Read the developer handbook 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
cd MuseScore

Else can just download the latest source release tarball from, and then from your download directory type:

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

Release Build

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:


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

Debug Build

A debug version can be built by doing make debug instead of make release.

To run the debug version, type:



See mtest/ or for instructions on how to run the test suite.
