INSTALLATION INSTRUCTIONS
To build and install the libfec libraries, simply say
./configure
make
make test (optional)
make install (as root)
By default, "make install" puts the libfec libraries in
/usr/local/lib, the include files in /usr/local/include, and the
manual page in /usr/local/man.
You may have an old version of the GNU assembler that cannot handle
the relatively new SSE2 mnemonics. Update your version of the GNU
"binutils" package.
You may obtain the latest binutils package through your normal
distribution channels or from:
http://sources.redhat.com/binutils/
TESTING THE FEC LIBRARY
After running the ./configure script, optional tests can be built and
run as follows:
make test
"make test" tests each routine, using the SIMD versions as
appropriate, verifying correct operation and estimating Viterbi
decoding speeds. These tests should always succeed unless something is
broken.

ADDENDUM
The original libfec did not know about x86-64. This caused builds to break on that CPU family.
This version contains a (lightly modified) working build. It does not contain optimized assembly instructions for x86-64, however.
Also, when building under x86-64, it is necessary to tell libfec about your host. This can easily be accomplished by passing the --build flag to ./configure. For example, if the standard ./configure contained here thinks that my host is i386-apple-darwin15.0.0, then I will call `./configure --build=x86_64-apple-darwin15.0.0`.
