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. + +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.
