liba52 is a free library for decoding ATSC A/52 (also known as AC-3) streams. The A/52 standard is used in a variety of applications, including digital television and DVD.
This package is known to build and work properly using an LFS-11.2 platform.

Install liba52 by running the following commands:
./configure --prefix=/usr \
--mandir=/usr/share/man \
--enable-shared \
--disable-static \
CFLAGS="${CFLAGS:--g -O2} $([ $(uname -m) = x86_64 ] && echo -fPIC)" &&
make
To test the results, issue: make check.
Now, as the root user:
make install &&
cp liba52/a52_internal.h /usr/include/a52dec &&
install -v -m644 -D doc/liba52.txt \
/usr/share/doc/liba52-0.7.4/liba52.txt
CFLAGS="-g -O2 ...: This
sets CFLAGS to -g -O2 (which is the default) but then on x86_64
adds -fPIC. This is needed to compile liba52 on x86_64.
--disable-static: This
switch prevents installation of static versions of the libraries.
cp liba52/a52_internal.h ...: Copying this header file into /usr/include/a52dec allows some other programs (such as xine-lib) to compile and link against a system installed liba52.
