Mac Development Environment
===========================

* Xcode - If you only have the Xcode command line tools installed, and not the full Xcode UI, you may see build errors like this:

        native:
             [exec] xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

    This can be fixed by installing the full Xcode from App Store. Verify your installation by launching Xcode once and running `xcodebuild` from the command line.


* Various build tools are also required. You can install these using [brew](http://brew.sh).

        $ brew install autoconf automake libtool
        
    If you are missing these tools, when you build you are likely to see errors like those below:
      
        native:
             [exec] Generating configure
             [exec] ./autogen.sh: line 2: exec: autoreconf: not found

    or
    
        [exec] Can't exec "aclocal": No such file or directory at /usr/local/Cellar/autoconf/2.69/share/autoconf/Autom4te/FileUtils.pm line 326.
        [exec] autoreconf: failed to run aclocal: No such file or directory

    or
        
        [exec] configure.ac:41: error: possibly undefined macro: AC_PROG_LIBTOOL

    or
    
        native:

            [exec] configure: WARNING: unrecognized options: --enable-static, --disable-shared, --with-pic
            [exec] configure: error: cannot find install-sh, install.sh, or shtool in
