate.):
         echo 'export PATH=/opt/Qt/5.6/gcc_64/bin:$PATH' >> ~/.bashrc
  8. Load your new $PATH variable.
         source ~/.bashrc

You can check the Qt installation and version by typing "qmake -version" in a terminal.

If you experience any problems with MuseScore, first check you have the latest copy of the MuseScore source code, and then check you have the latest copy of Qt. Only once you have confirmed this (and done the same for the other dependencies) should you consider creating a bug report in the issue tracker.

Compiling the code

Now follow the generic instructions for compiling on Linux.

The remaining steps on this page are optional. Read them if you experience problems or wish to completely uninstall MuseScore and it's dependencies.

Uninstall dependencies

Remember all the packages installed previously in order to compile MuseScore? Actually, even more were installed because each installed package has its own dependencies. If you don't want them anymore, here's how to remove them.

When you proceed with the installation, apt-get outputs in the terminal the complete list of packages that are to be installed. If you copy this list, the packages can be easily removed later with this command:

sudo apt-get remove --purge LIST

If you did not copy this output and still want to remove all the packages, it's a little more complicated but still feasible. For each command entered, for example:

sudo apt-get install git cmake g++

an entry is added in the following log file: /var/log/apt/history.log. Open it with a text editor and find the relevant entry. Example:

Commandline: apt-get install git cmake g++
Install: libstdc++-4.9-dev:amd64 (4.9.1-15ubuntu1, automatic), libc-dev-bin:amd64 (2.19-10ubuntu1, automatic), g++:amd64 (4.9.1-4ubuntu2), g++-4.9:amd64 (4.9.1-15ubuntu1, automatic), liberror-perl:amd64 (0.17-1.1, automatic), git-man:amd64 (2.1.0-1, automatic), git:amd64 (2.1.0-1), cmake:amd64 (, cmake-data:amd64 (, automatic), linux-libc-dev:amd64 (3.16.0-16.22, automatic), libc6-dev:amd64 (2.19-10ubuntu1, automatic)

Text that must be copied follows the key Install:

libstdc++-4.9-dev:amd64 (4.9.1-15ubuntu1, automatic), libc-dev-bin:amd64 (2.19-10ubuntu1, automatic), g++:amd64 (4.9.1-4ubuntu2), g++-4.9:amd64 (4.9.1-15ubuntu1, automatic), liberror-perl:amd64 (0.17-1.1, automatic), git-man:amd64 (2.1.0-1, automatic), git:amd64 (2.1.0-1), cmake:amd64 (, cmake-data:amd64 (, automatic), linux-libc-dev:amd64 (3.16.0-16.22, automatic), libc6-dev:amd64 (2.19-10ubuntu1, automatic)

To remove these packages:

sudo apt-get remove --purge $(echo "TEXT COPIED ABOVE" | sed -r 's/\s\([^\)]+\),?//g')

IMPORTANT: by doing so, you may remove some Qt packages needed to run MuseScore. The following command should ensure that you have all that is required:

sudo apt-get install libqt5core5a libqt5gui5 libqt5network5 libqt5xml5 libqt5xmlpatterns5 \
libqt5svg5 libqt5printsupport5 libqt5webkit5

Note about lrelease

When we invoke make, a call to the executable lrelease is done during the process. However, it's not the command /usr/bin/lrelease from the package qtchooser but the one from qttools5-dev-tools. That's why the package qttools5-dev-tools is added in the list of dependencies to install. If it was not installed, the following error would occur during the make invocation:

make[4]: Entering directory '/path/to/MuseScore/build.release'
/bin/sh: 1: /usr/lib/x86_64-linux-gnu/qt5/bin/lrelease: not found
CMakeFiles/lrelease.dir/build.make:49: recipe for target 'CMakeFiles/lrelease' failed
make[4]: *** [CMakeFiles/lrelease] Error 127
make[4]: Leaving directory '/path/to/MuseScore/build.release'

and the following during the make install invocation:

CMake Error at share/locale/cmake_install.cmake:36 (FILE):
