#include "GL/freeglut.h" 在将其添加到 C++ wxWidgets 代码、CodeBlocks 时会产生构建错误

Question

我正在尝试编写一个同时包含 wxWidgets 和 OpenGL ( FreeGLUT & GLEW ) 的应用程序。我在 Win 7 机器上使用 CodeBlocks & C++。到目前为止，我已经编写了一些构建和正常工作的 wxWidgets 代码。但是当我添加该行时：

#include "GL/freeglut.h"

程序没有正确构建，我收到这些错误（在 winundef.h 中）：

O:\SourceCode\Libraries\wxWidgets3.0\include\wx\msw\winundef.h||In function 'HWND__* CreateDialog(HINSTANCE, LPCTSTR, HWND, DLGPROC)':|

这个问题的原因是什么以及如何解决？

解决方案正在移动

#include "GL/glew.h"
#include "GL/freeglut.h"

在 wxWidgets 头文件之后。
