3. Install Software

3.1. Install XFree86

Installation of the software packages requires root login, which can be
obtained easily via the superuser/setuser command: su - (see, man su).

If you have a version of XFree86 installed already, you may want to move it
or delete it. However, installing over an existing X is generally OK and
preserves any programs or libraries you might have installed into the X
directories (not that you should really do that):
        cd /usr                                                              
        mv X11R6 X11R6-old                                                   
        cd /etc                                                              
        mv X11 X11-old                                                       
                                                                             
        -- you may have an X directory in /var also                          
        cd /var                                                              
        mv X11R6 X11R6-old                                                   
                                                                             

If these locations are not correct for your distribution of Linux, you will
have to look around your filesystem a bit - try looking in /var

        cd /usr/src                                                          
        mkdir release                                                        
        cd release                                                           
        tar -xvzf X402src-1.tgz                                              
        tar -xvzf X402src-2.tgz                                              
        tar -xvzf X402src-3.tgz                                              
        tar -xvzf doctools-1.2.tar.gz                                        
                                                                             
        -- unpack the man pages (actually, glx pages are already present)    
        cd /usr/src                                                          
        tar -xvzf mangl.tar.Z                                                
        tar -xvzf manglu.tar.Z                                               
                                                                             

A file has to be edited to allow these man pages to compile/install with the
rest of the distribution:
        cd /usr/src/release/xc/doc/man/GL                                    
        Edit the file: Imakefile                                             
                SUBDIRS = glx gl glu                                         
                                                                             

When you unpacked the man*.tar.Z files above, two new directories where
added: gl glu

        cd /usr/src/release                                                  
        cd doctools                                                          
                                                                             
        -- Having this variable set confuses the sgml docs build.            
        -- With it unset, the build uses the proper defaults.                
        unset $SGML_CATALOG_FILES                                            
                                                                             
        make                                                                 
        make install

        -- make symlinks

        ln -s ../X11R6/include/DPS DPS                                       
        ln -s ../X11R6/include/GL GL                                         
        ln -s ../X11R6/include/X11 X11                                       
        ln -s ../X11R6/include/bitmaps bitmaps                               
        cd ..                                                                
        ln -s X11R6 X11                                                      
                                                                             

Add /usr/X11R6/lib to your /etc/ld.so.conf file, then run the command 
ldconfig to update /etc/ld.so.cache so the libraries will be visible.

The GL/GLX/GLU HTML documentation is located at /usr/src/release/xc/doc/
hardcopy/GL. This directory can be copied as follows:
                cd /usr/src/release/xc/doc/hardcopy                          
                cp -r GL /usr/X11R6/lib/X11/doc/html                         
                                                                             
The index.html file in the docs points to manindex5x.html, but the filename
may actually be manindex5.html. Just make a symlink to fix it:
                cd /usr/X11R6/lib/X11/doc/html                               
                ln -s manindex5.html manindex5x.html                         
                                                                             

When X is up and running (later), try using the xman program to see that the
gl,glx,glu and glut man pages are in section 3. If you have KDE2, khelpcenter
allows man-page browsing.
-----------------------------------------------------------------------------

3.2. Install Mesa

Note: This gives you the libGLU* and libglut* files that are missing in 
XFree86. XFree86 only comes with the OpenGL core library, libGL (based on
Mesa). This also installs Mesa's libGL, but we will delete that since it is
to be replaced by the Nvidia libGL.

It's best to uninstall any old Mesa version you may have installed before
installing a new Mesa. Uninstalling software can be a dangerous operation, so
know what you are doing!

To completely uninstall any Mesa libs that may have come with Slackware:
                removepkg mesa                                               
                                                                             
For rpm-based systems (like RedHat and Mandrake), try:
                -- see what will be removed first                            
                rpm -e --test Mesa | less                                    
                -- if ok, proceed                                            
                rpm -e Mesa                                                  
                                                                             
For Debian, you can try:
                apt-get remove Mesa                                          
                                                                             
Procedures vary for other distributions. If there is no clear way to
uninstall an existing Mesa, then at least confirm where it is installed:
normally either under /usr or /usr/local. The example below assumes that Mesa
is installed (or going to get installed) under /usr. Installing over an old
version is probably harmless. Look for /usr/lib/libMesa* or /usr/local/lib/
libMesa* and delete them unless you have programs that need them.

        -- IF you are going to use the project GLUT distribution of GLUT, then  
        -- unpack the Glut-3.7 packages ...                                     
        -- Mesa's compile looks for it                                          
        cd /usr/src                                                             
        tar -xvzf glut-3.7.tar.gz                                               
        tar -xvzf glut_data-3.7.tar.gz                                          
        -- IF you are using this GLUT, use the --with-glut=/usr/src/glut-3.7    
        -- parameter with Mesa's ./configure below in addition to the --prefix  
                                                                                
        cd /usr/src                                                             
        tar -xvzf MesaLib-3.4.tar.gz                                            
        tar -xvzf MesaDemos-3.4.tar.gz                                          
        cd Mesa-3.4                                                             
        ./configure --prefix=/usr                                               
        make                                                                    
        make install                                                            
        ldconfig                                                                
                                                                                

At this point, Mesa installed its own version of the glx.h include files over
the ones that XFree86 installed. This will cause some programs to fail to
compile and is corrected by copying the XFree86 GL include files from the X
source back to your system:
        cp /usr/src/release/xc/include/GL/*.h /usr/X11R6/include/GL          
                                                                             
-----------------------------------------------------------------------------

3.3. Install Nvidia OpenGL drivers

        -- delete the libGL.* files that come with XFree86 / Mesa 3.4 ...

    Tip: If you experience problems starting X, see the files
    TNT_USERS_README and M64_USERS_README. These files explain how to tweak
    the kernel driver. They were written to fix problems with TNT and TNT2
    M64 cards but these tweaks are reported to help the GeForce2 MX also. Try
    bypassing the BIOS as explained in M64_USERS_README.

                Replace 'driver "nv"' with 'driver "nvidia"'                           
                Put "1600x1200" first (or your preferred screen resolution)            
                Copy ttf fonts from Windows into a font directory and add a font path. 
                Use ttmkfdir (check freshmeat.net) to a fonts.dir file.                
                A good place to keep your own fonts is /usr/local/share/fonts ...

        -- You may like to edit /etc/X11/xinit/xinitrc to have run "startkde"          
        -- or "gnome-session" instead of twm.                                          
                                                                                       
        -- Note: /usr/include/GL should be a symlink to /usr/X11R6/include/GL          
                                                                                       

Specifying "nvidia" for the driver in the XF86Config makes that take effect
each time you startx. But the NVdriver kernel driver will have to be loaded
each time your system boots using:
                insmod NVdriver                                              
                                                                             
You can place this command in one of the system startup files, like /etc/rc.d
/rc.modules. But this may not be necessary if the following line is present
in /etc/modules.conf (or conf.modules):
                alias char-major-195 NVdriver                                
                                                                             
If this line is present, NVdriver is loaded automatically when X is started
(autoclean). You can check if its loaded using the command, lsmod.

3.4. Install Qt

        -- for Qt, there is no "make install", just place the source         
        -- where you want it to live:                                        
        cd /usr/local                                                        
        tar -xvzf qt-x11-2.2.4.tar.gz                                        
        ln -s qt-2.2.4 qt                                                    
        cd qt                                                                
                                                                             

Read the INSTALL file about environment variables to setup before you try to
build Qt. You can add the following to /etc/profile:
                QTDIR=/usr/local/qt                                          
                PATH=$PATH:$QTDIR/bin                                        
                MANPATH=$MANPATH:$QTDIR/man                                  
                LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$QTDIR/lib                  
                export QTDIR PATH MANPATH LD_LIBRARY_PATH                    
                                                                             
LD_LIBRARY_PATH is optional if you include an entry in /etc/ld.so.conf for
the library path: /usr/local/qt/lib, then run ldconfig to update /etc/
ld.so.cache.

        -- note: configure has some options you can try, to see them                     
        -- see ./configure --help                                                        
        ./configure                                                                      
                                                                                         
        -- NOTE: when you run make as suggested on the next line, you may                
        -- encounter a make error that halts the build IF you run make                   
        -- from outside X.  The program $QTDIR/bin/uic (the User Interface Compiler)     
        -- may Segmentation Fault when run from a Linux console.  You can run            
        -- "startx" and use the twm (tiny window manager) and xterm (or whatever you     
        -- might have setup for X) to run the rest of the Qt build.  If for some         
        -- reason twm is not even available, then you can run "XFree86 &", use           
        -- "CTRL-ALT-F1" to get to a console, start an xterm as                          
        --  "xterm -display localhost:0.0 &", then switch back to X with "ALT-F7".

    -- Only for old versions of Qt before 2.1.0 or so ...

3.5. Install GLUT 3.7 Distribution (optional)

If you installed the MesaDemos package along with the Mesa 3.4, then you have
already installed GLUT 3.7 since it is included with MesaDemos. However, you
may be interested in installing the GLUT manpages and you can skip right to
the "Install GLUT manual pages", below ...

Installing GLUT is a bit tricky. I'm not too familiar with imake, the program
that it uses to manage the Makefiles, and didn't quite see how to get GLUT to
install to where I wanted it (/usr/lib, but MesaDemos will do this without
any trouble though). It can be done manually anyhow:

        cd /usr/src                                                          
        tar -xvzf glut-3.7.tar.gz                                            
        cd glut-3.7                                                          
                                                                             
        Read the file: README.linux                                          
        cd linux                                                             
        READ the file: README                                                
        cp Glut.cf ..

3.6. Install Java 3D (optional)

If you already have a Java JDK/SDK or JRE, that is, a Java/Software
Development Kit or Java Runtime Environment, installed, then you may have to
take care to uninstall them or leave them alone!

It is recommended that you have the lastest version of Netscape 4.7x, which
at this time of writing, is 4.76, if you plan to install the Java PlugIn for 
netscape. It works, but you may (or may not) experience Segmentation Faults
when leaving a page that contained a Java 3D applet - KDE [http://
www.konqueror.org/] Konqueror 2.1 works well.

Assuming you are logged in as root and have downloaded the Java packages from
blackdown.org into the root home directory, /root, do:

Install the Java 2 SDK (1.2.2) and Java 3D (1.2) extension:
                cd /usr/local                                                
                tar -xvyf ~/j2sdk-1.2.2-FCS-linux-i386-glibc-2.1.3.tar.bz2   
                ln -s jdk1.2.2 jdk                                           
                cd jdk                                                       
                tar -xvyf ~/java3d1_2-FCS-linux-i386-sdk.tar.bz2             
                cd jre/lib/ext                                               
                cp j3d* ..                                                   
                cp vecmath.jar ..                                            
                cd /usr/local                                                
                chown -R root:root jdk1.2.2                                  
                                                                             

Edit /etc/profile, add:
                JAVA_HOME=/usr/local/jdk                                     
                PATH=$PATH:$JAVA_HOME/bin                                    
                export JAVA_HOME PATH                                        
                                                                             
This completes the installation of the Java 2 SDK, which includes the JRE,
and the Java 3D 1.2 extension.

Install the Java PlugIn for netscape:
                -- source profile to set JAVA_HOME and PATH                  
                source /etc/profile                                          
                cd                                                           
                chmod u+x JavaPlugIn-1.2.2-FCS-linux-i386-glibc-2.1.3.run    
                ./JavaPlugIn-1.2.2-FCS-linux-i386-glibc-2.1.3.run            
                -- each user has to run this file to install the plugin      
                -- it is per user, not global                                
                netscape &                                                   
                                                                             
When netscape loads, go to Edit+Preferences->Advanced and Enable Java and
Enable Java Plugin, then exit Netscape.

The next step is to configure the Java PlugIn. It comes with a configuration
applet.
                netscape ~/.netscape/java/ControlPanel.html &                
                -- the Control Panel for JavaPlugIn should load              
                                                                             
Again, netscape will load. Click the "Advanced" tab, select "Other ..." and
type for Path:
                /usr/local/jdk1.2.2/jre                                      
                                                                             
Then click "Apply" and exit Netscape. By changing this, it tells the Plugin
to use the system Java Runtime Environment instead of the JRE it installed
under ~/.netscape. The system JRE is where the Java 3D API extension is
installed.

Test Java 3D demos:
                cd $JAVA_HOME/demo/java3d/GearTest                           
                java GearBox &                                               
                -- runs as normal java application                           
                netscape GearBox_plugin.html &                               
                -- runs in netscape as an applet                             
                                                                             

If you experience trouble with Java, you can try deleting ~/.java and related
files in your home directory, then try again. These files left over from a
prior Java installation can cause problems.

If all works well, you should have a complete Java Developement and Runtime
Environment for both normal apps and high-performance 3D apps. See [http://
java.sun.com/] http://java.sun.com/ for further information about Java and
the Java 3D extension.
