The demo still uses the old GtkGLExt binding, which usually

The newer GLArea is easier to use since it's part of GTK.
As for the linker errors, you'll need to link with the OpenGL
libraries:
"-L-lGL -L-lGLU"
Hey, thanks for your fast answer! I had a lot of other work to
do, so I could only continue working on this project now.
Yeah, that solved my problem :) Now it links. Although if I
execute the program, it complains about the missing GtkGLExt
library, like expected...
Library load failed: libgdkglext-3.0.so.0
So I wanted to install this library from here:
https://projects.gnome.org/gtkglext/download.html
but the ./configure script tells me,
No package 'pangox' found (pangox >= 1.0.0)
I looked at the folder /usr/lib/x86_64-linux-gnu/ and there is a
file called "libpangox-1.0.so.0.0.0". So I don't know, why this
is not working...
Anyway, I want to follow Mikes advice and use GLArea instead, so
if there is not a quick fix available, lets skip the problems
with the GtkGLExt library...
But, sadly enough, I did not get GLArea working, too. The
documentation
https://developer.gnome.org/gtk3/stable/GtkGLArea.html
says, I have to connect my render function to the widget like
this:
g_signal_connect (gl_area, "render", G_CALLBACK (render), NULL);
But, my compiler can't find the g_signal_connect method (and the
GL Methods...):
main.d(22): Error: undefined identifier 'g_signal_connect'
main.d(39): Error: undefined identifier 'glClearColor'
main.d(40): Error: undefined identifier 'glClear'
There might some include files (or import files, as you say in D)
missing, but I could not figure out, where to find them for D...
Could you tell me, where this g_signal_connect method can be
found? And what I have to include for the GL functionality?
Simply "import gtk.GLArea;" does not do the trick...
Btw, is g_signal_connect a GTK method? I intend to use my program
platform independent, so if this is dependent on gnome, it would
not be good.
Or is there any other way to get the GLArea working? I am used to
the Qt Libraries, where you create a QGLWidget and simply
override the init and render functions.
Thanks for reading this far, would be great if we could solve
this problem :D
