The LAME package contains an MP3 encoder and optionally, an MP3 frame analyzer. This is useful for creating and analyzing compressed audio files.
Apply a patch to fix multiple build failures and settings:
patch -Np1 -i ../lame-4.0-upstream_fixes-1.patch
Prevent the source code directory from being mistakenly hardcoded as a shared library search path in the installed programs:
sed -i -e 's/^\(\s*hardcode_libdir_flag_spec\s*=\).*/\1/' configure
Install LAME by running the following commands:
./configure --prefix=/usr \
--enable-mp3rtp \
--disable-static &&
make
Now, as the root user:
make pkghtmldir=/usr/share/doc/lame-4.0 install
Install lib32-LAME by running the following commands:
make distclean &&
CC="gcc -m32" CXX="g++ -m32" \
PKG_CONFIG_PATH=/usr/lib32/pkgconfig \
./configure --prefix=/usr \
--libdir=/usr/lib32 \
--host=i686-pc-linux-gnu \
--enable-mp3rtp \
--disable-static \
--enable-nasm &&
make
Now, as the root user:
make DESTDIR=$PWD/DESTDIR install && cp -vr DESTDIR/usr/lib32/* /usr/lib32 && rm -rf DESTDIR && ldconfig
Run ./configure --help for a full list of options.
--enable-mp3rtp: This
switch enables building the encode-to-RTP program.
--disable-static: This
switch prevents installation of static versions of the libraries.
--enable-nasm: This option
enables the use of NASM-3.02 to compile optimized assembly routines
for 32-bit. This is not enabled for x86_64 as it has no effect.
--disable-decoder: Use this option if
you have not installed mpg123-1.33.6.
