  Build Instructions for Windows NetSurf                      13 February 2010
--------------------------------------------------------------------------------

  This document provides instructions for building the Windows version
  of NetSurf and provides guidance on obtaining NetSurf's build
  dependencies.

  Windows NetSurf has been tested on Wine and Vista.


  Building and executing NetSurf
================================

  The windows netsurf port uses the MinGW (Minimal GNU on Windows)
  system as its build infrastructure. This allows the normal netsurf
  build process to be used.

  The method outlined here to create executables cross compiles
  windows executable from a Linux OS host.

  First of all, you should examine the contents of Makefile.defaults
  and enable and disable relevant features as you see fit by creating
  a Makefile.config file.  Some of these options can be automatically
  detected and used, and where this is the case they are set to such.
  Others cannot be automatically detected from the Makefile, so you
  will either need to install the dependencies, or set them to NO.
  
  You should then obtain NetSurf's dependencies, keeping in mind which
  options you have enabled in the configuration file.  See the next
  section for specifics.
  
  Once done, to build windows NetSurf on a UNIX-like platform, simply run:

      $ export MINGW_PREFIX=i586-mingw32msvc-
      $ export MINGW_INSTALL_ENV=/usr/i586-mingw32msvc/
      $ make TARGET=windows

  If that produces errors, you probably don't have some of NetSurf's
  build dependencies installed. See "Obtaining NetSurf's dependencies"
  below. Or turn off the complaining features in a Makefile.config
  file. You may need to "make clean" before attempting to build after
  installing the dependencies.

  You will need the libgnurx-0.dll from /usr/i586-mingw32msvc/bin/
  copied next to the exe and the windows/res directory available, also
  next to the executable.

  Run NetSurf by executing it:

      $ wine NetSurf.exe

  The staticaly linked binary which is generated may be several
  megabytes in size, this can be reduced by stripping the binary.

      $ i586-mingw32msvc-strip NetSurf.exe 


  Obtaining NetSurf's build dependencies
========================================

  Package installation
----------------------

  Debian-based OS:

  The mingw cross compilation tools are required. These can be
  installed as pakages on Debian/Ubuntu systems:

      $ sudo apt-get install mingw32 mingw32-binutils mingw32-runtime

  These provide a suitable set of compilers and headers including the win32 API.

  The includes and associated libraries are installed in
  /usr/i586-mingw32msvc/ Which is where the build system will include
  files from by default. The packages at time of writing only target
  32bit windows builds.

  Other:

  For other OS the apropriate packages and environment must be installed.

  Base libraries
----------------

  Unlike other OS the base libraries and their dependancies need to be
  built and installed.

  The instructions given here assume you will be installing on a
  Debian derived OS using the mingw32 packages. The libraries should
  be unpacked and built from a suitable temporary directory.

  zlib:
  
      $ apt-get source zlib1g
      $ cd zlib-1.2.3.3.dfsg
      $ CC=i586-mingw32msvc-gcc AR=i586-mingw32msvc-ar RANLIB=i586-mingw32msvc-ranlib CFLAGS="-DNO_FSEEKO" ./configure --prefix=/usr/i586-mingw32msvc/
      $ make
      $ sudo make install

  libiconv:

      $ wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
      $ tar -zxf libiconv-1.13.1.tar.gz
      $ cd libiconv-1.13.1
      $ ./configure --prefix=/usr/i586-mingw32msvc/ --host=i586-mingw32msvc --disable-shared
      $ make
      $ sudo make install

  regex:

      $ wget http://downloads.sourceforge.net/project/mingw/User%20Contributed/regex/mingw-regex-2.5.1/mingw-libgnurx-2.5.1-src.tar.gz?use_mirror=ignum

      $ ./configure --prefix=/usr/i586-mingw32msvc/ --host=i586-mingw32msvc
      $ make
      $ sudo make install

  openssl:

      $ tar -zxf openssl-0.9.8l.tar.gz

  The NetSurf project's libraries
---------------------------------

  The NetSurf project has developed several libraries which are required by
  the browser. These are:

  LibParserUtils  --  Parser building utility functions
  LibWapcaplet    --  String internment
  Hubbub          --  HTML5 compliant HTML parser
  LibCSS          --  CSS parser and selection engine
  LibNSGIF        --  GIF format image decoder
  LibNSBMP        --  BMP and ICO format image decoder
  LibROSprite     --  RISC OS Sprite format image decoder

  To fetch each of these libraries, run the following commands:

      $ svn co svn://svn.netsurf-browser.org/trunk/libparserutils
      $ svn co svn://svn.netsurf-browser.org/trunk/libwapcaplet
      $ svn co svn://svn.netsurf-browser.org/trunk/hubbub
      $ svn co svn://svn.netsurf-browser.org/trunk/libcss
      $ svn co svn://svn.netsurf-browser.org/trunk/libnsgif
      $ svn co svn://svn.netsurf-browser.org/trunk/libnsbmp
      $ svn co svn://svn.netsurf-browser.org/trunk/librosprite

  To build and install these libraries.

  Ensure the MINGW_INSTALL_ENV variable is correctly set.

      $ export MINGW_INSTALL_ENV=/usr/i586-mingw32msvc/

 Then simply enter each of their directories and run:
  
      $ make TARGET=windows PREFIX=/usr/i586-mingw32msvc/
      $ sudo make TARGET=windows PREFIX=/usr/i586-mingw32msvc/ install

  Resources
-----------

  The windows resources may be rebuilt. Currently there is 1 object
  file included in the svn distribution of NetSurf that could be
  manually compiled

      $ cd windows/res
      $ i586-mingw32msvc-windres resource.rc -O coff -o resource.o
