Beyond Linux® From Scratch - Version 7.7

Chapter 25. X Libraries

gdk-pixbuf-2.31.2

Introduction to Gdk Pixbuf

The Gdk Pixbuf is a toolkit for image loading and pixel buffer manipulation. It is used by GTK+ 2 and GTK+ 3 to load and manipulate images. In the past it was distributed as part of GTK+ 2 but it was split off into a separate package in preparation for the change to GTK+ 3.

This package is known to build and work properly using an LFS-7.7 platform.

Package Information

Required

GLib-2.42.1, libjpeg-turbo-1.4.0, libpng-1.6.16 and LibTIFF-4.0.3

Recommended

Xorg Libraries (Many GTK+ applications require gdk-pixbuf-xlib).

Optional (Required if building GNOME)

gobject-introspection-1.42.0

Optional

JasPer-1.900.1 and GTK-Doc-1.21

Installation of Gdk Pixbuf

Install Gdk Pixbuf by running the following commands: 

./configure --prefix=/usr --with-x11 &&
make

To test the results, issue: make check. The tests make a heavy use of the disk. Two tests fail.

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 should be copied and/or generated. Generate it using the following command as the root user: 

gdk-pixbuf-query-loaders --update-cache

Command Explanations

--with-x11: This switch enables building of the Gdk Pixbuf X11 library which is needed for many packages.

--with-libjasper: If you've installed JasPer-1.900.1 and you want Gdk Pixbuf to use it to compile a JPEG2000 image loader, pass this switch to configure.

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

Short Descriptions

gdk-pixbuf-csource

is a small utility that generates C code containing images, used for compiling images directly into programs.

gdk-pixbuf-query-loaders

collects information about loadable modules for Gdk Pixbuf and writes it to the default cache file location, or to stdout.

contains functions used to load and render images.

libgdk_pixbuf_xlib-2.0.so

contains functions used to manipulate images and interfaces with Xlib.
