VSCode添加头文件路径解决“cannot open source file “xxxx.h“”

ゝ一世哀愁。 2022-11-13 06:29 4271阅读 0赞

在下在使用VSCode的时候遇到了以下问题\#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (/home/pi/works/mqtt\_demo/mqtt\_client.c).C/C++(1696)，虽然说我实际开发编译是通过编写Makefile实现的，对我实际开发并不造成影响，但是IDE老是那么红着，显示 ERROR  ，实属不雅：

  那么问题来了，**怎么给VSCode添加头文件的搜索路径呢？**  
1）在vscode中按Ctrl+Shift+P 输入configuration，选择C/C++：Edit Configuration(JSON)；

2）编辑打开的c\_cpp\_properties.json文件，在configurations里的includePath中添加你需要引入的头文件的路径，保存即可。  
**修改前：**

{
        
        "configurations": [
            {
        
                "name": "Linux",
                "includePath": [
                    "${workspaceFolder}/**"
                ],
                "defines": [],
                "compilerPath": "/usr/bin/gcc",
                "cStandard": "gnu17",
                "cppStandard": "gnu++14",
                "intelliSenseMode": "linux-gcc-arm"
            }
        ],
        "version": 4
    }

**修改后：**

{
        
        "configurations": [
            {
        
                "name": "Linux",
                "includePath": [
                    "${workspaceFolder}/**",
                    "/usr/local/include/cjson/**"
                ],
                "defines": [],
                "compilerPath": "/usr/bin/gcc",
                "cStandard": "gnu17",
                "cppStandard": "gnu++14",
                "intelliSenseMode": "linux-gcc-arm"
            }
        ],
        "version": 4
    }

修改完成后，不显示 ERROR  了。
