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
cdinto thelibsoxrdirectory 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.
