Compile instructions (Ubuntu) - Git
This page contains only the compilation instructions that are specific to Ubuntu and related Debian-based distributions.
Tested working on: Ubuntu 16.04 LTS, 18.04 LTS, and 20.04 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.
Recent distributions have up-to-date versions of most of the necessary packages in the default repositories.
sudo apt-get install git cmake g++ sudo apt-get install libasound2-dev portaudio19-dev libmp3lame-dev libsndfile1-dev libportmidi-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 as of November 2020 necessary to install Qt 5.15, or later to compile the master branch. 5.9 or later is necessary for 3.x with plugins.
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 Having an out-of-date version of Qt is the most common cause of problems as far reaching as strange window behavior, keyboard shortcuts not working, or the code failing to compile outright.
If your repository has Qt version 5.15 (or 5.9 for 3.x), or later, you can get Qt from your repository:
sudo apt-get install qtbase5-dev qttools5-dev qttools5-dev-tools qtwebengine5-dev \ qtscript5-dev libqt5xmlpatterns5-dev libqt5svg5-dev libqt5webkit5-dev \ qtbase5-private-dev libqt5x11extras5-dev qtdeclarative5-dev qtquickcontrols2-5-dev
Might need these too:
sudo apt-get install qml-module-qtquick-controls2 qml-module-qtquick-window2 qml-module-qtquick2 qml-module-qtgraphicaleffects qml-module-qtqml-models2 libqt5quicktemplates2-dev qtquickcontrols2-5-dev libqt5x11extras5 libqt5x11extras5-dev libqt5networkauth5 libqt5networkauth5-dev qtbase5-private-dev
If musescore compiles but you get a warning message while compiling about QuickTemplates2, you may get an empty Palette in Musescore. If so, check to see if "/usr/lib/x86_64-linux-gnu/cmake/Qt5QuickTemplates2" exists. If not, try copying:
And replace all mentions of "QuickControls2" with "QuickTemplates2".
If your repository does not have 5.15 (5.9), 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.)
- Download the latest version of Qt (5.15 as of November 2020) from https://www.qt.io/download-open-source. The file you download is actually an installation script called something like "qt-unified-linux-x64-2.0.3-online.run". (It will be called something different for 32-bit machines).
- Move the installer (file you downloaded) to your Home directory and open a terminal window (Ctrl+Alt+T on Ubuntu).
- Give the installer execute permissions:
sudo chmod +x qt-unified-linux-x64-2.0.3-online.run
- Run the installer ("sudo" is not required if you choose to install to your Home directory in Step 5):
- Choose the "Custom installation" option and make sure "Qt WebEngine" is included in the list of packages at Qt > Qt 5.15.x. 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.
- In your file browser, navigate to the installation directory and find the path to the Qt "bin" directory. (Mine is "/opt/Qt/5.8/gcc_64/bin". This will be different on different machines.)
- Add the "bin" directory to your $PATH environment variable so that MuseScore knows where it is. (Modify the following command with the correct path as appropriate.):
echo 'export PATH=/opt/Qt/5.8/gcc_64/bin:$PATH' >> ~/.bashrc
- Load your new $PATH variable.
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 Compile instructions (Linux & BSD) - Git.
The remaining steps on this page are optional. Read them if you experience problems or wish to completely uninstall MuseScore and it's 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:
Start-Date: START DATE OF INSTALLATION
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 (184.108.40.206-0ubuntu5), cmake-data:amd64 (220.127.116.11-0ubuntu5, automatic), linux-libc-dev:amd64 (3.16.0-16.22, automatic), libc6-dev:amd64 (2.19-10ubuntu1, automatic)
Upgrade: MAY BE THERE BUT IT'S NOT RELEVANT
End-Date: END DATE OF INSTALLATION
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 (18.104.22.168-0ubuntu5), cmake-data:amd64 (22.214.171.124-0ubuntu5, 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
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: 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: *** [CMakeFiles/lrelease] Error 127 make: 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): file INSTALL cannot find "/path/to/MuseScore/share/locale/mscore_af.qm". Call Stack (most recent call first): share/cmake_install.cmake:43 (INCLUDE) cmake_install.cmake:45 (INCLUDE) Makefile:62: recipe for target 'install' failed make: *** [install] Error 1 make: Leaving directory '/path/to/MuseScore/build.release' Makefile:92: recipe for target 'install' failed make: *** [install] Error 2
