c++ - 错误 : no matching function for call to ‘sipqt_gui_cpp_RosPluginlibPluginProvider_ForPlugins::connectNotify(const char*&)’

Question

我在 Arch Linux ARM 上使用 ROS Indigo，我正在尝试从 AUR 安装软件包 ros-indigo-qt-gui-cpp。

但随后弹出如下错误:

过去 4 个小时我一直在谷歌搜索，但没有找到解决方案，甚至连线索都没有。我发现可能与此错误有关的所有内容都没有太大帮助。

我已经通过 qobject.h 文件来解决问题但没有成功(我是 C++ 的新手，所以我已经尽力了...)

我非常需要帮助。

如果我没有提供足够的信息，请告诉我，然后我将提供帮助解决此问题所需的任何其他信息或代码段。

提前致谢。

该包(与所有 ROS Indigo 包一样)需要 Qt4。似乎 sip-dev 生成的代码确实适用于 Qt4(其中使用了 connectNotify(const char * signal))，但您正在为 Qt5 编译它(其中函数被替换为 connectNotify (const QMetaMethod & signal)) - 因此出现错误消息。

一种解决方案可能是简单地删除 Qt5/降级到 Qt4。或者参见 https://wiki.archlinux.org/index.php/Qt关于如何选择默认 Qt 版本。
