readme.osx-macports

KPP can be compiled on OSX using MacPorts (https://www.macports.org/) to supply 
a more unix-compatible version of gcc (as well as flex). To do this follow the
instructions below:

1) Install Xcode and the Xcode Command Line Tools, and then install macports.
See here for more guidance: https://www.macports.org/install.php

2) Install Flex and GCC:
port install gcc49
port install flex

3) Replace the Makefile.defs and cflags.guess files with the provided alternative 
osx-macports files:
cp Makefile.defs.osx-macports Makefile.defs
cp cflags.guess.osx-macports cflags.guess

These files are configured assuming that you've installed macports in the default,
system-wide, location (/opt/local/). If you have installed macports anywhere else
you will have to modify them to use your own path. Also, the gcc compiler has a
version specific binary name - so this may need changing at a future date as new
versions are released.


4) Compile KPP by following the rest of the instructions in "readme".


This installation has be tested on OSX 10.10.5, with MacPorts 2.4.2, flex 2.6.4 
and gcc version 4.9.4. It should work with minimal changes on other OSX systems
though.
