Installation of Liba52

Install liba52 by running the following commands:

./configure --prefix=/usr \
            --mandir=/usr/share/man \
            --enable-shared \
            --disable-static \
            CFLAGS="-g -O2 $([ $(uname -m) = x86_64 ] && echo -fPIC)" &&

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 \

Command Explanations

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.
