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 [email protected] +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 +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.
