1 2 Mesa 3.0 for LynxOS builds in the following way: 3 4 make lynxos 5 6 This will build all the libraries and demo applications. You should have 7 around 400 megabytes free for everything since everything is done with 8 static 9 libraries. 10 11 Before using this make file however, you should perform the following 12 actions: 13 0) cd to the Mesa-3.0 directory 14 1) Copy the GL directory under the include directory to /usr/include. 15 2) Copy the files in the lib directory to /lib. 16 3) Make links so that the Mesa libraries look like ordinary OpenGL 17 libraries 18 in /lib. This is important for compatibility with other OpenGL apps. This 19 is done as follows: 20 21 cd /lib 22 ln -s libMesaGL.a libGL.a 23 ln -s libMesaGLU.a libGLU.a 24 25 Mesa 3.0 includes the GLUT (GL Utility Toolkit) by default. 26 The demo applications are done using this toolkit. 27 28 Mesa makefiles for building their apps could be used as well, but the 29 following one is much more concise. Note that the order of the X libraries 30 is important to the linker so that all symbols get resolved correctly. 31 Changing the order may result in having to list a library twice to make 32 sure all linkages are made correctly. 33 34 ----cut here for Makefile ----- 35 36 FILES = your_app.x 37 38 SPECIAL_INCLUDES = -I/usr/include/GL 39 40 SPECIAL_CFLAGS = -g -ansi -pedantic -funroll-loops -ffast-math -DSHM 41 42 SPECIAL_LIBS = -lglut -lGLU -lGL -lm -L/usr/X11/lib -lXext -lXmu -lXi \ 43 -lX11 -lbsd -g 44 45 STANDARD_OFILES = $(FILES:.x=.o) 46 47 %.o: %.c 48 gcc -c $(SPECIAL_CFLAGS) $(SPECIAL_INCLUDES) $< -o $@ 49 50 all: $(STANDARD_OFILES) 51 gcc -o your_app $(STANDARD_OFILES) $(SPECIAL_LIBS) 52 53 54 ----cut here for Makefile----- 55 56 I have tested Mesa under LynxOS 3.0 and 3.01. It should build fine under 57 other 58 versions as well. Note, however, that LynxOS versions prior to 3.0 are not 59 binary compatible, so you will have to rebuild from source. 60 61 62 Vik Sohal 63 vik (a] lynx.com 64 January 13, 1999 65
