解决VS 2010调用OpenGL时遇到的问题:error LNK2019

引自：http://blog.csdn.net/jasonleesjtu/article/details/8700167

问题1、error LNK2019: unresolved external symbol __imp____glutInitWithExit@12 referenced in function _glutInit_ATEXIT_HACK@8

solution:

Try define the following line right before including the header, glut.h.

#define GLUT_DISABLE_ATEXIT_HACK

为什么出现这个错误，这是我在网站上找到的原因，和大家分享一下：

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. */
