README

Rosegarden v15.12 and Later
===========================

Rosegarden is a MIDI and audio sequencer and musical notation editor for Linux.

  http://www.rosegardenmusic.com/

Please keep an eye on the FAQ for known problems and workarounds:

  http://rosegardenmusic.com/wiki/frequently_asked_questions

When you find bugs, first check whether a newer version of Rosegarden
has been released yet; if not, please continue on to:

  http://rosegardenmusic.com/tutorials/bug-guidelines.html

Release notes can be found in the CHANGELOG.


Build requirements
------------------

For a complete list of build requirements, please see:

http://www.rosegardenmusic.com/wiki/dev:contributing


Installation instructions
-------------------------

In the directory where you found this README file, create a build directory
and compile the code there. Here are the commands to do so:

    mkdir build
    cd build
    cmake .. [-DCMAKE_INSTALL_PREFIX=[PREFIX]] [-DCMAKE_BUILD_TYPE=Debug]
    make
    make install

You can also simply open the CMakeLists.txt file in an IDE (such as QtCreator,
KDevelop or Eclipse) and trigger the build from there.

New starting with 10.02, most of the application data files are bundled in the
rosegarden binary.  The install process will only copy a few files to various
directories under [PREFIX]:

    [PREFIX]/bin                                   application binary
    [PREFIX]/share/icons/hicolor/.../mimetypes     MIME type icons
    [PREFIX]/share/mime/packages                   MIME type configuration
    [PREFIX]/share/applications                    .desktop file
    [PREFIX]/share/icons/hicolor/32x32/apps        application icon

For a debug build, pass the following option to cmake:

    -DCMAKE_BUILD_TYPE=Debug

This will build Rosegarden so that it is useful for debugging, which can
greatly improve our ability to find and correct bugs by allowing Rosegarden
to produce useful stack traces when it crashes.  The debug binary will be
somewhat large: about 200MB as of July 2019.

A debug build results in the use of shared libs and the building of unit
tests.  Use -DBUILD_TESTING=OFF to disable the shared library and unit
tests in a Debug build.

Flags for the C++ compiler can be added via CMAKE_CXX_FLAGS:

    -DCMAKE_CXX_FLAGS="-Werror -Wpedantic"

Support for LIRC (Linux Infrared Remote Control) can be disabled using:

    -DDISABLE_LIRC=1


Runtime requirements
--------------------

In order to be fully functional and provide the optimal user experience,
Rosegarden requires the following external applications.

  - General MIDI soft synth (TiMidity + Freepats or better)
  - LilyPond
  - Okular, Evince, Acroread, MuPDF, ePDFView, or other PDF viewer reachable
    through xdg-open
  - lpr or lp
  - QjackCtl (JACK Audio Connection Kit - Qt GUI Interface)
  - FLAC
  - WavPack
  - DSSI plugins (any your distro carries)
  - LADSPA plugins (any your distro carries)


Running the Unit Tests
----------------------

To run the unit tests, build as follows:

    mkdir build
    cd build
    cmake .. -DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTING=ON
    make

(-DBUILD_TESTING=ON is assumed for a Debug build so it isn't needed.)

Then run the tests with "make test":

    make test


User documentation
------------------

Please see rosegardenmusic.com


SPECIAL NOTES FOR PACKAGE MAINTAINERS
-------------------------------------

As of 10.02 all formerly optional dependencies are now mandatory dependencies.
We've taken this step because it is a real support hassle working through a set
of problems to finally uncover the reason something has broken is due to the
user's distro package being built without a particular feature turned on.

Most major distros already carry everything we depend on, so we don't anticipate
that the build requirements will be a serious irritation for package
maintainers.

Thank you for your cooperation, and thank you for making Rosegarden available to
our users!  If you need to patch Rosegarden for one reason or another in the
course of packaging it, please do keep upstream in the loop at
rosegarden-devel@lists.sourceforge.net or by contacting
michael.mcintyre@rosegardenmusic.com directly.  Thanks!

An older version of the appdata file is kept with the current version in
data/appdata.  It is named rosegarden.appdata-old.xml.
