%general-entities; ]> Liba52 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. &lfs121_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &liba52-md5sum; Download size: &liba52-size; Estimated disk space required: &liba52-buildsize; Estimated build time: &liba52-time; Optional djbfft Editor Notes: Install liba52 by running the following commands: ./configure --prefix=/usr \ --mandir=/usr/share/man \ --enable-shared \ --disable-static \ CFLAGS="${CFLAGS:--g -O3} -fPIC" && make To test the results, issue: make check. Now, as the root user: make install && cp liba52/a52_internal.h /usr/include/a52dec && install -v -m644 -D doc/liba52.txt \ /usr/share/doc/liba52-&liba52-version;/liba52.txt CFLAGS="${CFLAGS:--g -O3} -fPIC": This appends -fPIC to CFLAGS but use -g -O3 (the default of this package) instead of an empty string when CFLAGS is not set. This is needed to compile liba52 without runtime text relocation. Runtime text relocation is prohibited on x86_64 so -fPIC is strictly required. On 32-bit x86 runtime text relocation is allowed but it's insecure and it may waste physical RAM, so -fPIC is still better. 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.
