Building & Installing REX-Ray on macOS

1. Install GNU Make if gmake is not available:

   brew install make

2. Clone the repository:

   git clone https://github.com/codedellemc/rexray

3. Build it:

   cd rexray
   gmake

   If the build was successful you should see something like this:

   The rexray binary is 52MB and located at:
   
   ./rexray

4. Copy it somewhere useful:

   mkdir -p ~/bin
   cp ./rexray ~/bin

5. Be sure to include ~/bin in $PATH:

   cat <<EOT >> ~/.bashrc
   # Path: ~/bin" >> ~/.bashrc
   if [ -s "$HOME/bin" ]; then
       export PATH="$HOME/bin:$PATH"
   fi
   EOT

6. Run your .bashrc again:

   source ~/.bashrc

7. Verify:

   cd ~
   rexray

And you're done!

This is good tutorial, except missing the command "export GOOS=darwin", before running "gmake". By default, it builds the binary for Linux system. The env variables GOOS and GOARCH will determine which OS and architecture the binary will be built for.
