When started up with Visual Studio Code , This problem happened.

Thanks for help...

Do you have the C/C++ Extension installed?

I'm struggling to remember what I did to fix this, but I believe it's a matter of letting or making the C/C++ extension use build/compile_commands.json to find the proper include path.

compile_commands.json is available after you've done your first build.

Hello,
These combination of the extension version works for me.
c/c++ ver 1.1.3
Espressif idf 0.5.1

Also to get rid of the error lines, you need to build the project first. Only after that vscode will be able to find the headers. Thanks!

I had he same problem, I downloaded MinGW compiler then I added his directory to the "environment variable" -or something like that- then it was solved, but the build failes, and there is an error in he C/C++ cofiguration (UI) displaying:

Cannot find: ${env:IDF_PATH}/components/
Cannot find: ${env:ADF_PATH}/components/
Cannot find: ${env:ADF_PATH}/components/

and I'm searching for a solution right now.

Add compile_commands.json to your c_cpp_properties.json

Code: Select all

"compileCommands": "${workspaceFolder}/build/compile_commands.json"

I have the same issue and am following along. How do I " Add compile_commands.json to your c_cpp_properties.json"

Currently my c_cpp_properties.json file is

{

"${config:idf.espIdfPath}/components/**"
],

},
