Pango-1.50.12
Introduction to Pango
Pango is a library for laying out
and rendering text, with an emphasis on internationalization. It
can be used anywhere that text layout is needed, though most of the
work on Pango so far has been done
in the context of the GTK+ widget
toolkit.
This package is known to build and work properly using an LFS 11.3
platform.

Installation of Pango
Install Pango by running the
following commands:
mkdir build &&
cd build &&
meson --prefix=/usr --buildtype=release --wrap-mode=nofallback .. &&
ninja
If you have Gi-DocGen-2023.1 installed and wish to build
the API documentation for this package, issue:
sed "/docs_dir =/s@\$@ / 'pango-1.50.12'@" -i ../docs/meson.build &&
meson configure -Dgtk_doc=true &&
ninja
To test the results, issue: ninja
test. Two tests, test-font and test-layout are known to fail.
Now, as the root user:
ninja install
Command Explanations
--buildtype=release:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-Dintrospection=disabled: Use this
switch if you do not want to use gobject-introspection-1.74.0.
--wrap-mode=nofallback:
This switch prevents meson from using subproject
fallbacks for any dependency declarations in the build files,
stopping it downloading any optional dependency which is not
installed on the system.
