C++ Windows 8 64位上Visual Studio 2013的OpenGL GLut链接问题

首先我从这个来源下载了glut，http://user.xmission.com/~nate/glut.html“>内特·罗宾斯。我说： 将glut32.dll转换为C:\Windows\SysWOW64， glut32.lib转换为C:\Program Files（x86）\Microsoft Visual Studio 12.0\VC\lib glut.h转换为C:\Program Files（x86）\Microsoft Visual Studio 12.0\VC\include\GL

在VisualStudio中，在C++下，我创建了一个空的项目，将编译器改为64×x。我确定选择所有的配置并链接OpenGL32.LIB、GL32.LIB和GLUT32.LIB。 在工具->选项->VC++目录->包含文件中：C:\Program Files（x86）\Microsoft Visual Studio 12.0\VC\Include 在配置属性中→ 连接器→ 其他库目录：C:\Program Files（x86）\Microsoft Visual Studio 12.0\VC\lib

    - display: Automatically called when the window is first opened.
    Later, when the frame content needs to be changed, we need
    to call display again From the Program to re-draw the objects.
    This is essential for animation.
    - reshape: Automatically called when the window is first opened,
    or when the window is re-sized or moved by the user.
    - keyboard: Automatically called when a keyboard event occurs.
    - mouse:    Automatically called when a mouse event occurs.
    - idle:     Automatically called when nothing occurs.
    This is essential for animation.

    * Once entering the event loop, the execution control always returns to
    the event loop. When particular event occurs, the corresponding call-back
    function is called; when that call-back function finishes, control again
    goes back to the event loop, and the process is repeated.

无法找出我做错了什么。

您使用的是32位库，但您正在编译x64可执行文件，而链接器无法解析符号。

@Bokucius我下载的文件说是64位的。这是否意味着即使我的C:\Windows\SysWOW64中有一个opengl32.dll，我仍然需要用win32编译它？SysWOW64用于32位dll（），在您提供的url中显示“GLUT for win32”“现在我明白了。谢谢。@Bokucius我下载的文件说是64位的。这是否意味着即使我的C:\Windows\SysWOW64中有一个opengl32.dll，我仍然需要用win32编译它？SysWOW64是用于32位dll（），您提供的url中写着“GLUT for win32”，我现在明白了。谢谢
