【问题讨论】：
【参考方案1】：您的编译（或更具体地说，链接）过程中似乎没有包含 QtOpenGL 模块。
如果您在项目中使用.pro 文件，则需要在其中添加QT += opengl，以告知qmake 您正在使用QtOpenGL。其他构建系统可能需要您执行不同的操作。
使用 NetBeans 管理配置时，如果进入项目属性，在 Build -> Qt 下，应该有各种 Qt 模块的复选框，包括 QtOpenGL。您可以在此处启用/禁用与任何 Qt 模块的链接。
【讨论】：
在NetBeans中，没有.pro文件，不知道怎么把这个语句加到这个文件里 根据输出，它似乎确实使用了qmake 和.pro 文件nbproject/qt-Debug.pro，至少在内部是这样。如果你进入项目的属性，在 Build -> Qt 下，应该有各种 Qt 模块的复选框，包括QtOpenGL。
这为我节省了数小时的调试时间！谢谢！以上是关于NetBeans 不编译 openGL 项目的主要内容，如果未能解决你的问题，请参考以下文章
