Beyond Linux® From Scratch (System V Edition) - Version 9.0

Chapter 25. X Libraries

GTK+-2.24.32

Introduction to GTK+ 2

The GTK+ 2 package contains libraries used for creating graphical user interfaces for applications.

This package is known to build and work properly using an LFS-9.0 platform.

Package Information

GTK+ 2 Dependencies

Required

ATK-2.32.0, gdk-pixbuf-2.38.1 and Pango-1.42.4

Recommended

hicolor-icon-theme-0.17

Optional

Cups-2.2.12, DocBook-utils-0.6.14, gobject-introspection-1.60.2 and GTK-Doc-1.32

[Note]

Note

If gobject-introspection-1.60.2 was installed after ATK-2.32.0, gdk-pixbuf-2.38.1, and/or Pango-1.42.4, those packages will have to be rebuilt before this package can be built.

Installation of GTK+ 2

Install GTK+ 2 by running the following commands: 

sed -e 's#l \(gtk-.*\).sgml#& -o \1#' \
    -i docs/{faq,tutorial}/Makefile.in      &&

./configure --prefix=/usr --sysconfdir=/etc &&

make

To test the results, issue: make check. Note that you must run the tests from a session with X Window Display capability (i.e., not a text-based terminal/console) as the tests attempt to open an X window, and the tests can take an excessively long time. Using an X Window, the tests should take less than 0.3 SBU.

Now, as the root user: 

make install
[Note]

Note

If you installed the package on to your system using a “DESTDIR” method, an important file was not installed and must be copied and/or generated. Generate it using the following command as the root user: 

gtk-query-immodules-2.0 --update-cache

Command Explanations

sed -i 's#l \(gtk-.*\).sgml#& -o \1#' docs/{faq,tutorial}/Makefile.in: If you have DocBook-utils-0.6.14 installed (specifically, if configure finds db2html) then it will try to use it to rebuild some of its HTML documentation and fail due to bugs in some of the Makefiles. This sed fixes the Makefiles.

--enable-gtk-doc: Use this parameter if GTK-Doc is installed and you wish to rebuild and install the API documentation.

Configuring GTK+ 2

Config Files

~/.gtkrc-2.0, /etc/gtk-2.0/gtkrc, and /usr/share/gtk-2.0/gtkrc

Configuration Information

GTK+ 2 themes change the way a GTK+ 2 application looks. A GTK+ 2 icon theme can be used to change the icons that appear on the application's toolbar. If you have installed a GTK+ 2 theme (such as gnome-themes or GTK Engines-2.20.2), a GTK+ icon theme (such as adwaita-icon-theme-3.32.0) you can set your preferences in ~/.gtkrc-2.0: 

cat > ~/.gtkrc-2.0 << "EOF"
include "/usr/share/themes/Glider/gtk-2.0/gtkrc"
gtk-icon-theme-name = "hicolor"
EOF

There are many more themes available at Gnome-Look.org and other places.

Once you've settled on themes you like, you can (as the root user) make them the default system wide: 

cat > /etc/gtk-2.0/gtkrc << "EOF"
include "/usr/share/themes/Clearlooks/gtk-2.0/gtkrc"
gtk-icon-theme-name = "elementary"
EOF

LXAppearance-0.6.3 is a GTK+ 2 application that can help you choose the themes you like.

Installed Libraries: libgailutil.so, libgdk-x11-2.0.so, and libgtk-x11-2.0.so
Installed Directories: /etc/gtk-2.0, /usr/include/{gail-1.0,gtk-2.0,gtk-unix-print-2.0}, /usr/lib/gtk-2.0, /usr/share/doc/gtk+-2.24.32, /usr/share/gtk-2.0, /usr/share/gtk-doc/html/{gail-libgail-util,gdk2,gtk2}, and /usr/share/themes/{Default,Emacs,Raleigh}

Short Descriptions

gtk-builder-convert

converts glade files into XML files which can be loaded with GtkBuilder.

gtk-demo

demonstrates GTK+ 2 functionality and provides code for the examples.

gtk-query-immodules-2.0

collects information about loadable input method modules for GTK+ 2 and writes it to standard output.

gtk-update-icon-cache

creates mmap()able cache files for icon themes. Starting with gtk+-2.24.24, add the flag “--include-image-data” to this command, if you wish previous behavior, with image data in the cache.

libgdk-x11-2.0.so

contains functions that act as a wrapper around the low-level drawing and windowing functions provided by the underlying graphics system.

libgtk-x11-2.0.so

contains functions that provide an API to implement graphical user interfaces.
