错误：没有匹配的函数调用'sipqt_gui_cpp_RosPluginlibPluginProvider_ForPlugins :: connectNotify（const char *＆）'

Question

我使用ROS Indigo与Arch Linux ARM，我试图安装包ros-indigo-qt-gui -URP来自AUR。

但这时会弹出以下错误：

我一直在使用Google最后4小时，还没有得到解决，甚至也不是一个线索。所有我发现可能与这个错误有关，并没有太多帮助。

我已经通过qobject.h文件旨在解决这个问题，但没有成功了（我是C++非常新手，所以我做了我最好的...）

我强烈需要帮助。

如果我没有提供足够的信息，请告诉我，然后我会提供任何其他信息或代码段来帮助解决此问题。

在此先感谢。

这个软件包（与所有ROS Indigo软件包一样）都需要Qt4。似乎由sip-dev生成的代码确实用于Qt4（其中使用了connectNotify(const char * signal)），但是您正在编译它用于Qt5（其中函数被替换为connectNotify(const QMetaMethod & signal)） - 因此是错误消息。

一个解决方案可能是简单地删除Qt5 /降级到Qt4。另请参阅​​关于如何选择默认Qt版本。
