[Moises <ammoises yahoo com mx>]

Hello to all, My name is Moises.

sorry for my English.

I am working with Ubuntu 7.10 and I installed gtk+ and
gtkglext with Synaptic Package Manager, and I have
next problem I can compile example of gtk+ with:

gcc `pkg-config --cflags --libs gtk+-2.0` main.c -o
main.e

but when I try to compile example share-lists.c of
gtkglext with:

gcc `pkg-config --cflags --libs gtk+-2.0` main.c -o
main.e

But when I try to compile the example of gtkglext
share-lists.c gives me the following error:

get me next errors:
