liblo is a lightweight library that provides an easy to use implementation of the OSC protocol. For more information about the OSC protocol, please see:
The official liblo homepage is here:
liblo is portable to most UNIX systems (including OS X) and Windows. It is released under the GNU Lesser General Public Licence (LGPL) v2.1 or later. See COPYING for details.
To build and install liblo, read INSTALL in the main liblo directory. liblo is configured as a dynamically-linked library. To use liblo in a new application, after
you should install liblo with
so that the liblo library can be located by your application.
To build with MS Visual Studio on Windows, first download and run the
premake4.exe application in the build directory with an argument
describing which IDE you are using. This will generate project and
solution files. See
build/README.md for more details.
Building with CMake
If you prefer the CMake build system, support has been added. Instead
configure step listed in the previous section, create a build
directory and initialize CMake:
mkdir ~/build/liblo cmake ~/source/liblo/cmake <more options..> make
examples for example source code for a simple client and two
lo_server_thread_start()to create a liblo server in an separate thread.
select()to wait for either console input or OSC messages, all in a single thread.
example_client.cuses liblo to send OSC messages to a server.
These examples will work without installing liblo. This is
accomplished by a shell script. For example,
is a shell script that runs the "real" program
examples/.libs/example_client. Because of this indirection, you
example_client with a debugger.
To debug applications using liblo, one option is to include all the liblo source code in the application rather than linking with the liblo library. For more information about this, please see the (libtool manual)1
To compile liblo with debugging flags, use,
liblo was written to support both IPv4 and IPv6, however it has caused various problems along the way because most of the currently available OSC applications like Pd and SuperCollider don't listen on IPv6 sockets. IPv6 is currently disabled by default, but you can enable it using
