#include <QtWidgets> 在带有 ros kinetic ubuntu 16.06 的 Qt 5.5 中不起作用

Question

我有一个 ros-project 可以在 ubuntu 14.04 上的 ros-indigo 下构建良好 现在我切换到 ros-kinetic 和 ubuntu 16.04，构建代码时出现以下错误：

错误 * [CMakeFiles/rviz_satellite.dir/src/moc_aerialmap_display.cpp.o] 错误 1 make[2]: 等待未完成的工作......在包含的文件中 /home/kohaf3/opel_ws/src/rviz_satellite/src/aerialmap_display.cpp:45:0: /home/kohaf3/opel_ws/src/rviz_satellite/src/aerialmap_display.h:43:21: 致命错误：QtWidgets：没有这样的文件或目录编译 终止。制作[2]: [CMakeFiles/rviz_satellite.dir/src/aerialmap_display.cpp.o] 错误1 make[1]: * [CMakeFiles/rviz_satellite.dir/all] 错误 2 make: *** [全部] 错误 2

我还安装了 Qt creator ros 插件，请参见此处 (https://github.com/ros-industrial/ros_qtc_plugin/wiki/1.-How-to-Install-(Users))

Answer 1

这对我有用：

if (UseQt5)
        find_package(Qt5 COMPONENTS Core Gui Network Widgets Concurrent REQUIRED)
        message("qt5 is used")
        # Find Qt5Core and Qt5Widgets
        find_package(Qt5Core REQUIRED)
        find_package(Qt5Widgets REQUIRED)
        # For finding Qt includes
        include_directories(${CMAKE_CURRENT_SOURCE_DIR})
        include_directories(${Qt5Widgets_INCLUDE_DIRS})
        include_directories(${Qt5Core_INCLUDE_DIRS})

else()
        find_package(Qt4 COMPONENTS QtCore QtGui QtNetwork QtWidgets REQUIRED)
    include(${QT_USE_FILE})
        message("qt4 is used")
endif()

我认为您还必须在 CMake 中包含来自 Qt 的 Widgets/QtWidgets 模块：

if (UseQt5)
    find_package(Qt5 COMPONENTS Core Gui Network Concurrent Widgets REQUIRED)
        message("qt5 is used")
else()
    find_package(Qt4 COMPONENTS QtCore QtGui QtNetwork QtWidgets REQUIRED)
    include(${QT_USE_FILE})
        message("qt4 is used")
endif()
