<h1>The OpenGL Extension Wrangler Library</h1>
|
||||||
|
|
||||||
|
<h2>Automatic Code Generation</h2>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Starting from release 1.1.0, the source code and parts of the
|
||||||
|
documentation are automatically generated from the extension
|
||||||
|
specifications in a two-step process. 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. The makefile in the
|
||||||
|
<tt>auto</tt> directory provides the following build targets:
|
||||||
|

|
||||||

||||||

<h3>Adding a New Extension</h3>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
To add a new extension, create a descriptor file for the extension in
|
||||||
|
<tt>auto/core</tt> and rerun the code generation scripts by typing
|
||||||
|
<tt>make clean; make</tt> in the <tt>auto</tt> directory.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
The format of the descriptor file is given below. Items in
|
||||||
|
brackets are optional.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
<Extension Name><br>
|
||||||
|
[<URL of Specification File>]<br>
|
||||||
|
[<Token Name> <Token Value>]<br>
|
||||||
|
[<Token Name> <Token Value>]<br>
|
||||||
|
...<br>
|
||||||
|
[<Typedef>]<br>
|
||||||
|
[<Typedef>]<br>
|
||||||
|
...<br>
|
||||||
|
[<Function Signature>]<br>
|
||||||
|
[<Function Signature>]<br>
|
||||||
|
...<br>
|
||||||
|
<!-- [<Function Definition>]<br>
|
||||||
|
[<Function Definition>]<br>
|
||||||
|
...<br> -->
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<!--
|
||||||
|
<p>
|
||||||
|
Note that <tt>Function Definitions</tt> are copied to the header files
|
||||||
|
without changes and have to be terminated with a semicolon. In
|
||||||
|
contrast, <tt>Tokens</tt>, <tt>Function signatures</tt>, and
|
||||||
|
<tt>Typedefs</tt> should not be terminated with a semicolon.
|
||||||
|
</p>
|
||||||
|
-->
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Take a look at one of the files in <tt>auto/core</tt> for an
|
||||||
|
example. Note that typedefs and function signatures should not be
|
||||||
|
terminated with a semicolon.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h3>Custom Code Generation</h3>
|
||||||
|
<p>
|
||||||
|
Starting from GLEW 1.3.0, it is possible to control which extensions
|
||||||
|
to include in the libarary by specifying a list in
|
||||||
|
<tt>auto/custom.txt</tt>. 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>
|
||||||
|

<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.

<h1>The OpenGL Extension Wrangler Library</h1>
|
||||||
|
|
||||||
|
<h2>Initializing GLEW</h2>
|
||||||
|
<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:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
#include <GL/glew.h><br>
|
||||||
|
#include <GL/glut.h><br>
|
||||||
|
...<br>
|
||||||
|
glutInit(&argc, argv);<br>
|
||||||
|
glutCreateWindow("GLEW Test");<br>
|
||||||
|
GLenum err = glewInit();<br>
|
||||||
|
if (GLEW_OK != err)<br>
|
||||||
|
{<br>
|
||||||
|
/* Problem: glewInit failed, something is seriously wrong. */<br>
|
||||||
|
fprintf(stderr, "Error: %s\n", glewGetErrorString(err));<br>
|
||||||
|
...<br>
|
||||||
|
}<br>
|
||||||
|
fprintf(stdout, "Status: Using GLEW %s\n", glewGetString(GLEW_VERSION));<br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>Checking for Extensions</h2>
|
||||||
|
|
||||||
|
<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>:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
if (GLEW_ARB_vertex_program)<br>
|
||||||
|
{<br>
|
||||||
|
/* It is safe to use the ARB_vertex_program extension here. */<br>
|
||||||
|
glGenProgramsARB(...);<br>
|
||||||
|
}<br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
<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>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
You can also check for core OpenGL functionality. For example, to
|
||||||
|
see if OpenGL 1.3 is supported, do the following:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
if (GLEW_VERSION_1_3)<br>
|
||||||
|
{<br>
|
||||||
|
/* Yay! OpenGL 1.3 is supported! */<br>
|
||||||
|
}<br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
In general, you can check if <tt>GLEW_{extension_name}</tt> or
|
||||||
|
<tt>GLEW_VERSION_{version}</tt> is true or false.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
It is also possible to perform extension checks from string
|
||||||
|
input. Starting from the 1.3.0 release, use <tt>glewIsSupported</tt>
|
||||||
|
to check if the required core or extension functionality is
|
||||||
|
available:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
if (glewIsSupported("GL_VERSION_1_4 GL_ARB_point_sprite"))<br>
|
||||||
|
{<br>
|
||||||
|
/* Great, we have OpenGL 1.4 + point sprites. */<br>
|
||||||
|
}<br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
For extensions only, <tt>glewGetExtension</tt> provides a slower alternative
|
||||||
|
(GLEW 1.0.x-1.2.x). <b>Note that in the 1.3.0 release </b>
|
||||||
|
<tt>glewGetExtension</tt> <b>was replaced with </b>
|
||||||
|
<tt>glewIsSupported</tt>.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
if (glewGetExtension("GL_ARB_fragment_program"))<br>
|
||||||
|
{<br>
|
||||||
|
/* Looks like ARB_fragment_program is supported. */<br>
|
||||||
|
}<br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>Experimental Drivers</h2>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
GLEW obtains information on the supported extensions from the graphics
|
||||||
|
driver. Experimental or pre-release 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>, which ensures that all extensions with valid
|
||||||
|
entry points will be exposed.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>Platform Specific Extensions</h2>
|
||||||
|
|
||||||
|
<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:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
#include <GL/wglew.h><br>
|
||||||
|
<br>
|
||||||
|
if (WGLEW_ARB_pbuffer)<br>
|
||||||
|
{<br>
|
||||||
|
/* OK, we can use pbuffers. */<br>
|
||||||
|
}<br>
|
||||||
|
else<br>
|
||||||
|
{<br>
|
||||||
|
/* Sorry, pbuffers will not work on this platform. */<br>
|
||||||
|
}<br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Alternatively, use <tt>wglewIsSupported</tt> or
|
||||||
|
<tt>glxewIsSupported</tt> to check for extensions from a string:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
if (wglewIsSupported("WGL_ARB_pbuffer"))<br>
|
||||||
|
{<br>
|
||||||
|
/* OK, we can use pbuffers. */<br>
|
||||||
|
}<br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>Utilities</h2>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
GLEW provides two command-line utilities: 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>. The
|
||||||
|
Windows version creates a file called <tt>visualinfo.txt</tt>, which
|
||||||
|
contains a list of available OpenGL, WGL, and GLU extensions as well
|
||||||
|
as a table of visuals aka. pixel formats. Pbuffer and MRT 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. The Windows version
|
||||||
|
reports the results to a text file called <tt>glewinfo.txt</tt>. The
|
||||||
|
Unix version prints the results to <tt>stdout</tt>.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>Windows usage:</p>
|
||||||
|
<blockquote><pre>glewinfo [-pf <id>]</pre></blockquote>
|
||||||
|
|
||||||
|
<p>where <tt><id></tt> is the pixel format id for which the
|
||||||
|
capabilities are displayed.</p>
|
||||||
|
|
||||||
|
<p>Unix usage:</p>
|
||||||
|
<blockquote><pre>glewinfo [-display <dpy>] [-visual <id>]</pre></blockquote>
|
||||||
|
|
||||||
|
<p>where <tt><dpy></tt> is the X11 display and <tt><id></tt> is
|
||||||
|
the visual id for which the capabilities are displayed.</p>

<h1>The OpenGL Extension Wrangler Library</h1>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
The OpenGL Extension Wrangler Library (GLEW) is a cross-platform
|
||||||
|
open-source C/C++ extension loading library. GLEW provides efficient
|
||||||
|
run-time mechanisms for determining which OpenGL extensions are
|
||||||
|
supported on the target platform. OpenGL core and extension
|
||||||
|
functionality is exposed in a single header file. GLEW has been
|
||||||
|
tested on a variety of operating systems, including Windows, Linux,
|
||||||
|
Mac OS X, FreeBSD, Irix, and Solaris.

<h1>The OpenGL Extension Wrangler Library</h1>

|
|
||||||
|
<h2>Installation</h2>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
To use the shared library version of GLEW, you need to copy the
|
||||||
|
headers and libraries into their destination directories. On Windows
|
||||||
|
this typically boils down to copying:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<table border="0" cellpadding="0" cellspacing="0" align="center"> <!-- bgcolor="#f0f0f0" -->
|
||||||
|
<tr><td align="left"><tt>bin/glew32.dll</tt></td><td> to </td>
|
||||||
|
<td align="left"><tt>%SystemRoot%/system32</tt></td></tr>
|

<tr><td align="left"><tt>lib/glew32.lib</tt></td><td> to </td>

<td align="left"><tt>{VC Root}/Lib</tt></td></tr>
|
||||||
|
<tr><td align="left"><tt>include/GL/glew.h</tt></td><td> to </td>
|
||||||
|
<td align="left"><tt>{VC Root}/Include/GL</tt></td></tr>
|
||||||
|
<tr><td align="left"><tt>include/GL/wglew.h</tt></td><td> to </td>
|
||||||
|
<td align="left"><tt>{VC Root}/Include/GL</tt></td></tr>
|
||||||
|
</table>
|
||||||
|
<p>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
where <tt>{VC Root}</tt> is the Visual C++ root directory, typically
|
||||||
|
<tt>C:/Program Files/Microsoft Visual Studio/VC98</tt> for Visual
|
||||||
|
Studio 6.0 or <tt>C:/Program Files/Microsoft Visual
|
||||||
|
Studio .NET 2003/Vc7/PlatformSDK</tt> for Visual Studio .NET.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
On Unix, typing <tt>make install</tt> will attempt to install GLEW
|
||||||
|
into <tt>/usr/include/GL</tt> and <tt>/usr/lib</tt>. You can
|
||||||
|
customize the installation target via the <tt>GLEW_DEST</tt>
|
||||||
|
environment variable if you do not have write access to these
|
||||||
|
directories.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>Building Your Project with GLEW</h2>
|
||||||
|
<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. On Windows, you also need to
|
||||||
|
define the <tt>GLEW_STATIC</tt> preprocessor token when building a
|
||||||
|
static library or executable, and the <tt>GLEW_BUILD</tt> preprocessor
|
||||||
|
token when building a dll. 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:
|
||||||
|
</p>
|
||||||
|
<p class="pre">
|
||||||
|
#include <glew.h><br>
|
||||||
|
#include <GL/glut.h><br>
|
||||||
|
<gl, glu, and glut functionality is available here><br>
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
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 do not
|
||||||
|
need to include it separately.
|
||||||
|
</p>
|
||||||
|
<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 also need to
|
||||||
|
change the <tt>GLEW_BUILD</tt> preprocessor constant to
|
||||||
|
<tt>GLEW_STATIC</tt> when building a static library or executable,
|
||||||
|
otherwise you get build errors.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
<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:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
#include <GL/glew.h><br>
|
||||||
|
#include <GL/glut.h><br>
|
||||||
|
<gl, glu, and glut functionality is available here><br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
or:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p class="pre">
|
||||||
|
#include <GL/glew.h><br>
|
||||||
|
<gl and glu functionality is available here><br>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Remember 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
|
||||||
|
Unix (<tt>-lGLEW -lGLU -lGL</tt>).
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<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>.
|
||||||
|
