Have you taken a look at the sample programs?

Yep, I am going through them, beginning with "starter". Unfortunately, I can't compile them because iCompile can't find X11/Xlib.h or X11/Xutil.h

I built G3D twice. The first time, I got several warnings but things seemed fine. The second time, buildg3d said:

Header not found: 'X11/Xlib.h'.

Header not found: 'X11/Xutil.h'.

In file included from /Users/cjcurrie/Desktop/G3D-9.00-b03-osx/G3D/G3D.lib/source/GImage.cpp:23:

../png.lib/include/png.h:2:2: error: #error "On OS X, G3D is supposed to use the system version of libpng"

Now I'm sure I have those X11 libs on my computer. A quick search showed them to be in my Tk.framework library.

I there any way to tell if the static and dynamic libraries inside G3D-9.00-b03-osx/lib have been built correctly? I put them into /usr/lib, then put the G3D and GlG3D header files into /usr/include. Lastly, I put G3D/data into /usr/local/include.

I think I'm still missing a step....

Is there a particular reason you are using the beta 3 release instead of beta 4?  The imaging code has been replaced.

For X11 headers/libraries, they don't belong to Tk, that is probably a separate install just for the Tk framework.

What version of OS X are you running?

On the G3D project page (http://sourceforge.net/projects/g3d/files/), the most recent version listed for download is beta3. To quote:

Looking for the latest version? Download G3D-9.00-b03-osx.zip (1.2 GB)

I may not have X11 headers in my /usr directory, then, since those Tk framework references were the only ones I could find. I'm running Mountain Lion, OSX 10.8.

On this page, I found the following information from Apple:

X11 is not included with Mountain Lion, but X11 server and client libraries for OS X Mountain Lion are available from the XQuartz project: http://xquartz.macosforge.org. You should use XQuartz version 2.7.2 or later.

I guess that explains it. Going to download and try again.

Thanks, I just fixed that. SourceForge does that automatically and it
is annoying. http://g3d.sf.net has the authoritative links.
