Introduction to Gdk Pixbuf

The Gdk Pixbuf package 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-11.0 platform.

Installation of Gdk Pixbuf

Install Gdk Pixbuf by running the following commands: 

mkdir build &&
cd build &&

meson --prefix=/usr --buildtype=release --wrap-mode=nofallback .. &&
ninja

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

Now, as the root user: 

ninja 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

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

--wrap-mode=nofallback: This switch prevents meson from iusing subproject fallbacks for any dependency declarations in the build files, stopping it downloading any optional dependency which is not installed on the system.
