Release notes for the OpenGL(R) Sample Implementation (Aug. 4, 2000) Jon Leech, Craig Dunwoody, Dave Shreiner OpenGL Core Engineering SGI INTRODUCTION These notes briefly describe the structure of the Sample Implementation (SI) source tree and how it can be built. These are preliminary, and people who are not highly familiar with building X are likely to have trouble following these instructions. Please bear with us as we move into the open source world. We're undergoing a big transition moving from our internal Perforce-based source code repository to the CVS-based repository on http://oss.sgi.com, and we aren't able to build in the wide variety of environments that open source developers have access to. There will be startup pains as people get started using the code. Feedback on problems (and fixes) to the ogl-sample@oss.sgi.com mailing list will be greatly appreciated, so the build process gets easier for everyone. For the latest list of changes to the SI, please see the file main/doc/release/relnotes. TREE STRUCTURE The source tree containing the Sample Implementation (SI) is structured as follows: doc/man Source and script tools for GL/GLU/GLX manpages doc/release More detailed release notes gfx GL and GLU libraries gfx/lib/glu GLU library gfx/lib/glw GLw Motif widget gfx/lib/opengl GL core rendering library gfx/lib/opengl/defs gfx/lib/opengl/include Internal header files gfx/lib/opengl/generated Generator scripts gfx/lib/opengl/glcore GL core library gfx/include gfx/include/gl GL and GLU headers gfx/include/gl/spec ".spec" files for generating API and protocol wrappers gfx/include/gl/template Generator scripts gfx/include/gl/internal gfx/include/glx GLX headers gfx/lib/glut GLUT library for samples gfx/lib/glfont Simple font library for samples gfx/lib/rgb Simple image library for samples gfx/samples Sample programs (most already open source) glx GLX library glx/include Headers glx/lib Client code glx/server Server code tools Build tools tools/man2html manpage -> HTML converter tools/libspec .spec file tools tools/include GNU make rules/macros tools/gfxinstall Portable install script BUILDING THE SAMPLE IMPLEMENTATION QUICK RECIPE: 1) Follow the 'BUILDING IN THE SI TREE' instructions below to create the generated files. 2) Next, follow the 'BUILDING IN THE X TREE' instructions below to export SI files to the X tree. 3) Finally, follow the instructions in doc/release/build_xfree86 to modify your X tree to link against and intitialize GL, then build the X server. MORE DETAILS: The tree can be used in two ways. First, the SI can be built entirely within its own tree and the resulting libraries copied into an X11R6 tree and used to build a GLX-capable X server. This is how we usually work at SGI; we'll call this the "SI tree" below. The SI tree is heavily based on GNU make. Alternatively, the source tree can be exported into a different structure which fits directly into an X11R6 tree, and is built as part of the X build. This is how the SI is shipped to our licensees; we'll call this "X tree". This uses imake, like everything else in the X11 tree. It's probably going to be easier to build in the X11 tree at first, but moving to the SI tree over time is preferable since mapping changes from files in the X tree to the SI tree is tedious. There are a number of databases and generator scripts used when building within the SI tree. The generated files include GLX protocol encoder and decoder routines for indirect rendering, header files, and some others. When exporting into the X tree, the generated files are included and the generator scripts are not. The generator scripts are a mix of awk and Perl today; we'd like to move completely to Perl in the near future, for better crossplatform support. Unfortunately, the two build processes are somewhat interdependent. To build in the X tree, you must first build (just once) in the SI tree to create the generated files that are part of what's exported. To build in the SI tree and then include the resulting GL/GLX libraries in a new X server, some framework in the X tree is required so it will know to initialize GLX and link against the GL/GLX libraries. Thus the 'QUICK RECIPE' above follows both steps and leaves you with a buildable X tree including GL support. BUILDING IN THE SI TREE To build the SI, you must have also have a X11R6/XFree86 source tree to provide X headers. We currently build against XFree86 3.3.5 on Linux and will upgrade to XFree86 4.0 when it goes public in the near future. The following environment variables are used by the build. All except GLDEBUG are required. GLDEBUG Set GLDEBUG=1 to compile everything with debug flags. GLPRODUCT Set GLPRODUCT=DDX. Controls the type of driver to build. In the future other drivers will use a different GLPRODUCT setting. TOPDIR Set TOPDIR to the path to the root of the SI tree (e.g. this README.1st file should be under $TOPDIR). ROOT Set ROOT to the path to a directory used for installing scripts, headers, and libraries generated by the build. It's almost certainly a bad idea to just set ROOT=/ and install directly into /usr/include, /usr/lib, etc. - we recommend setting $ROOT=${TOPDIR}/root XTOPDIR Set XTOPDIR to the path to the root of your X11R6/XFree86 source tree (e.g. the 'xc' directory should be under $XTOPDIR). This is required to pick up X11 headers used in building GLX. Once these environment variables are set, you can go to $TOPDIR and 'gmake World' (this can take quite awhile and consume a lot of disk space, since a large number of sample programs are built. Later you may wish to just rebuild the client and server libraries). If you're going to export to the X tree, go on to the 'BUILDING IN THE X TREE' instructions in the next section. Otherwise: The result of 'gmake World' should be a tree under $ROOT including these files: $ROOT/usr/include/GL/*.h GL, GLX, and GLU header files $ROOT/usr/lib/libGL.so GL/GLX client library libGLU.so GLU client library libGLw.a Motif GL widget libglfont.a Support libraries for samples libglut.a " librgb.a " libdixGL.a X server GLX library libGLcore.a X server GL library (core renderer) libdixGL.a and libGLcore.a will need to be included in your XFree86 build. The other libraries are client libraries which can be installed in /usr/lib or just used via LD_LIBRARY_PATH. BUILDING IN THE X TREE The export process requires all the generated files, so you'll need to build in the SI tree once (as described above) first. Once we get the website rolling a bit more, we should be able to regularly put up tarballs of the SI files in the X tree structure distribution on a regular basis, instead of requiring you to do this yourself. The next step is to export from the SI tree to the X tree. It's probably best to use an intermediate directory at first, until you're comfortable with the export process - otherwise the chance of scribbling over unexpected parts of the X tree is high. To export: 1) Set the environment variable 'DIST' to the directory to which the files will be exported, e.g. setenv DIST /tmp/dist 2) In $TOPDIR, install the build tools: gmake tools_install 3) Export the files gmake distsi After this completes, the following directories will be created under $DIST: xc/include/GL xc/lib/GL xc/programs/Xserver/GL xc/programs/Xserver/include/GL xc/contrib/GL xc/doc/man/GL xc/doc/hardcopy/GL These can then be overlaid into your X tree by: (cd $DIST && tar cf - xc) | (cd $XTOPDIR && tar xf -) It's also possible to just set DIST=$XTOPDIR if you're confident, and avoid the intermediate step. Finally, once you have the files installed in the X tree, refer to $TOPDIR/doc/release/build_xfree86 for instructions on how to modify the XFree86 build to incorporate the SI.
