Compiling Hydrogen V0.9.4 / V0.9.5 / V0.9.6

Linux

These are the instructions for compiling the Hydrogen versions 0.9.4, 0.9.5 and 0.9.6 (all based on QT4) on a debian-based distribution. Hydrogen runs on all kinds of linux distribution, but then the package names and installation tools will differ.

Required libraries

QT4	libqt4-dev
ALSA	libasound-dev
SndFile	libsndfile-dev
JACK	libjack-dev
LRDF	liblrdf-dev
FLAC++	libflac++-dev
TAR	libtar-dev
LASH	liblash-dev
ZLIB	zlib1g-dev

Build steps

1. Install the required libraries:

apt-get install subversion libqt4-dev g++ libasound2-dev libjack-dev liblrdf0-dev libflac++-dev libtar-dev libsndfile1-dev 

If you want to use lash, install additionally

liblash-dev 

If you want to use rubberband, install additionally

librubberband-dev 

If you want to use OSS, install additionally

oss4-dev 

For portaudio / portmidi:

libportaudio-dev libportmidi-dev

NOTE: make sure you are installing version 19 (on some Ubuntu systems V18 is the default)

If you're using portaudio / portmidi v19, make sure you apply the portaudio/portmidi patches (see below).

This is just an example for debian based systems. The package names may vary for other distributions.

Now install the build system. If you're using hydrogen < 0.9.6, you have to install SConstruct:

apt-get install scons  

For hydrogen 0.9.6 and above, install cmake:

apt-get install cmake  

2. Get the sourcecode:

cd /usr/src
svn co http://svn.assembla.com/svn/hydrogen/trunk hydrogen

3. Apply portaudio / portmidi patches (only if you want to use portaudio / portmidi v19)

cd /usr/src/hydrogen
patch -p0 < patches/portaudio.patch 
patch -p0 < patches/portmidi.patch

if the patches dir is empty this simply means that there are no patches to apply

4. Compile and install hydrogen:

For hydrogen < 0.9.6:

cd /usr/src/hydrogen
scons
su -c "scons install"

If you want to use lash, portmidi or portaudio be sure to enable it by appending " lash=1","portaudio=1" or "portmidi=1" to the scons command

For hydrogen >= 0.9.6:

cd /usr/src/hydrogen
./build.sh m

5. Build a debian package

As an alternative to "scons install" you can build a debian package. This makes it easier to remove hydrogen from your system.

apt-get install fakeroot debhelper build-essential
cd /usr/src/hydrogen/linux
fakeroot dpkg-buildpackage

The package appears in /usr/src/hydrogen and can be installed with dpkg ( dpkg -i package_name )
