Hi all

I’m trying to build libav to get hold of avconv.

I’m following the following “recipe” that hopefully should work:

curl -O curl -O https://libav.org/releases/libav-11.3.tar.gz
tar xjf libav-11.3.tar.gz
cd libav-11.3
./configure
make install
But on the ./configure step the process fails:

Mac-JJJ:libav-11.3 jjarava$ ./configure
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
yasm/nasm not found or too old. Use --disable-yasm for a crippled build.

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
libav-tools at libav.org mailing list or IRC #libav on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
nasm is installed in the system:

Mac-JJJ:tmp-avconv jjarava$ nasm -v
NASM version 0.98.40 (Apple Computer, Inc. build 11) compiled on Feb 24 2015
Am attaching the config.log file as requested

Regards,

– Javier
