- 前提条件：安装好了ROS（melotic) 和 VSCODE
1、vscode安装必要的插件
2、提前准备好一个ROS的catkin workspace
在workspace下面使用vscode打开
$ code .
打开之后，第一步安装的ROS插件就会自动识别到这个workspace，同时会出现一个文件夹.vscode
里面有两个json文件：
c_cpp_properties.json
settings.json
c_cpp_properties.json 主要是和头文件 ros/ros.h这种头文件包含有关系。
settings.json 暂时好像是和Python的自动补全有关系。
3、将catkin_make放到vscode里面编译
原来的方式是，在catkin_ws下使用catkin_make命令：如下
hou@hou-ThinkPad-P52s:~/catkin_ws$ catkin_make
Base path: /home/hou/catkin_ws
Source space: /home/hou/catkin_ws/src
Build space: /home/hou/catkin_ws/build
Devel space: /home/hou/catkin_ws/devel
Install space: /home/hou/catkin_ws/install

现在讲述如何在vscode里面实现。
请阅读vscode编译的task讲解，了解task的作用。
task其实就是把命令写在这个文件里，然后调用运行这个文件。
点击菜单栏： Terminal->Configure default build task，然后生成在.vscode的文件夹出现并同时打开一个task.json文件。
c_cpp_properties.json
settings.json
task.json
将task.json 文件内容改成如下
{
"version": "2.0.0",
"tasks": [
{
"label": "catkin_make",
"type": "shell",
"command": "catkin_make",
"args": [
"-j4",
"-DCMAKE_BUILD_TYPE=Release",
"-DCMAKE_EXPORT_COMPILE_COMMANDS=1",
"-DCMAKE_CXX_STANDARD=14"
],
"problemMatcher": [
"$catkin-gcc"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
ctrl + shift+B 点击 catkin_make 之后在devel下面会生成一个compile_commands.json的文件
compile_commands.json的内容：
[

其实就是规定了到哪里去编译什么文件。
4、在vscode里面编译catkin_ws
5、使用vscode打开roscore
Ctrl +Shift+p
ROS:Start Core
6、运行功能包节点
ROS:Run a Ros excutable (rosrun)
回车，输入并按照提示选择
beginer_tutorials
回车，输入并按照提示选择
talker
