ROS 2 packages are found through CMake using find_package(). Therefore the CMAKE_PREFIX_PATH must not contain paths from ROS 1 which would overlay ROS 2 packages. Here are the steps for Linux and OSX. You should first build everything but the ROS 1 bridge with normal colcon arguments. ...
首先,我们需要确认kalibr包是否已经安装在你的ROS环境中。你可以通过ROS的包管理工具rospack或roscd尝试定位该包。 打开终端,运行以下命令尝试定位kalibr包: bash roscd kalibr 如果该命令返回了kalibr包的路径,说明包已经安装;如果返回了错误信息,说明包未安装或环境变量配置有误。如果...
lcm_ros_node这个node在deepstream_ros_bridge找不到,我们应该仔细检查cmakeLists文件,有可能使用launch文件启动时将节点程序的名称打错了,和cmakeLists文件中的程序名称进行对应即可,例如我的原本是lcm_ros_node节点,现在我改了代码变成了kafka_ros_node那么需要修改launch文件对应参数即可....
1、创建简单的功能包 catkin_create_pkg deb_demo roscpp rospy 创建一个.cpp文件,写上测试程序,并编译运行通过。 #include "ros/ros.h" #include <signal.h> void MySigintHandler(int sig) { ROS_INFO("shutting down!"); ros::shutdown(); ...
[rospack] Error: package 'robot_vision' not found 又是熟悉的错误,执行如下命令: rosrun robot_vision cv_bridge_test.py 报错: 说明package中没有robot_vision,上一次在roslaunch命令中也出现这个问题,最后通过catkin_make,和source devel/setup.zsh解决。 然后执行rosrun又是找不到robot_vision。 故技重施...
