FreeGLUT users should normally just include GL/glut.h in their programs.
|
||||||
|
Programs which need FreeGLUT-specific functions should also include
|
||||||
|
GL/freeglut_ext.h as follows:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<pre>
|
||||||
|
#include <GL/glut.h>
|
||||||
|
#ifdef FREEGLUT
|
||||||
|
#include <GL/freeglut_ext.h>
|
||||||
|
#endif
|
||||||
|
</pre>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Compile-time FreeGLUT version testing can be done as follows:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<pre>
|
||||||
|
#ifdef FREEGLUT_VERSION_1_4
|
||||||
|
code specific to FreeGLUT 1.4 or later here
|
||||||
|
#endif
|
||||||
|
</pre>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
In future releases, FREEGLUT_VERSION_1_5, FREEGLUT_VERSION_1_6, etc will
|
||||||
|
be defined. This scheme mimics OpenGL conventions.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
The FreeGLUT version can be queried at runtime by calling
|
||||||
|
glutGet(GLUT_VERSION).
|
||||||
|
The result will be X*10000+Y*100+Z where X is the major version, Y is the
|
||||||
|
minor version and Z is the patch level.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
This may be used as follows:
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<pre>
|
||||||
|
if (glutGet(GLUT_VERSION) < 10300) {
|
||||||
|
printf("Sorry, you need FreeGLUT version 1.3.0 or later to run this program.\n");
|
||||||
|
exit(1);
|
||||||
|
}

||||||
