code blocks 中glut设置

本文介绍了解决GLUT库与不同C运行时库(CRT)链接导致的问题的方法。通过定义GLUT_DISABLE_ATEXIT_HACK宏避免了atexit回调不被调用的情况,并给出了一个简单的OpenGL程序示例。

在#include <GL/glut.h>前加#define GLUT_DISABLE_ATEXIT_HACK 

Win32 has an annoying issue where there are multiple C run-time
libraries (CRTs). If the executable is linked with a different CRT
from the GLUT DLL, the GLUT DLL will not share the same CRT static
data seen by the executable. In particular, atexit callbacks registered
in the executable will not be called if GLUT calls its (different)
exit routine). GLUT is typically built with the
"/MD" option (the CRT with multithreading DLL support), but the Visual
C++ linker default is "/ML" (the single threaded CRT).
One workaround to this issue is requiring users to always link with
the same CRT as GLUT is compiled with. That requires users supply a
non-standard option. GLUT 3.7 has its own built-in workaround where
the executable's "exit" function pointer is covertly passed to GLUT.
GLUT then calls the executable's exit function pointer to ensure that
any "atexit" calls registered by the application are called if GLUT
needs to exit.

Note that the __glut*WithExit routines should NEVER be called directly.
To avoid the atexit workaround, #define GLUT_DISABLE_ATEXIT_HACK. */

其他一样

#include <windows.h>

#define GLUT_DISABLE_ATEXIT_HACK

#include <GL/glut.h>

#include <stdlib.h>

 

int main(int argc, int *argv[])

{

  glInit(&argc, argv);

  glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE | ...);

     glutInitWindowPosition(100, 100);

     glutInitWindowSize(400, 400);

     glutCreateWindow("...");

     glutDisplayFunc(&...);

     glutMainLoop();

  return 0;

}
