shairport-sync/LIBSOXR.md

The Raspbian image at the time of writing is the May 2016 version, with the release date of 2016-05-10. It does not include libsoxr, but it is available as a package via apt-get.

Alternatively, libsoxr is very easy to compile. Here are very brief instructions to download, compile and install it:

• Install cmake. This is used in the building of libsoxr:

sudo apt-get install cmake

• Download the libsoxr source:

git clone git://git.code.sf.net/p/soxr/code libsoxr

• cd into the libsoxr directory and start the build process:

cd libsoxr
./go

Be patient! This takes a long time on a Raspberry Pi -- it looks like it gets stuck around 40% or 50%, but it will finish if you let it.

Having compiled libsoxr, it must now must be installed:

cd Release
sudo make install

Finally, for Shairport Sync to be able to locate libsoxr-dev during compilation, you need to tell ld to catalogue it:

sudo ldconfig -v

That's it. Now you can select the --with-soxr option when you're building Shairport Sync.
