Read the developer handbook for a complete build walkthrough and a list of dependencies.
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 https://github.com/musescore/MuseScore/releases, and then from your download directory type:
tar xzf MuseScore-x.x.x.tar.gz
cd MuseScore-x.x.x
To compile MuseScore, type:
make release
If something goes wrong, then remove the whole build subdirectory with make clean and start new with make release.
To start MuseScore, type:
./build.release/mscore/mscore
The Start Center window will appear on every invocation until you disable that setting via the "Preferences" dialog.
To install to default prefix using root user, type:
sudo make install
A debug version can be built by doing make debug instead of make release.
To run the debug version, type:
./build.debug/mscore/mscore
See mtest/README.md or https://musescore.org/en/developers-handbook/testing for instructions on how to run the test suite.
