c++ - 'glutInitDisplayMode' 未在此范围内为 Windows 7 上的 C++ 中的 Qt 声明

Question

我正在尝试使用 C++ 在 Windows 7 上的 Qt Creator 中运行程序。我已将 GL/glut.h 更改为 GL/glu.h 但是当我运行它时，出现以下错误:C:\CSC\Qt\Projects\QTunes\glwidget.h:51: 错误:“GLUT_DOUBLE”未在此范围内声明C:\CSC\Qt\Projects\QTunes\glwidget.h:51: 错误:'GLUT_RGB' 未在此范围内声明C:\CSC\Qt\Projects\QTunes\glwidget.h:51: 错误:“GLUT_DEPTH”未在此范围内声明C:\CSC\Qt\Projects\QTunes\glwidget.h:51: 错误:'glutInitDisplayMode' 未在此范围内声明

这是我在 stackvoerflow 上的第一篇文章，如果格式不正确，请见谅，但这是代码:

您可以在 .pro 文件中添加:

LIBS += -lglut
