Open Inventor with Gtk+

[Ang Bodhi <angbodhi@xxxxxxxxxxxxxx>]

Hi Inventors,

I'm porting Open Inventor's libInventorXt library to Gtk+.
The new library libInventorGtk is now able to compile and run
with most of the sample and demo applications.

You can get more information and the source from
http://www.geocities.com/angbodhi/download/

The steps to build everything:

1. Build and install the required libraries.
    glib-1.2.8.tgz
    gtk+-1.2.8.tgz
    libgtkgl-1.2.2.tgz

2. Apply a patch to add SoGdkWindowElement to libInventor.so
    $ cd $IVROOT
    $ patch -p1 <lib.patch

3. Build libInventorGtk.so
    $ cd $IV_ROOT
    $ tar zxvf libSoGtk-0.7.0.tgz
    $ cd libSoGtk
    $ make

4. Build tools, samples and demonstration applications
    $ cd $IV_ROOT
    $ tar zxvf gapps-0.7.0.tgz
    $ cd gapps
    $ make

Cheers,
