Chapter 24. X Libraries

Pango-1.26.0

Introduction to Pango

The Pango package contains the libpango libraries. These are useful for the layout and rendering of text.

This package is known to build and work properly using an LFS-6.5 platform.

Package Information

Pango Dependencies

Required

GLib-2.22.0 and one of cairo-1.8.8 or X Window System or Fontconfig-2.7.3

cairo is not required to build Pango, but it is highly recommended that you install cairo before building Pango. If you don't build Pango with a cairo backend, then GTK+-2 will not build.

Optional

LibThai

Optional (If cairo is Not Installed)

X Window System

Optional (To Rebuild the API Documentation)

GTK-Doc-1.11

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/pango

Installation of Pango

Install Pango by running the following commands: 

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

To test the results, issue: make check. You can install GTK-Doc-1.11 if you wish to test the documentation section of the test suite. Also, the “testboundries” test could fail if you have LibThai installed.

Now, as the root user: 

make install

Command Explanations

--sysconfdir=/etc: This switch installs the configuration files into /etc instead of /usr/etc.

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

--disable-static: This switch prevents the static libraries from being built.
