Introduction to FLAC

FLAC is an audio CODEC similar to MP3, but lossless, meaning that audio is compressed without losing any information.

Installation of FLAC

Install FLAC by running the following commands:

patch -Np1 -i ../flac-1.1.2-xmms_plugin_fix-1.patch &&
LIBS=-lm ./configure --prefix=/usr &&

If you have Valgrind version 3.0.0 or higher installed and you plan on running the test suites after passing the --enable-valgrind-testing parameter to configure, you need to issue the following command to change some test scripts:

sed -i -e "s/logfile-fd/log-fd/" `grep -lr logfile-fd test/*sh`

To test the results, issue: make check. This test suite will take quite a while. Note that if you passed the --enable-exhaustive-tests and --enable-valgrind-testing parameters to configure and then run the test suite, it will take a very long time (up to 300 SBUs) and use about 375 MB of disk space.

Now, as the root user:

make install

Command Explanations

LIBS=-lm ./configure --prefix=/usr: libFLAC uses a function from the math library but is not linked with libm. Passing the environment variable to configure satisfies this dependency.

--enable-sse: This option is off by default and should be set on if your machine has SSE capability. One way to find out if you have SSE is to issue cat /proc/cpuinfo and see if sse is listed in the flags.
