qt项目中的QtXml/qdom.h问题

我正在QT creator Fedora 27上的一个项目中使用CGAL、libQGLViewer库

但它在库的头文件上显示错误

编译输出：

所有错误都出现在QtXml/qdom.h文件中，我不知道如何解决它们 谢谢你的帮助，

谢谢

您最好提供帮助以获得更好的帮助您使用的是什么版本的Qt和QGLViewer？@mgimeno QGLViewer库版本2.6.3。它应该与QGLViewer 2.6一起使用，我们在演示中使用了一段时间。不过，您至少需要Qt5.4。您可以在CGAL的演示中找到示例设置，比如在包AABB_树中。仔细看看里面的CMakeLists.txt，我想你是不见了。无论如何，这些错误看起来像是由以前包含的文件中缺少的

生成的，可能值得检查。
