Chapter 12. Preparing Xorg and Support Libraries

Cairo-1.18.4

Introduction to Cairo

Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System, Win32, image buffers, PostScript, PDF and SVG. Experimental backends include OpenGL, Quartz and XCB file output. Cairo is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available (e.g. through the X Render Extension). The Cairo API provides operations similar to the drawing operators of PostScript and PDF. Operations in Cairo include stroking and filling cubic Bézier splines, transforming and compositing translucent images, and antialiased text rendering. All drawing operations can be transformed by any affine transformation (scale, rotation, shear, etc.)

This package is known to build and work properly using an LFS 12.4 platform.

Cairo Dependencies

Required

libpng-1.6.50 and Pixman-0.46.4

Recommended

Fontconfig-2.17.1, GLib-2.86.2 (required for most GUIs), and Xorg7 Libraries

Optional

, libdrm-2.4.129, libxml2-2.15.1, and libspectre

[Note]

Note

There is a circular dependency between cairo and harfbuzz. If cairo is built before harfbuzz, it is necessary to rebuild cairo after harfbuzz in order to build pango.

Installation of Cairo

Prepare Cairo by running the following commands: 

meson setup build --prefix=/usr --buildtype=release
ninja -C build

This package does not have a working test suite.

Now Install, as the root user: 

ninja -C build install

Command Explanations

-D xlib-xcb=enabled: This switch enables several experimental Xlib/XCB functions used by some window managers.

-D gtk_doc=true: Use this parameter if GTK-Doc is installed and you wish to create and install the documentation.
