-LynxOS Notes
-------------
+Mesa 3.0 for LynxOS builds in the following way:
 
-The LynxOS make instructions are really a copy of the Linux make with
-the addition of a -lbsd flag for the networking. Everything else seems
-to work fine. Just go to the root directory and type "make lynxos" and 
-the whole mess builds and works without any problems. 
+make lynxos
 
-There is an important note though: Since we don't have shared C libraries yet, 
-this distribution of Mesa becomes quite fat. Around 7 megs of source becomes
-145 Megs of executable. Most of this is in the demo code, but you should 
-be aware of the total disk space being used. When we add shared C libraries, I
-will attempt to build this distribution with shared libraries to conserve 
-space.
+This will build all the libraries and demo applications. You should have 
+around 400 megabytes free for everything since everything is done with 
+static
+libraries.
 
-This build was done under LynxOS 2.5G (an internal release). It should build 
-under 2.4 and 2.5 final. If you have problems, please email me at vik@lynx.com
+Before using this make file however, you should perform the following 
+actions:
+0) cd to the Mesa-3.0 directory
+1) Copy the GL directory under the include directory to /usr/include.
+2) Copy the files in the lib directory to /lib.
+3) Make links so that the Mesa libraries look like ordinary OpenGL 
+libraries
+in /lib. This is important for compatibility with other OpenGL apps. This
+is done as follows:
 
-Vik Sohal
-vik@lynx.com
+cd /lib
+ln -s libMesaGL.a libGL.a
+ln -s libMesaGLU.a libGLU.a
+
+Mesa 3.0 includes the GLUT (GL Utility Toolkit) by default.
+The demo applications are done using this toolkit.
+
+Mesa makefiles for building their apps could be used as well, but the
+following one is much more concise. Note that the order of the X libraries
+is important to the linker so that all symbols get resolved correctly.
+Changing the order may result in having to list a library twice to make
+sure all linkages are made correctly.

+I have tested Mesa under LynxOS 3.0 and 3.01. It should build fine under 
+other
+versions as well. Note, however, that LynxOS versions prior to 3.0 are not
+binary compatible, so you will have to rebuild from source.
