Some more information. After I finished lfs I have installed everything in the chapter 24. X Window System Environment, including all dependencies. After that I have installed the following packages in this order:
Code:
PCRE-8.31
D-Bus-1.6.8
GLib-2.34.2
desktop-file-utils-0.21
Cairo-1.12.8
ICU-49.1.2
Harfbuzz-0.9.6
Pango-1.32.2
libjpeg-8d
Imlib2-1.4.5
openbox-3.5.0
LibTIFF-4.0.3
Py2cairo-1.10.0
gobject-introspection-1.34.2
PyGObject-2.28.6
ATK-2.6.0
gdk-pixbuf-2.26.5
hicolor-icon-theme-0.12
libusb-1.0.9
Cups-1.6.1
(GTK+-2.24.13 - not yet installed)
Google showed me
this, so I think it has something to do with gobject-introspection. I guess the problem might be that I installed Pango before gobject-introspection. I'll reinstall Pango and see if it helps.
I'm a bit confused about in which order to install everything. The chapter in the book is not in dependency-order. So I thought I'll start with Openbox, and after that... I'm planlessly installing what I come to think about at the moment...
