Mesa 3.0 for LynxOS builds in the following way:
|
||
|
|
|
||
|
|
make lynxos
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
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.
