ERROR: libmp3lame >= 3.98.3 not found

Question

I am installing ffmpeg utility, but I am facing libmp3lame >= 3.98.3 not found not found error. I am able to find lame-3.99.5-1.el6.rf.x86_64.rpm and lame-libs-3.98.4-1.el6.nux.x86_64.rpm but installing these are not solving the problem. I am not able to find libmp3lame rpm to install.

Can anyone help me here?

If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the [email protected] mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.log" produced by configure as this will help solve the problem.

Answer 1

I just experienced this problem. I had lame v3.99.5 installed, but ffmpeg configure was giving ERROR: libmp3lame >= 3.98.3 not found.

In addition to --extra-ldflags, I had to specify --extra-cflags. So, the configure line was:

./configure [...] --enable-libmp3lame [...] --extra-ldflags=-L/usr/local/lib --extra-cflags=-I/usr/local/include

What worked for me was building lame from source. Download lame from here: https://sourceforge.net/projects/lame/files/lame/3.99/, then extract and install:

tar -zxvf lame-3.99.5.tar.gz 
cd lame-3.99.5
./configure
make
sudo make install

Check to see where libmp3lame.a is:

locate libmp3lame.a

Its probably in /usr/local/lib.

Now when you go to configure ffmpeg, try adding that path to the end of your ./configure string. For me it made the difference. e.g.:

--extra-ldflags=-L/usr/local/lib

For configure troubleshooting see the ffbuild/config.log in the ffmpeg source directory.

In my case it had missing references to libmath functions, even if -lm was set in host_extralibs.

For a quick-fix add -lm to the configure script:

enabled libmp3lame        && require "libmp3lame >= 3.98.3" lame/lame.h lame_set_VBR_quality -lmp3lame -lm
