C++ 未定义对'qInitResources_systray（）'；

我使用qt并获取错误：

/media/roroco/disk750/Downloads/qtbase/examples/widgets/desktop/systray/main.cpp:50: undefined reference to `qInitResources_systray()'

这是我的CMakeLists.txt

SET(CMAKE_PREFIX_PATH /media/roroco/disk750/Downloads/qtbase)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
find_package(Qt5Widgets)
add_executable(systray main.cpp window.cpp)
target_link_libraries(systray Qt5::Widgets)

cmake_minimum_required(VERSION 3.3)
project(systray)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

SET(CMAKE_PREFIX_PATH /media/roroco/disk750/Downloads/qtbase)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
find_package(Qt5Widgets)
add_executable(systray main.cpp window.cpp systray.qrc)
target_link_libraries(systray Qt5::Widgets)

如何使此示例工作

根据错误消息

未定义对'qInitResources\u systray（）'的引用

，我应该使用以下CMakeLists.txt

SET(CMAKE_PREFIX_PATH /media/roroco/disk750/Downloads/qtbase)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
find_package(Qt5Widgets)
add_executable(systray main.cpp window.cpp)
target_link_libraries(systray Qt5::Widgets)

cmake_minimum_required(VERSION 3.3)
project(systray)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

SET(CMAKE_PREFIX_PATH /media/roroco/disk750/Downloads/qtbase)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
find_package(Qt5Widgets)
add_executable(systray main.cpp window.cpp systray.qrc)
target_link_libraries(systray Qt5::Widgets)

你忘记的是qrc文件。您可以使用qt5\u add\u resources将其添加到CMakeLists中，因为我在

CMake

中遇到了同样的问题，这很有帮助。结果是变量名不匹配，因为我使用了自定义的

CMake

helper函数，因此Qt4和Qt5可以由同一个CMakeLists.txt处理；我在

add\u executable

调用中缺少了（我的等价物）

systray.qrc
