构建OpenCV程序时出现错误"No rule to make target ..."，并"undefined reference to"错误

Question

我想构建我的简单opencv程序，但是当我构建项目时，它失败了，错误描述为：

No rule to make target `/usr/lib/x86_64-linux-gnu/libconsole_bridge.so,opencv_videostab', needed by `/home/turtlebot/catkin_ws/devel/lib/multi_robot_slam/imageConverter'. Stop.

这是我的cmakelists.txt：

cmake_minimum_required(VERSION 2.8.3)
project(robot_slam)
find_package(catkin REQUIRED
  COMPONENTS
    cmake_modules
    roscpp
    sensor_msgs
    cv_bridge
    std_msgs
    image_transport
)
find_package(OpenCV REQUIRED)
include_directories(include ${catkin_INCLUDE_DIRS} ${OpenCV_INCLUDE_DIRS})
catkin_package()
add_executable(imageConverter src/imageConverter.cpp)
target_link_libraries(imageConverter ${catkin_LIBRARIES} ${OpenCV_LIBRARIES})

有人知道问题是什么以及如何解决吗？

Answer 1

我终于通过修改逗号到空间解决了我的问题。从中，我了解到：

No rule to make target /usr/lib/x86_64linux-gnu/libconsole_bridge.so,opencv_videostab', needed by /home/turtlebot/catkin_ws/devel/lib/multi_robot_slam/imageConverter'.Stop.   

意味着某人通过逗号而不是空间错误地列举了库。

，此外，我还解决了

的问题

undefined reference to ***.

这些问题通常意味着没有库，或者您的计算机上有多个版本。对我来说，这是因为#include<>使用了OpenCv3.2的标头文件，而LIB使用了OpenCV2.4.SO。我将find_package(OpenCV REQUIRED)修改为find_package(OpenCV 3 REQUIRED)以使使用的lib也是OpenCv3.2。
