Quick build using MinGW
-----------------------

This is a quick description on how to build ntop on Win2k/XP using
the MinGW toolchain. It is assumed you are familiar with MinGW and
Windows programming in general. ntop requires many different libraries
installed. This file does *not* tell you how to install those; it only
briefly where to get them.

If you're unable to build ntop from the sources, then you're probably
better off using the Windows binary available from
  http://sourceforge.net/project/showfiles.php?group_id=17233


Obtaining Ntop
--------------

This was last tested against the 21-May 2004 CVS version of ntop 3.0.
Available via these hairy commands:

  cvs -d :pserver:anonymous@cvs.ntop.org:/export/home/ntop login
  cvs -d :pserver:anonymous@cvs.ntop.org:/export/home/ntop co ntop
  cvs -d :pserver:anonymous@cvs.ntop.org:/export/home/ntop logout

use "ntop" when asked for a password.

Note: the CVS-server is notoriously slow! Use the sources (ntop*.tgz)
      at http://sourceforge.net/project/showfiles.php?group_id=17233
      if you don't mind using "old" sources.


Building Ntop
-------------

Prerequisites:

  1) WinPCAP developer's pack available from
     http://winpcap.polito.it/

  2) GD-chart package available from
     http://www.fred.net/brv/chart/

  3) GD library (which is needed by GD-chart) is available from
     http://www.boutell.com/gd/

  4) PNG library for Portable Network Graphics images. Available from
     http://gnuwin32.sourceforge.net/packages/libpng.htm

  5) Zlib compression library available from
     http://www.gzip.org/zlib/

  6) GNU database library available from
     http://sourceforge.net/project/showfiles.php?group_id=7382&package_id=12648

  7) OpenSSL library is needed if "USE_SSL = 1" in Makefile.MingW. Available from
     http://www.openssl.org/

  8) Various tools; rm, sed, mkdir and man2html. The latter is only needed
     to generate ntop.html.


Steps

  1) Install and build all prerequisites.

  2) Edit ntop's Makefile.MingW and change the following root-values:

     "PCAP_ROOT"     to the base directory of WinPCAP.
     "GDCHART_ROOT"  to the base directory of GD-chart.
     "GD_ROOT"       to the base directory of GD library.
     "PNG_ROOT"      to the base directory of libpng.
     "ZLIB_ROOT"     to the base directory of Zlib.
     "GDBM_ROOT"     to the base directory of GNU database manager.
     "OPENSSL_ROOT"  to the base directory of OpenSSL.


  3) Build the make dependencies by
     > make -f Makefile.MingW depend


  4) Build ntop itself
     > make -f Makefile.MingW

     If after some time you see "Welcome to ntop", it has succeeded and
     you're ready to use it. Otherwise review the Makefile.MingW and look
     for missing packages.


Installing Ntop
---------------

The Makefile.MingW uses static libraries for all packages except OpenSSL.
This increases it's size, but makes maintenance and installation easier.
In fact, there should be no need to install ntop; simply run it from the
base directory. Only make sure the needed OpenSSL DLLs are somewhere in
your PATH or in ntop's directory itself.
