In the first step, -specification files from the OpenGL registry are downloaded and -parsed. Skeleton descriptors are created for each extension. These -descriptors contain all necessary information for creating the source -code and documentation in a simple and compact format, including the -name of the extension, url link to the specification, tokens, function -declarations, typedefs and struct definitions. In the second step, -the header files as well as the library and glewinfo source are -generated from the descriptor files. The code generation scripts are -located in the <tt>auto</tt> subdirectory. -</p> - -<p> -The code generation scripts require GNU make, wget, and perl. On -Windows, the simplest way to get access to these tools is to install -<a href="http://www.cygwin.com/">Cygwin</a>, but make sure that the -root directory is mounted in binary mode.

This is useful when you do not need all the -extensions and would like to reduce the size of the source files. -Type <tt>make clean; make custom</tt> in the <tt>auto</tt> directory -to rerun the scripts with the custom list of extensions. -</p> - -<p> -For example, the following is the list of extensions needed to get GLEW and the -utilities to compile. -</p> - -<p class="pre"> -WGL_ARB_extensions_string<br> -WGL_ARB_multisample<br> -WGL_ARB_pixel_format<br> -WGL_ARB_pbuffer<br> -WGL_EXT_extensions_string<br> -WGL_ATI_pixel_format_float<br> -WGL_NV_float_buffer<br> -</p> - -<h2>Multiple Rendering Contexts (GLEW MX)</h2> - -<p>Starting with release 1.2.0, thread-safe support for multiple -rendering contexts, possibly with different capabilities, is -available. Since this is not required by most users, it is not added -to the binary releases to maintain compatibility between different -versions. To include multi-context support, you have to do the -following:</p> -<ol> -<li>Compile and use GLEW with the <tt>GLEW_MX</tt> preprocessor token -defined.</li> -<li>For each rendering context, create a <tt>GLEWContext</tt> object -that will be available as long as the rendering context exists.</li> -<li>Define a macro or function called <tt>glewGetContext()</tt> that -returns a pointer to the <tt>GLEWContext</tt> object associated with -the rendering context from which OpenGL/WGL/GLX calls are issued. This -dispatch mechanism is primitive, but generic. -<li>Make sure that you call <tt>glewInit()</tt> after creating the -<tt>GLEWContext</tt> object in each rendering context. Note, that the -<tt>GLEWContext</tt> pointer returned by <tt>glewGetContext()</tt> has -to reside in global or thread-local memory. -</ol> - -<p>Note that according to the <a -href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/opengl/ntopnglr_6yer.asp">MSDN -WGL documentation</a>, you have to initialize the entry points for -every rendering context that use pixel formats with different -capabilities For example, the pixel formats provided by the generic -software OpenGL implementation by Microsoft vs. the hardware -accelerated pixel formats have different capabilities. <b>GLEW by -default ignores this requirement, and does not define per-context -entry points (you can however do this using the steps described -above).</b> Assuming a global namespace for the entry points works in -most situations, because typically all hardware accelerated pixel -formats provide the same entry points and capabilities. This means -that unless you use the multi-context version of GLEW, you need to -call <tt>glewInit()</tt> only once in your program, or more precisely, -once per process.</p> - -<h2>Separate Namespace</h2> - -<p> -To avoid name clashes when linking with libraries that include the -same symbols, extension entry points are declared in a separate -namespace (release 1.1.0 and up). This is achieved by aliasing OpenGL -function names to their GLEW equivalents. For instance, -<tt>glFancyFunction</tt> is simply an alias to -<tt>glewFancyFunction</tt>. The separate namespace does not effect -token and function pointer definitions. -</p> - -<h2>Known Issues</h2> - -<p> -GLEW requires GLX 1.2 for compatibility with GLUT. -</p> - -<!-- begin footer.html --> -</td></tr></table></body> -<!-- end footer.html --> - |
