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. ----cut here for Makefile ----- FILES = your_app.x SPECIAL_INCLUDES = -I/usr/include/GL SPECIAL_CFLAGS = -g -ansi -pedantic -funroll-loops -ffast-math -DSHM SPECIAL_LIBS = -lglut -lGLU -lGL -lm -L/usr/X11/lib -lXext -lXmu -lXi \ -lX11 -lbsd -g STANDARD_OFILES = $(FILES:.x=.o) %.o: %.c gcc -c $(SPECIAL_CFLAGS) $(SPECIAL_INCLUDES) $< -o $@ all: $(STANDARD_OFILES) gcc -o your_app $(STANDARD_OFILES) $(SPECIAL_LIBS) ----cut here for Makefile----- 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.
