the canonical system name and include the corresponding Makefile snippet from config/. config.guess has been written with portability in mind, so it should work properly on all supported systems. Should its licence (GPL) become a problem, it can be replaced with a simpler script that supports only the systems we know something about. Adding support for a new system is just a matter of running config/config.guess and writing the matching config/Makefile.$system file. git-svn-id: https://glew.svn.sourceforge.net/svnroot/glew/trunk/glew@315 783a27ee-832a-0410-bc00-9f386506c6dd

The goal of the OpenGL Extension Wrangler Library (GLEW) is to assist
|
|
C/C++ OpenGL developers with two tedious tasks: initializing and using
|
|
extensions and writing portable applications. GLEW provides an
|
|
efficient run-time mechanism to determine whether a certain extension
|
|
is supported by the driver or not. OpenGL core and extension
|
|
functionality is exposed via a single header file. GLEW currently
|
|
supports a variety of platforms and operating systems, including
|
|
Windows, Linux, Darwin, Irix, and Solaris.

|
|
<p>
|
|
|
|
There are two ways to build your project with GLEW.
|
|
<p>
|
|
|
|
<h3>Including the source files / project file</h3>
|
|
<p>
|
|
|
|
The simpler but less flexible way is to include <tt>glew.h</tt> and
|
|
<tt>glew.c</tt> into your project and define the <tt>GLEW_STATIC</tt>
|
|
preprocessor constant for the static library or executable you are
|
|
building together with GLEW (Windows only). You also need to replace
|
|
<tt><GL/gl.h></tt> and <tt><GL/glu.h></tt> with
|
|
<tt><glew.h></tt> in your code and set the appropriate include
|
|
flag (<tt>-I</tt>) to tell the compiler where to look for it. For
|
|
example:
|
|
|
|
<blockquote><pre>#include <glew.h>
|
|
#include <GL/glut.h>
|
|
<gl, glu, and glut functionality is available here>
|
|
</pre></blockquote>
|
|
|
|
Depending on where you put <tt>glew.h</tt> you may also need to change
|
|
the include directives in <tt>glew.c</tt>. Note that if you are using
|
|
GLEW together with GLUT, you have to include <tt>glew.h</tt> first.
|
|
In addition, <tt>glew.h</tt> includes <tt>glu.h</tt>, so you don't
|
|
need to include it separately.
|
|
|
|
<p>
|
|
On Windows you also have the option of adding the supplied project
|
|
file <tt>glew_static.dsp</tt> to your workspace (solution) and compile
|
|
it together with your other projects. In this case you need to change
|
|
the <tt>GLEW_BUILD</tt> preprocessor constant to <tt>GLEW_STATIC</tt>,
|
|
otherwise you get build errors. <b>Note that GLEW does not use the C
|
|
runtime library, so it does not matter which version (single-threaded,
|
|
multi-threaded or multi-threaded DLL) it is linked with (without
|
|
debugging information). It is, however, always a good idea to compile all
|
|
your projects including GLEW with the same C runtime settings.</b>
|
|
|
|
<p>
|
|
|
|
<h3>Using GLEW as a shared library</h3>
|
|
<p>
|
|
|
|
Alternatively, you can use the provided project files / makefile to
|
|
build a separate shared library you can link your projects with later.
|
|
In this case the best practice is to install <tt>glew.h</tt>,
|
|
<tt>glew32.lib</tt>, and <tt>glew32.dll</tt> / <tt>libGLEW.so</tt> to
|
|
where the OpenGL equivalents <tt>gl.h</tt>, <tt>opengl32.lib</tt>, and
|
|
<tt>opengl32.dll</tt> / <tt>libGL.so</tt> are located. Note that you
|
|
need administrative privileges to do this. If you do not have
|
|
administrator access and your system administrator will not do it for
|
|
you, you can install GLEW into your own lib and include subdirectories
|
|
and tell the compiler where to find it. Then you can just replace
|
|
<tt><GL/gl.h></tt> with <tt><GL/glew.h></tt> in your
|
|
program:
|
|
|
|
<blockquote><pre>#include <GL/glew.h>
|
|
#include <GL/glut.h>
|
|
<gl, glu, and glut functionality is available here>
|
|
</pre></blockquote>
|
|
|
|
or:
|
|
|
|
<blockquote><pre>#include <GL/glew.h>
|
|
<gl and glu functionality is available here>
|
|
</pre></blockquote>
|
|
|
|
<p>
|
|
Don't forget to link your project with <tt>glew32.lib</tt>,
|
|
<tt>glu32.lib</tt>, and <tt>opengl32.lib</tt> on Windows and
|
|
<tt>libGLEW.so</tt>, <tt>libGLU.so</tt>, and <tt>libGL.so</tt> on
|
|
Linux and IRIX (<tt>-lGLEW -lGLU -lGL</tt>).
|
|
|
|
<p>
|
|
It is important to keep in mind that <tt>glew.h</tt> includes neither
|
|
<tt>windows.h</tt> nor <tt>gl.h</tt>. Also, GLEW will warn you by
|
|
issuing a preprocessor error in case you have included <tt>gl.h</tt>,
|
|
<tt>glext.h</tt>, or <tt>glATI.h</tt> before <tt>glew.h</tt>.

|
To install the shared library version of GLEW you need to copy the
|
|
headers and libraries into their destination directories. On Windows
|
|
this boils down to copying (no, we will not write a Windows installer
|
|
for you).

|
|
|
|
<p>
|
|
On Linux and IRIX, typing <tt>"make install"</tt> will attempt to install GLEW

customize the installation target via the <tt>GLEW_DEST</tt>

<h3>Initializing GLEW</h3>
|
|
<p>
|
|
|
|
First you need to create a valid OpenGL rendering context and call
|
|
<tt>glewInit()</tt> to initialize the extension entry points. If
|
|
<tt>glewInit()</tt> returns <tt>GLEW_OK</tt>, the initialization
|
|
succeeded and you can use the available extensions as well as core
|
|
OpenGL functionality. For example:
|
|
|
|
<blockquote><pre>#include <GL/glew.h>
|
|
#include <GL/glut.h>
|
|
...
|
|
glutInit(&argc, argv);
|
|
glutCreateWindow("GLEW Test");
|
|
GLenum err = glewInit();
|
|
if (GLEW_OK != err)
|
|
{
|
|
/* problem: glewInit failed, something is seriously wrong */
|
|
fprintf(stderr, "Error: %s\n", glewGetErrorString(err));
|
|
...
|
|
}
|
|
fprintf(stdout, "Status: Using GLEW %s\n", glewGetString(GLEW_VERSION));
|
|
</pre></blockquote>
|
|
|
|
<p>
|
|
|
|
<h3>Querying the available OpenGL extensions</h3>
|
|
<p>
|
|
|
|
Starting from GLEW 1.1.0, you can find out if a particular extension
|
|
is available on your platform by querying globally defined variables
|
|
of the form <tt>GLEW_{extension_name}</tt>:
|
|
|
|
<blockquote><pre>if (GLEW_ARB_vertex_program)
|
|
{
|
|
/* it is safe to use the ARB_vertex_program extension here */
|
|
glGenProgramsARB(...);
|
|
}
|
|
</pre></blockquote>
|
|
|
|
<b>In GLEW 1.0.x, a global structure was used for this task. To ensure
|
|
binary compatibility between releases, the struct was replaced with a
|
|
set of variables.</b>
|
|
|
|
<p>
|
|
|
|
You can also check for core OpenGL functionality. For example, to
|
|
see if OpenGL 1.3 is supported:
|
|
|
|
<blockquote><pre>if (GLEW_VERSION_1_3)
|
|
{
|
|
/* Yay! OpenGL 1.3 is supported! */
|
|
}
|
|
</pre></blockquote>
|
|
|
|
In general, you can check if <tt>GLEW_{extension_name}</tt> or
|
|
<tt>GLEW_VERSION_{version}</tt> is set or not.
|
|
|
|
<p>
|
|
|
|
For extensions <tt>glewGetExtension</tt> provides a slower alternative:
|
|
|
|
<blockquote><pre>if (GL_TRUE == glewGetExtension("GL_ARB_fragment_program"))
|
|
{
|
|
/* Looks like ARB_fragment_program is supported. */
|
|
}
|
|
</pre></blockquote>
|
|
|
|
|
|
<p>
|
|
|
|
<h3>Experimental drivers</h3>
|
|
<p>
|
|
|
|
GLEW works by querying the supported extensions from the graphics
|
|
driver. Experimental drivers, however, might not report every
|
|
available extension through the standard mechanism, in which case GLEW
|
|
will report it unsupported. To circumvent this situation, the
|
|
<tt>glewExperimental</tt> global switch can be turned on by setting it
|
|
to <tt>GL_TRUE</tt> before calling <tt>glewInit()</tt>. This makes
|
|
sure that all extensions with valid entry points will be exposed.
|
|
|
|
<p>
|
|
|
|
<h3>Platform specific extensions</h3>
|
|
<p>
|
|
|
|
Platform specific extensions are separated into two header files:
|
|
<tt>wglew.h</tt> and <tt>glxew.h</tt>, which define the available
|
|
<tt>WGL</tt> and <tt>GLX</tt> extensions. To determine if a certain
|
|
extension is supported, query <tt>WGLEW_{extension name}</tt> or
|
|
<tt>GLXEW_{extension_name}</tt>. For example:
|
|
|
|
<blockquote><pre>#include <GL/wglew.h>
|
|
|
|
if (WGLEW_ARB_pbuffer)
|
|
{
|
|
/* OK, we can use pbuffers */
|
|
}
|
|
else
|
|
{
|
|
/* Sorry, pbuffers will not work on this platform */
|
|
}
|
|
</pre></blockquote>

|
GLEW provides two command line tools: one for creating a list of
|
|
available extensions and visuals; and another for verifying extension
|
|
entry points.
|
|
|
|
<p>
|
|
|
|
<h3>visualinfo: extensions and visuals</h3>
|
|
<p>
|
|
|
|
<tt>visualinfo</tt> is an extended version of <tt>glxinfo</tt>. On
|
|
Windows, by default it creates a file called <tt>visualinfo.txt</tt>
|
|
that contains a list of available OpenGL, WGL, and GLU extensions as
|
|
well as a table of visuals aka. pixel formats. Pbuffer and multiple
|
|
output capable visuals are also included. For additional usage
|
|
information, type <tt>visualinfo -h</tt>.
|
|
|
|
<p>
|
|
|
|
<h3>glewinfo: extension verification utility</h3>
|
|
<p>
|
|
|
|
<tt>glewinfo</tt> allows you to verify the entry points for the
|
|
extensions supported on your platform. It uses GLEW to find out which
|
|
extensions and entry points are available. On Windows it reports the
|
|
results to a text file called <tt>glewinfo.txt</tt>, on Unix it prints
|
|
them to <tt>stdout</tt>. <p>
|
|
|
|
Windows Usage: <blockquote><pre>glewinfo [-pf <id>]</pre></blockquote>
|
|
|
|
where <tt><id></tt> is the pixelformat id for which the
|
|
capabilities are displayed.
|
|
|
|
<p>
|
|
Unix Usage:
|
|
<blockquote><pre>glewinfo [-display <dpy>] [-visual <id>]</pre></blockquote>
|
|
|
|
where <tt><dpy></tt> is the X11 display and <tt><id></tt> is
|
|
the visual id for which the capabilities are displayed.

|
|
<p>
|
|
|
|
Starting with release 1.1.0, the source code and parts of the
|
|
documentation are automatically generated from the extension
|
|
specifications via a two-step process. In the first step,
|
|
specification files from the OpenGL registry are parsed and 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, 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>
|
|
|
|
To avoid name clashes when linking with libraries that include the
|
|
same symbol, 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>. Note that the separate namespace doesn't
|
|
effect token and function pointer definitions.

|
|
<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:
|
|
|
|
<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>

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>Replace the global <tt>glewInit()</tt> call with
|
|
<tt>glewContextInit(glewGetContext())</tt>. Note, that the
|
|
<tt>GLEWContext</tt> pointer returned by <tt>glewGetContext()</tt> has
|
|
to reside in global or thread-local memory. Also, remember to call
|
|
<tt>glewContextInit</tt> after creating the <tt>GLEWContext</tt> object
|
|
in each rendering context.

|
|
<p>Note that according to <a
|
|
href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/opengl/ntopnglr_6yer.asp">WGL
|
|
documentation</a>, you have to initialize the entry points for every
|
|
rendering context you create 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). <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 (and why would anyone want to use
|
|
the software renderer when hardware acceleration is available?). 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>

GLEW requires GLX 1.2 to assure compatibility with GLUT. Also,
|
|
the SGI GLX video extensions are currently not supported.

GLEW was developed by Milan Ikits and Marcelo Magallon. They also
|
|
perform occasional maintainance to make sure that GLEW stays in mint
|
|
condition. Aaron Lefohn, Joe Kniss, and Chris Wyman were the first
|
|
users and also assisted with the design and debugging process. The
|
|
acronym GLEW originates from Aaron Lefohn. Pasi Kärkkäinen
|
|
identified and fixed several problems with GLX and SDL. Nate Robins
|
|
created the <tt>wglinfo</tt> utility, to which modifications were
|
|
added by Michael Wimmer.
