Cairo：

是 GTK的依赖源，选择版本、是否正确安装，将直接决定了GTK能否顺利安装或者安装完能否正常使用（即GTK使用时编译不会报错）

Cairo-1.12.16 下载网址:

http://www.linuxfromscratch.org/blfs/view/svn/x/cairo.html

软件包配置指令：

    CFLAGS="$CFLAGS -ffat-lto-objects" ./configure  --prefix=/usr --disable-static

指令注释：

CFLAGS="$CFLAGS -ffat-lto-objects": Fixes building with GCC 4.9.

--disable-static: This switch prevents installation of static versions of the libraries.

--enable-xlib-xcb: This switch enables experimental Xlib/XCB functions used by some window managers.

--enable-gl: This switch enablesCairo's experimentalOpenGL surface which is required forWayland compositor and some other packages that are not part of BLFS.

--enable-tee: This switch enables experimental tee surface backend which is required if using system-installedCairo with Mozilla applications.

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

重要说明：

编译时出现各种缺少那是比较正常的事情，请根据报错依次解决吧;

编译请务必加上：--disable-static 此条命令参数可以预防安装静态版本的库, 要不可能GTK调用后，编译报错（诸如cairo-XXX有关的函数、定义之类没找到）。
