The LAME package contains an MP3 encoder and optionally, an MP3 frame analyzer. This is useful for creating and analyzing compressed audio files.

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 \
$([ $(uname -m) == "i?86" ] && echo "--enable-nasm") &&
make
To test the results, issue: LD_LIBRARY_PATH=libmp3lame/.libs make test.
Now, as the root user:
make pkghtmldir=/usr/share/doc/lame-3.100 install
First clean the directory:
make distclean
Install lib32-LAME by running the following commands:
CC="gcc -m32" CXX="g++ -m32" \
PKG_CONFIG_PATH=/usr/lib32/pkgconfig \
./configure --prefix=/usr \
--libdir=/usr/lib32 \
--host=i686-pc-linux-gnu \
--enable-mp3rtp \
--disable-static \
--enable-nasm &&
make
To test the results, issue: LD_LIBRARY_PATH=libmp3lame/.libs make test.
Now, as the root user:
make DESTDIR=$PWD/DESTDIR install && cp -vr DESTDIR/usr/lib32/* /usr/lib32 && rm -rf DESTDIR && ldconfig
--enable-mp3rtp: This
switch enables building the encode-to-RTP program.
--disable-static: This
switch prevents installation of static versions of the libraries.
$([ $(uname -m) == "i?86" ] ...: This checks to see if the CPU architecture is ix86, and if so, it passes the parameter explained below to the configure script.
--enable-nasm: This option
enables the use of NASM-2.16.03 to compile optimized assembly
routines for 32-bit x86. This is not enabled for x86_64 as it has
no effect.
