In the case of compilation, intellisense always indicates that the header file cannot be found

[sean-mcmanus]

Are you trying to compile with cl.exe? Did you run CMake: Configure? When you run C/C++: Log Diagnostics with a C++ file active what is the output in regards to system includes?

[shawn1j]

Here is my configuration result, but it didn't work

[sean-mcmanus]

@shawn1j Yeah, can you check the C/C++: Log Diagnostics output with a C/C++ file active?

Or if you set C_Cpp.loggingLevel to "Debug" and check the "C/C++" logging for message "Custom configurations received:" that will show what receive from the CMake Tools extension after opening a file.

[shawn1j]

This is my c/c + + log output (because there is too much content, I stored it in the file):

c++ loging .txt

[shawn1j]

This is my cmake output

[sean-mcmanus]

@shawn1j Your logging indicates CMake Tools is not sending us any configuration info for the header files that are opened, i.e. it doesn't appear that you're configured correctl or it could be a CMake Tools issue.

[v-frankwang]

@shawn1j Thank you for reporting this issue. Regarding this issue, we tried to reproduce this issue using a simple demo project however we were unable to reproduce this issue for you. In order to investigate further, please provide us with a simple demo project to reproduce the issue and we look forward to your feedback.

[shawn1j]

Of course, here's my case, and it's very simple.

CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

project(demo LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED True)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

add_executable(demo main.cpp )

main.cpp

#include <iostream>

int main(int argc, char **argv)
{
    std::cout << "Hello World" << std::endl;
  
    return 0;
}

The following is the output of cmake-tools, because c/ C ++ output too much information, I put it in the c_cpp.logging.txt file.

Environment

• OS and Version: windows 10 x64
• VS Code Version: 1.90
• C/C++ Extension Version: 1.20.5
• CMake Version: 3.24.2
• Visual Studio 2022 Version: v17.10.1

[v-frankwang]

@shawn1j I'm very sorry, I don't get this error with the code you provided, can you give me some advice?

[shawn1j]

Sorry to keep you waiting, I tried to use the latest version of cmake (version 3.29.6). After my testing, I found that when I used Visual Studio 2022 Developer Command Prompt v17.10.1 to launch vs code, vs code intellisense will work properly. This did not work with cmake (version 3.24.2), which I used earlier.

Here is the effect of starting vs code without Visual Studio 2022 Developer Command Prompt v17.10.1.

I wonder if this has anything to do with my computer environment. can you give me some advice?

[v-frankwang]

@shawn1j When I start vscode without Visual Studio 2022 Developer Command Prompt I get a generator not found, which should be normal because my generator is installed by installing VS and not separately, but I still can't reproduce the problem you described.
