Packages

See Code Structure on Wiki

Building

Read the Compilation section of the MuseScore Wiki for a complete build walkthrough and a list of dependencies.

Getting sources

If using git to download repo of entire code history, type:

git clone https://github.com/musescore/MuseScore.git
cd MuseScore

Otherwise, you can just download the latest source release tarball from the Releases page, and then from your download directory type:

tar xzf MuseScore-x.x.x.tar.gz
cd MuseScore-x.x.x

To compile MuseScore for release, type:

cmake -P build.cmake -DCMAKE_BUILD_TYPE=Release

If something goes wrong, append the word "clean" to the above command to delete the build subdirectory:

cmake -P build.cmake -DCMAKE_BUILD_TYPE=Release clean

Then try running the first command again.

Running

To start MuseScore, type:

cmake -P build.cmake -DCMAKE_BUILD_TYPE=Release run

Or run the compiled executable directly.

Debug Build

A debug version can be built and run by replacing -DCMAKE_BUILD_TYPE=Release with -DCMAKE_BUILD_TYPE=Debug in the above commands.

If you omit the -DCMAKE_BUILD_TYPE option entirely then RelWithDebInfo is used by default, as it provides a useful compromise between Release and Debug.

Testing

See the Unit tests section of the MuseScore Wiki for instructions on how to run the test suite.

Code Formatting

Run ./hooks/install.sh to install a pre-commit hook that will format your staged files. Requires that you install uncrustify.

If you have problems, please report them. To uninstall, run ./hooks/uninstall.sh.
