For Java installation instructions, see doc/java_install.

Prior to building libabac 
   you may need to install flex, bison, and GNU readline library
   you must install YAP and libstrongswan
   Please check doc/dependencies for other software dependencies

Download yap-6.2.2 from www.dcc.fc.up.pt
    http://www.dcc.fc.up.pt/~vsc/Yap/yap-6.2.2.tar.gz

$./configure --enable-dynamic-loading --enable-use-malloc=yes
$make
$make library
$sudo make install_library

(Note: If you ever run into the OOOPS message when installing Yap, 
manually clear out all traces of Yap from your /usr/local especially
/usr/local/share)


You can also install yap on Ubuntu using
$ sudo apt-get install yap

Download strongswan-4.6.4 from strongswan.org:
    http://download.strongswan.org/strongswan-4.6.4.tar.bz2


FreeBSD users: add --with-group=wheel to strongswan ./configure

Linux users: add --disable-gmp --enable-openssl to strongswan ./configure
to avoid long credential creation times. The entropy sources
libstrongswan uses by default gather entropy slowly on Linux.  These
flags allow it to gather entropy from the same sources as openssl, which
is noticeably faster. The internal strongswan libraries and plugins
are installed in /usr/local/lib/ipsec by default unless 
--with-ipseclibdir and --with-plugindir are set otherwise.

$ tar xjvf strongswan-4.6.4.tar.bz2
$ cd strongswan-4.6.4
$ # see note above about configure flags
$ ./configure --enable-monolithic 
$ cd src/libstrongswan
$ make && sudo make install

Be sure to make note of the directory into which you've untarred
strongswan-4.6.4.tar.bz2. You will use this in the next step.

BUILDING LIBABAC

FreeBSD users will need to install flex-2.5.35 or greater from ports and
use --with-flex=/usr/local/bin/flex --with-extra-includes=/usr/local/include
on ./configure in addition to --with-strongswan

$ STRONGSWAN_SRC_DIR=path/to/strongswan-4.6.4
$ STRONGSWAN_LIB_DIR=path/to/strongswan-ipseclibdir (or /usr/local/lib/ipsec)
$ ./configure --with-strongswan=$STRONGSWAN_SRC_DIR --with-strongswan-ld-path=$STRONSWAN_LIB_DIR
$ make 
$ sudo make install
