Building

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 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

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.

Running

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.

Installing

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:

./build.debug/mscore/mscore

Testing

See mtest/README.md or the developer handbook for instructions on how to run the test suite.

The new script testing facility is also available to create your own automated tests. Please try it out!

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.
