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

   $patch -p0 -t -i yap6_2_2_patch_1
   (Patching for FreeBSD or 64bits machines, patch file can be 
   found in libABAC's doc directory)

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

   (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)


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

   FreeBSD users: add --enable-kernel-pfkey --enable-kernel-pfroute 
       --disable-kernel-netlink --disable-tools --disable-scripts 
       --disable-pluto --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.

   Mac OS X users: (Victor) add
       --enable-kernel-pfkey --enable-kernel-pfroute 
       --disable-kernel-netlink --disable-tools --disable-scripts                            --disable-pluto --with-group=wheel
       and also prepend with following if applicable,
       env CPPFLAGS="-I/opt/local/include" LDFLAGS="-L/opt/local/lib" 

   $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 add 
       --with-extra-includes=/usr/local/include
       --with-flex=/usr/local/bin/flex, adjust as needed 
       on ./configure line in addition to --with-strongswan=...

   MAC OS X (victor) users needs to add these flags
       CFLAGS="-I/opt/local/include" CXXFLAGS="-I/opt/local/include"
       CPPFLAGS="-I/opt/local/include" LDFLAGS="-L/opt/local/lib" 
       and --with-flex=/usr/bin/flex, adjust as needed 

   $STRONGSWAN_SRC_DIR=path/to/strongswan-4.6.4
   $STRONGSWAN_LIB_DIR=/usr/local/lib/ipsec
   $./autogen.sh
   $./configure --with-strongswan=$STRONGSWAN_SRC_DIR 
                 --with-strongswan-ld-path=$STRONSWAN_LIB_DIR
   $make 
   $sudo make install
