I am not sure, but I think this is because of version mismatches between GtkGlExt and other libraries.
You need an older version of pango and gtk+ OR a newer version of GtkGlExt. o
Or just use the pre-compiled version which comes with your operating system.

hi~
I am a student and now I am using the gtkglext in linux (Fedora), and I have some problems. So I Want to
get some help from you, thank you very much ^_^
I download the source code gtkglext-1.0.6, as README tells, I compile and install it.
Here is my command lines and results:
# ./configure --prefix=/usr
...
configuration:
OpenGL CFLAGS:
OpenGL LIBS: -lGLU -lGL
multihead support: yes
debug: minimum
extra defs:
# make
...
# make install
...
Till now,everything seems good (no error is proposed). But when I use the command line "make
examples",there are some link errors:
../gdk/.libs/libgdkglext-x11-1.0.so: undefined reference to `pango_x_font_subfont_xlfd'

When I compile the source code button.c, it's OK. But when I link it, there are errors:
[root localhost examples]# gcc -c button.c `pkg-config --cflags gtkglext-1.0`
[root localhost examples]# gcc -o button button.o -lm `pkg-config --libs gtkglext-1.0`
