Dependencies
============

Anytun can be built by using either libgcrypt or the openssl-crypto library. 
The latter is more performant in most cases but there are some license 
issues when using this library.

Linux
-----

using libgcrypt:
  libgcrypt11-dev

using ssl crypto lib:
  libssl-dev

common:
  build-essential
  libboost-serialization1.35-dev
  libboost-thread1.35-dev
  libboost-system1.35-dev
  libboost-regex1.35-dev
  asciidoc (only for manpage)


Freebsd
-------

using libgcrypt:
   security/libgcrypt

using ssl crypto lib:
   <nothing here>

common:
   devel/boost
   devel/gmake


Windows
-------
OpenSSL
 Developer:

 Runtime Only:

Boost 1.35: 
	http://www.boostpro.com/download/boost_1_35_0_setup.exe

  As it can take some time to install everything from boost here is a 
  complete list of libraries which have to be installed in order to build anytun:
   
   * Serialization
   * Thread 
   * date_time
   * System
   * regex

Microsoft Visual C++ 2008 Redistributable Package (x86):

Installation
============

Getting the source via subversion:
----------------------------------
svn co http://svn.anytun.org/anytun/trunk anytun
cd anytun

Building from source
--------------------

using libgcrypt:

 # cd src
 # ./configure
 # make

using ssl crypto library:

 # cd src
 # ./configure --use-ssl-crypto
 # make


Notes: 
  - try './configure --help' for further information
  - if using openssl pre 0.9.8 you have to disable passphrase
    because openssl had no SHA256 implementation prior to this
    version
  - on FreeBSD you have to use gmake instead of make


Errors:
=======

Note: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)
Cannot open TUN/TAP dev /dev/anytun0: No such file or directory (errno=2)

Solution: Enabling tun/tap device
------------------------------------

modprobe tun
cd /dev
./MAKEDEV tun

edit /etc/modules and add the line
tun
to load the module automatically


Installing
==========

# sudo make install

This will install anytun under the --prefix defined with configure.


Uninstalling
============

# sudo make remove

This removes everytthing except for the config files

# sudo make purge

This also removes the config files
