Install Swift/PyECLib dependencies on OSX

swift-ecdeps-osx.sh

#!/bin/bash
## swift-ecdeps-osx.sh
## https://gist.github.com/briancline/364d539e0e230b92adae
##
## This script is meant to be used on OSX as a quick and easy way to download,
## build, and install gf-complete, Jerasure, and liberasurecode to any prefix
## path you specify. These are typically what you may want if you're working
## with OpenStack Swift for a quick and dirty EC-friendly test run.
##
## The Xcode command line tools are required in order for this to work.
##
## The prefix defaults to $HOME/eclocal, and underneath it, you'll find:
##  ECPREFIX
##  |-ECPREFIX/{bin,include,lib,share} -- as needed by the various libraries
##  `-ECPREFIX/src -- where all the code gets cloned and compiled
##
## Once it's finished, it'll spew out an export line you can use if you need to
## to have OSX look in some non-OSX location for the dynamically-linked modules
## installed by this script.
##
## Note that you don't necessarily need to install to /usr/local or some other
## system path; this is what the -p option and the export line at the very
## bottom are for.
##
## If you encounter issues, feel free to post them in a comment on the gist.

## ISA-L *really* didn't like the gf-complete libs on OSX...but if it did, this is what you might do
# brew install yasm
# curl -LO https://01.org/sites/default/files/downloads/intelr-storage-acceleration-library-open-source-version/isa-l-2.14.0.tar.gz
# tar -zxf isa-l-2.14.0.tar.gz
# pushd isa-l-2.14.0
#   ./configure --prefix=${ECPREFIX}
#   make -j${ECMAKEJOBS}
#   make install
# popd


## You'll want this before you `make test` liberasurecode below
export DYLD_LIBRARY_PATH=${ECPREFIX}/lib/


git clone https://bitbucket.org/tsg-/liberasurecode.git
pushd liberasurecode
  ./autogen.sh
  ./configure --prefix=${ECPREFIX}
  make -j${ECMAKEJOBS}
  make test
  make install
popd  # liberasurecode

popd  # $ECPREFIX/src

Master did not work and produced the same error seen here.

Checking out v1.1.0 worked. (line 123)

If someone came here: brew install liberasurecode works well

Huh, TIL I don't/didn't get notifications for my gists. Anyways, yes, definitely use the brew formula that now exists. This script was meant primarily to get bleeding-edge liberasurecode builds and not so much for stable releases.
