每当我包含文件qcustomplot.h时，就会出现大量错误。
我似乎无法解决这个问题，特别是因为它在Windows和Mac上运行良好。也许有人遇到了同样的问题。
以下是出现的错误消息：

创建全新的应用程序时，不会出现这些错误。
这就是我们如何包含文件的方式：
#include "qcustomplot/qcustomplot.h"
（是的，路径是正确的）
我们正在运行Qt 5.5。
提前致谢！
答案 0 :(得分：2)
感谢您的帮助，我们发现了错误。 事实上，它只是一条线需要重新订购.. 这是我们的主窗口：
#include <QMainWindow>
#include <QtWidgets>
#include "recognize.h"
#include "record.h"
#include "restrict.h"
#include "visualize.h"
#include "whitelist_dialog.h"
#include "qcustomplot/qcustomplot.h"
这是我们的识别：
#include <QtCore>
#include <QString>
#include <QWindow>
#include <QDebug>
#include <QDateTime>
#include <QCoreApplication>
#include "windowinfo.h"
#include "linux_x11.h"
这会导致错误。我们所要做的就是在
之后立即重新订购我们的recogn.h的包含#include qcustomplot/qcustomplot.h
感谢您的帮助！
永远记住，linux下qcustomplot includes的顺序非常重要！
