Liquidsoap 1.4.4
Forewords
Installing liquidsoap can be a difficult task. The software relies on
a up-to date OCaml
compiler, as well as a bunch of
OCaml
modules and, for most of them, corresponding C
library dependencies.
Our recommended way of installing liquidsoap is via opam. opam
can take care
of install the correct OCaml
compiler, optional and
required dependencies as well as system-specific package
dependencies.
The opam
method is described in details in the documentation. We recommend that any
interested user head over to this link to install the software via
opam
.
The following of this document describes how to install the software
via its configure
script and is intended either for system
administrators or package maintainers.
Dependencies
Below is a list of dependencies, mostly OCaml libraries. Optional
libraries provide extra features. They need to be detected by the
configure
script.
Most of the libraries are developed by the Savonet project and, in addition to being available through traditional distribution channels, are bundled in the liquidsoap-<version>-full.tar.bz2 tarballs for easier builds.
Libraries not developed by Savonet are:
- camlimages
- camomile
- gd4o
- ocaml-pcre
- ocaml-magic
- ocaml-sdl
- yojson

Installing via configure
The build processus starts with by invoking the
configure
script:
% ./configure
If you want a complete installation of liquidsoap, enabling a
production use of liquidsoap as a daemon, you should pass
--with-user=<login>
and
--with-group=<group>
options to indicate which
user/group you have created for liquidsoap.
Then, build the software:
% make
You can also generate the documentation for liquidsoap:
% make doc
It will generate the HTML documentation, including a version of the scripting API reference corresponding to your configuration.
Then, you may proceed to the installation. You may need to be root for that.
% make install
This will not install files such as /var/log/liquidsoap
unless you have provided a user/group under which liquidsoap should be
ran. This behavior can be overridden by passing
INSTALL_DAEMON="yes"
(useful for preparing binary
packages).
If you need to run liquidsoap as a daemon, you can then have a look at liquidsoap-daemon.
