I have installed Gtk binding for Lua
liblua5.1-gtk-dev
liblua5.1-gtk-0
from Lenny DVDs. I also have Lua interpreter and dev libraries
lua5.1
liblua5.1-0
liblua5.1-0-dev

When I try to run example program this is the error:

$ /usr/share/doc/liblua5.1-gtk-dev/examples/window.lua
[gtk] Can't load dynamic library /usr/lib/libgtk-x11-2.0.so
[gtk] Can't load dynamic library /usr/lib/libatk-1.0.so
[gtk] Can't load dynamic library /usr/lib/libgtkhtml-2.so
[gtk] symbol g_type_fundamental not found in dynamic library.
[gtk] symbol g_slice_set_config not found in dynamic library.
<... snipped many similar lines ...>
[gtk] symbol g_assertion_message not found in dynamic library.
[gtk] symbol gtk_tree_model_get_value not found in dynamic library.
[gtk] ERROR - an unavailable function

It seems that some libs can not be found but they are installed too:

$ dlocate libgtk-x11-2.0.so
libgtk2.0-0: /usr/lib/libgtk-x11-2.0.so.0.1200.12
libgtk2.0-0: /usr/lib/libgtk-x11-2.0.so.0

$ dlocate libatk-1.0.so
libatk1.0-0: /usr/lib/libatk-1.0.so.0.2209.1
libatk1.0-0: /usr/lib/libatk-1.0.so.0

$ dlocate libgtkhtml-2.so
libgtkhtml2-0: /usr/lib/libgtkhtml-2.so.0.0.0
libgtkhtml2-0: /usr/lib/libgtkhtml-2.so.0

I can not think of anything why is example program not able
to run. Do I need to install something else?

I find it funny that liblua5.1-gtk-0 package does not depend
on any of the gtk or lua packages. It only recommends
libgtkhtml2-0 and liblua5.1-socket2

As far as I can tell none of the package liblua5.1-* apart of liblua5.1-dev
actually depend on liblua5.1 package. Isn't this an packaging error?

I have no experience with lua, but your error messages seem to tell me
that the libraries cannot be loaded because they have undefined symbols
that the linker cannot find anywhere else.

You are missing some pretty elementary things, such as
g_type_fundamental, which should be provided by a library from
libglib2.0-0. This package is a dependency of libgtkhtml2-0, so it
should be present on your system. Please post the output of:

dpkg -l libgtkhtml2-0 | awk '/^[^D|+]/{print $1,$2,$3}'
nm -D /usr/lib/libgobject-2.0.so.0 | grep g_type_fundamental
ldconfig -pNX | grep libgobject-2.0.so.0

Here are outputs:

$ dpkg -l libgtkhtml2-0 | awk '/^[^D|+]/{print $1,$2,$3}'
ii libgtkhtml2-0 2.11.1-2

$ nm -D /usr/lib/libgobject-2.0.so.0 | grep g_type_fundamental
00021c90 T g_type_fundamental
000230d0 T g_type_fundamental_next

$ /sbin/ldconfig -pNX | grep libgobject-2.0.so.0
libgobject-2.0.so.0 (libc6) => /usr/lib/libgobject-2.0.so.0

Does anybody successfuly use liblua5.1-gtk-0 ?
