For running Sogo, you need to have the free OpenGL substitute
Mesa installed as well as
i.e. the OpenGL Utility Toolkit. In the SuSE 7.2 Linux distribution, for
example, just install the packages mesa, mesa3dfx,
mesaglu, mesaglut, and mesasoft from the
x3d series. Apart from that, you also need to have a graphical user
interface installed, of course. You might need additional software, which
is not explicitly listed here.
Copy all files from the bin/linux directory to a directory of your choice, where you want Sogo to be installed. To use the hardware graphics accelaration, the Glide Library must be installed. This is important, since Sogo with software rendering is very slow. Sogo has been tested with the 3Dfx Glide driver for Mesa. In the SuSE 7.2 Linux distribution, this can be found in the package mesa3dfx in the x3d series. Other glide drivers might be necessary. For hardware acceleration Sogo must be run with root privileges. This can be achieved by setting the suid bit and changing the file owner to root:
chmod +s sogo
chown root sogo
If the acceleration still does not work, invoke export MESA_GLX_FX="fullscreen" in the bash before running sogo. Please refer to the documentation README.3DFX in the Mesa documentation directory for details on this.
Finally, you can start Sogo from the directory where you copied the files to. Just invoke the sogo program from the Shell or from a graphical user interface.
Make sure that there is an OpenGL driver
installed on your Windows system. You can check that if you hit the right
mouse button on your desktop and select "Properties" from the pop-up menu.
There should be some OpenGL options in the display settings window. If there
is no OpenGL driver installed on your Windows system, you can get the latest
and fastest driver for your graphics board at
GLSetup (you can use
to get the driver). This is especially important on Windows 95 and Windows
98 boxes, which usually do not come with an OpenGL driver.
Next, you can copy the bin\windows directory to some place of your choice, e.g. C:\Programme\Sogo. Then create a shortcut for SOGO.EXE in your start menu or on the desktop (read the Windows help if you do not know how to do that). To start Sogo, just click on the shortcut.
