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)" && make
To test the results, issue: make check.
Now, as the
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 option stops it
installing the static version of the library.
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.
