操作系统: Ubuntu16.04
ROS版本: Kinetic
1.安装ROS,详情见http://blog.csdn.net/qq_17232031/article/details/79519308
2.建立一个catkin_ws文件夹,以及子目录src:
$ mkdir catkin_ws $ cd ./catkin_ws $ mkdir src3.在src目录下创建功能包,命名为first
$ catkin_create_pkg first此时会产生first文件夹,其中包含两个文件,CMakelists.txt和package.xml
4.在first文件夹下,新建hello.cpp文件
$ sudo gedit hello.cpp编写代码:
#include <ros/ros.h> int main(int argc,char ** argv) { ros::init(argc,argv,"hello_ros"); ros::NodeHandle nh; ROS_INFO_STREAM("Hello ROS"); }init函数初始化客户端库。NodeHandle节点句柄,用于程序与ROS的交互。
5.编译cpp代码,此时需要对同目录下的CMakelists.txt和package.xml文件进行修改
在CMakelist.txt文件中添加
add_executable(hello hello.cpp) target_link_libraries(hello ${catkin_LLIBRARIES})并且将
find_package(catkin REQUIRED)改为:
find_package(catkin REQUIRED COMPONENTS roscpp)这句是为了添加roscpp依赖项
修改package.xml文件,添加build_depend编译依赖和run_depend运行依赖
<build_depend>roscpp</build_depend> <run_depend>roscpp<run_depend>然后,在catkin_ws目录下执行:
$ catkin_make $ cd ./devel $ source setup.bash6. 运行程序
$ rosrun first hello出现结果:
