Build Instructions for GTK NetSurf 13 October 2008
--------------------------------------------------------------------------------
This document provides instructions for building the GTK version of NetSurf
and provides guidance on obtaining NetSurf's build dependencies.
GTK NetSurf has been tested on Debian, Ubuntu, Fedora 8, FreeBSD, NetBSD and
Solaris 10.
Building and executing NetSurf
=================================
First of all, you should examine the contents of Makefile.config and enable
and disable relevant features as you see fit. 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 GTK NetSurf on a UNIX-like platform, simply run:
$ make
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 Makefile.config. You may need to "make clean"
before attempting to build after installing the dependencies.
Run NetSurf by executing the "netsurf" shell script:
$ ./netsurf
This script makes it easy to run the nsgtk binary from the build tree. It
sets up some environment variables which enable NetSurf to find its
resources.
If you are packaging NetSurf, see the PACKAGING-GTK document.
Obtaining NetSurf's build dependencies
========================================
Many of NetSurf's dependencies are packaged on various operating systems.
The remainder must be installed manually. Currently, some of the libraries
developed as part of the NetSurf project have not had official releases.
Hopefully they will soon be released with downloadable tarballs and packaged
in common distros. For now, you'll have to make do with svn checkouts.
Package installation
----------------------
Debian-like OS:
$ apt-get install libglade2-dev libcurl3-dev libxml2-dev libmng-dev
$ apt-get install librsvg2-dev lemon re2c
Fedora:
$ yum install libglade2-devel curl-devel libxml2-devel libmng-devel
$ yum install librsvg2-devel lcms-devel re2c
Other:
You'll need to install re2c, a tool which builds the CSS lexer, and the
development resources for libglade2, libcurl3, libxml2, libmng and librsvg.
Note that if you don't require MNG or JNG image support, NetSurf can be
configured to use libpng instead of libmng. If you wish to do this, install
the libpng development package instead.
Libnsbmp
----------
NetSurf has its own library for decoding and rendering BMPs, ICOs, etc.
You can check it out from svn://svn.netsurf-browser.org/trunk/libnsbmp
To build and install it:
$ sudo make install
Libnsgif
----------
NetSurf has its own library for decoding and rendering GIFs. You can check
it out from svn://svn.netsurf-browser.org/trunk/libnsgif
To build and install it:
$ sudo make install
Hubbub
--------
NetSurf can use Hubbub, the project's HTML parser, instead of using libxml2's
HTML parser. To build this, you will also require libparserutils. Firstly,
check out libparserutils from;
svn://svn.netsurf-browser.org/trunk/libparserutils
and do the usual "sudo make install". Once this is built and installed, you
can check out and build Hubbub. Check out hubbub from;
svn://svn.netsurf-browser.org/trunk/hubbub
and again do the usual "sudo make install".
Librosprite
-------------
NetSurf uses James Shaw's librosprite for rendering RISC OS Sprite files on
non-RISC OS platforms. The Makefile will automatically use librosprite if
it is installed. You can disable it entirely by editing Makefile.config.
To build librosprite, check out from svn://svn.rjek.com/jshaw/libsprite/trunk
Build and install it:
$ sudo make install
Optionally, specify an install prefix:
$ PREFIX=/path/to/install make install
Libhpdf
---------
NetSurf can use Haru PDF to enable PDF export and printing in GTK. This
is currently enabled by default, and cannot be auto-detected by the Makefile.
If you wish to disable it, do so by editing Makefile.config.
Haru PDF can be obtained from http://libharu.sourceforge.net/, although we
currently depend on features that the official version does not have. You
can obtain our patched version from the following Subversion address until
the patches are accepted upstream;
svn://svn.netsurf-browser.org/branches/libharu/adamblokus
Lemon
-------
If your distribution does not package 'lemon' (Fedora doesn't) then you'll
need to download it and build it yourself. You may find it comes with the
SQLite packages (SQLite's parser is built with lemon). If not, try this:
$ mkdir -p /usr/local/share/lemon
$ wget http://www.sqlite.org/cvstrac/getfile/sqlite/tool/lemon.c
$ wget -O /usr/local/share/lemon/lempar.c http://www.sqlite.org/cvstrac/getfile/sqlite/tool/lempar.c
$ sed -e's!lempar.c!/usr/local/share/lemon/lempar.c!' lemon.c > lem.c
$ gcc -o /usr/local/bin/lemon lem.c
General requirements
----------------------
NetSurf requires at minimum GTK 2.12. Earlier versions will not work. It also
depends on Cairo for rendering, but you should have this already with
versions of GTK 2.12 or later.
This will pull in loads of things, like all the GTK dev libraries, the PNG
and JPEG libraries, colour management libraries, zlib, OpenSSL etc that
NetSurf also depends on.
