Introduction to LAME

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

This package is known to build and work properly using an LFS-7.7 platform.

Package Information

LAME Dependencies


Dmalloc, Electric Fence, libsndfile-1.0.25 and NASM-2.11.06

User Notes:

Installation of LAME

First, fix a compiler error introduced by gcc-4.9.0 on 32-bit machines:

case $(uname -m) in
   i?86) sed -i -e '/xmmintrin\.h/d' configure ;;

Install LAME by running the following commands:

./configure --prefix=/usr --enable-mp3rtp --disable-static &&

To test the results, issue: make test.

Now, as the root user:

make pkghtmldir=/usr/share/doc/lame-3.99.5 install

Command Explanations

sed -i -e '/xmmintrin\.h/d' configure : with gcc-4.9.0 and above, the compiler issues an error on 32-bit machines, while compiling xmm_quantize_sub.c. The error message is: error: inlining failed in call to always_inline '_mm_loadu_ps'. This sed makes it appear as if xmmintrin.h is not present. Do not use this on other versions of gcc.

--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: Enable the use of NASM-2.11.06 to compile optimized assembly routines.
