How to compile Sonic Visualiser from source
===========================================

(NOTE: Refer also to .travis.yml and .appveyor.yml to how the
continuous-integration processes run a build)

On Windows and Mac it is perhaps easier to build from a checkout of
the Mercurial repository (be sure to update to the appropriate tag if
you need a specific release) than it is to build from an official
Sonic Visualiser source release package. This is because the
repository checkout pulls in some required library builds, while the
source package contains only Sonic Visualiser code.

On Linux it is simpler to build from a source package.


Windows
-------

Use the Qt Creator IDE with either the MinGW compiler (for 32-bit
builds) or Visual C++ (for 64-bit builds).

For details, see the wiki page at

https://code.soundsoftware.ac.uk/projects/sonic-visualiser/wiki/WindowsBuild30


MacOS
-----

Build from the command line, but do not use the configure script.

Install Qt5, either via Homebrew or from the official installer.

 * If you are building from a repository checkout, install Poly/ML via
Homebrew (`brew install polyml`) and run `./repoint install` before
proceeding. This isn't necessary when building from an official source
release.

 * If you are building from an official source release, make sure the
following required dependencies are available, whether installed using
Homebrew or some other method: (This isn't necessary when building
from a repository checkout)

REQUIRED        Rubber Band Library     http://www.breakfastquay.com/rubberband/
REQUIRED        libsndfile              http://www.mega-nerd.com/libsndfile/
REQUIRED        libsamplerate           http://www.mega-nerd.com/SRC/
REQUIRED        FFTW3                   http://www.fftw.org/
REQUIRED        bzip2 library           http://www.bzip.org/
REQUIRED        Sord and Serd libraries http://drobilla.net/software/
REQUIRED        Cap'n Proto             http://capnproto.org/

Then run `qmake -r sonic-visualiser.pro` and `make`. (You may need to
provide the full path to the correct `qmake` executable for the
version of Qt you want to build with.)


Linux
-----

$ ./configure && make && make install

The following additional libraries are required or optional:

REQUIRED        Qt v5                   http://www.qt.io/
REQUIRED        Rubber Band Library     http://www.breakfastquay.com/rubberband/
REQUIRED        libsndfile              http://www.mega-nerd.com/libsndfile/
REQUIRED        libsamplerate           http://www.mega-nerd.com/SRC/
REQUIRED        FFTW3                   http://www.fftw.org/
REQUIRED        bzip2 library           http://www.bzip.org/
REQUIRED        Sord and Serd libraries http://drobilla.net/software/
REQUIRED        Cap'n Proto             http://capnproto.org/
REQUIRED        MAD mp3 decoder         http://www.underbit.com/products/mad/
REQUIRED        Oggz and fishsound      http://xiph.org/oggz/
REQUIRED        Opus                    http://www.opus-codec.org/

Optional        liblo OSC library       http://www.plugin.org.uk/liblo/
Optional        JACK                    http://www.jackaudio.org/
Optional        PortAudio v19           http://www.portaudio.com/
Optional        PulseAudio              http://www.pulseaudio.org/

Although JACK, PortAudio, and PulseAudio are individually optional,
you will need to have at least one of them in order to get any audio
playback.  Usually JACK is preferred on Linux, with PulseAudio as a
backup, and PortAudio is used elsewhere.

On Linux, you will need the ALSA libraries (used for MIDI).

For Cap'n Proto you will need v0.6 or newer.

For the rest, if you happen to be using a Debian-based Linux, you
probably want to apt install something like the following packages:

build-essential libbz2-dev libfftw3-dev libfishsound1-dev libid3tag0-dev liblo-dev liblrdf0-dev libmad0-dev liboggz2-dev libopus-dev libopusfile-dev libpulse-dev libsamplerate-dev libsndfile-dev libsord-dev libxml2-utils portaudio19-dev qt5-default libqt5svg5-dev raptor2-utils librubberband-dev capnproto libcapnp-dev git mercurial autoconf automake libtool mlton

If you are building Sonic Visualiser from a repository checkout, then
the configure script will use Repoint to obtain further checkouts of
various dependencies. You will need to have a SML compiler installed
for this to work, such as SML/NJ, MLton, or Poly/ML - hence the
presence of mlton in the Debian package list above. This is not
necessary when building from an official Sonic Visualiser source
release.
