Updating to latest ubuntu version - msds updating services
Some distributions (for example, current Ubuntu) package Audacity with MP3 encoding and FFmpeg (or Libav) already linked dynamically to the relevant system libraries.
Most Linux distributions have some sort of package manager that fetches software packages from the Internet and installs them for you.
In Ubuntu 11.10 and later the default package manager is the "Ubuntu Software Center".
It is often most convenient to install the "Ubuntu Restricted Extras" as this includes LAME, FFmpeg and other useful media encoding/decoding tools.
It is recommended to use a shared build, but Audacity will also work with a static build.
To build FFmpeg, obtain the source code from the FFmpeg project.
To build libav, obtain the source code from the libav project.
Configure the build with --enable -shared so that it builds the necessary shared object library (.so) files.If you download a pre-built library, this might be either a "shared" or "static" build.A static build consists of a single libavformat library, whereas a shared build has at least three libraries (libavformat, libavcodec and libavutil).If required, you can also configure to enable or disable particular encoding/decoding libraries.When you build Audacity from our source code, it should link to the installed FFmpeg headers.sudo apt-get update sudo apt-get install gcc-4.6 sudo apt-get install g -4.6 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 20 sudo update-alternatives --install /usr/bin/g g /usr/bin/g -4.6 20 sudo update-alternatives --config gcc sudo update-alternatives --config g is the general procedure.
