#include errors detected in vscode

Close and re-open Visual Studio Code.

If you are working with cmake-tools and the error messages says something is wrong with the configurationProvider, then you have 2 options:

1. Use ms-vscode.cpptools instead of ms-vscode.cmake-tools
2. Define the headers in CMakeLists.txt

Option 1: Use ms-vscode.cpptools instead of ms-vscode.cmake-tools.

1. Open c_cpp_properties.json. (windows key on windows or cmd key on mac + shift + p, enter "c/c++ edit configurations" and chose 'json'.
2. Enter ms-vscode.cpptools as value for configurationProvider instead of ms-vscode.cmake-tools or whatever you have.

How it should look like after the replacement of configurationProvider:

One other important configuration is the include path. The assumption is that you have this configuration right. May be like following

Option 2: Define the headers in CMakeLists.txt

When configurationProvider is set to ms-vscode.cmake-tools in c_cpp_properties.json, VS Code uses the include information defined in the CMakeLists.txt instead of reading the includePath configs in VS Code.

So you need to setup the include path correctly:

1. using the include_directories command (rather than the target_include_directories command) to define the headers
2. Configure the project to reflect the change happened in the previous step.

• Left mouse click on the bulb of error line
• Click Edit Include path
• Then this window popup

• Just set Compiler path

I ended up here after struggling for a while, but actually what I was missing was just:

If a #include file or one of its dependencies cannot be found, you can also click on the red squiggles under the include statements to view suggestions for how to update your configuration.

The error message "Please update your includePath" does not necessarily mean there is actually a problem with the includePath. The problem may be that VSCode is using the wrong compiler or wrong IntelliSense mode. I have written instructions in this answer on how to troubleshoot and align your VSCode C++ configuration with your compiler and project.

I was trying a hello world program, and this line:

#include <stdio.h>

was underlined green. I tried:

1. Deleting the line
2. Re-writing the line
3. Clicking the yellow bulb and choosing to update

fixed the error warning. i don't know if it fixed the actual problem. But then i'm compiling via a linux VM on Windows 10

Go to your c_cpp_properties.json file by searching from settings.There you might see the following code

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "gnu17",
            "cppStandard": "c++17",
            "intelliSenseMode": "linux-gcc-x64"
        }
    ],
    "version": 4
}

Change the compiler path as below

"compilerPath": "/usr/bin/g++",

After closing and reopening VS, this should resolve.

For me, using Ubuntu, I just had to install gcc to solve this issue.

sudo apt install gcc

Then, set the compiler path to gcc. Go to your c_cpp_properties.json file, set:

"compilerPath": "/usr/bin/gcc"

An alternative answer would be opening VS Code in remote WSL, if you going to compile files with g++. Just close your VS Code and open WSL and type code . After that the File Explorer shows that VS Code is now running in the context of WSL with the title bar [WSL: Ubuntu]. But make sure you'd installed the GNU compiler tools and the GDB debugger on WSL.

• For Windows:

1.Install Mingw-w64

2.Then Edit environment variables for your account "C:\mingw-w64\x86_64-8.1.0-win32-seh-rt_v6-rev0\mingw64\bin"

3.Reload

• For MAC

  1.Open search ,command + shift +P, and run this code “c/c++ edit configurations (ui)”

  2.open file c_cpp_properties.json and update the includePath from "${workspaceFolder}/**" to "${workspaceFolder}/inc"

If someone have this problem, maybe you just have to install build-essential.

apt install build-essential

In my case I did not need to close the whole VS-Code, closing the opened file (and sometimes even saving it) solved the issue.

I had luck removing the comments from c_cpp_properties.json in the .vscode folder. Comments aren't permitted in json files by default and you can't simply rename it .jsonc. Referenced In VS Code, disable error "Comments are not permitted in JSON"

My header file was in include/head.h, code in src/code.cpp. I wrote

#include "head.h"

and got this error. Changing it to

#include "../include/head.h"

fixed it.

I solved this problem, once I removed configurationProvider node and set cStandard and cppStandard to default values:

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}",
                "${workspaceFolder}/**",
                "${workspaceFolder}/test",
                "/opt/qt5/include/QtCore",
                "${workspaceFolder}/test"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/clang",
            "cStandard": "${default}",
            "cppStandard": "${default}",
            "intelliSenseMode": "linux-clang-x64"
        }
    ],
    "version": 4
}

For Windows:

1. Please add this directory to your environment variable(Path):

C:\mingw-w64\x86_64-8.1.0-win32-seh-rt_v6-rev0\mingw64\bin\

2. For Include errors detected, mention the path of your include folder into

"includePath": [ "C:/mingw-w64/x86_64-8.1.0-win32-seh-rt_v6-rev0/mingw64/include/" ]

, as this is the path from where the compiler fetches the library to be included in your program.

In case you've copied and pasted code into your new file in VS Code

Please delete #include <iostream> and try to build again.
