Bug Summary and Steps to Reproduce

Bug Summary:

Intellisense does not aware of predefined macros from Clang. In my case __FILE_NAME__ macro

__FILE_NAME__ macro is one of the builtin macros from Clang Language Extensions - Link

Steps to reproduce:

Make a simple CMake Clang Project

mkdir clang_macro_test
cd  clang_macro_test

Create CMakeList.txt file

cmake_minimum_required(VERSION 3.7...3.26)

project(testProj, VERSION 1.0
        DESCRIPTION "Test project"
        LANGUAGES CXX)

set(CMAKE_EXPORT_COMPILE_COMMANDS ON)

add_executable(testProj main.cpp)

Create main.cpp

#include <iostream>

namespace {
    using std::cout, std::endl;
}

int main(int, char**) {
    __INT_FAST32_TYPE__ x = 1;
    const char* FILE_NAME = __FILE_NAME__;
    cout << __FILE_NAME__ << ":" << __LINE__ << endl;
    cout << "x: " << x << endl;

    return 0;
}

From CMake Tools, Select Kit Clang 14.0.3 arm64-apple-darwin22.5.0
Select Okay When CMake Tools asks user want to configure the project.
From the Visual studio code. Open project directort and open main.cpp. Error squiggle on the __FILE_NAME__

Check PROBLEMS tab.

    "startLineNumber": 9,
    "startColumn": 29,
    "endLineNumber": 9,

}]

Expected behavior:

No identifier "FILE_NAME" is undefined" error from the Intellisense.

Thank you for reporting this issue. I've filed an internal bug (1847073) against the IntelliSense engine code base that is shared with Visual Studio.

Michelle Matias (@michelleangela)

Michelle Matias (@michelleangela) wondering if there is any update on this

Sean McManus (@sean-mcmanus)

Sean McManus (@sean-mcmanus) or Colen Garoutte-Carson (@Colengms), could you follow-up?

Sean McManus (@sean-mcmanus)

Sean McManus (@sean-mcmanus) Colen Garoutte-Carson (@Colengms) any update on this?

Sharad (@thecoder138)

Sharad (@thecoder138) It hasn't been fixed yet. I added a message to the internal issue.

Is there any workaround?

Jay Patel (@jay1999ke)

Jay Patel (@jay1999ke) Not really. You could do something like

#if __INTELLISENSE__
#define __FILE_NAME__  __FILE__
#endif

and add that to a file specified as a forcedInclude.

This issue was reported against Clang. Please note that it affects GCC as well.

I'm seeing the same issue with GCC:

Since I'm using C_Cpp.default.compileCommands there also seems to be no way to silence (only this) warning since the default defines passed, e.g., with C_Cpp.default.defines are not applied to files that are part of the compilation database.

Sean McManus (@sean-mcmanus)

Sean McManus (@sean-mcmanus) are there any plans to address this?

martin (@lmapii)

martin (@lmapii) The issue is still open. I've ping'd the team to check (my last ping was a year ago).

martin (@lmapii)

martin (@lmapii) It looks like this ping worked, i.e. it looks like it's "moving forward", but we don't have an ETA on a fix.

Sean McManus (@sean-mcmanus)

Sean McManus (@sean-mcmanus) that's good news, thank you!

Seungwon Lee (@Malangcow)

Seungwon Lee (@Malangcow) martin (@lmapii) Sharad (@thecoder138) Mobilinkd LLC (@mobilinkd) Jay Patel (@jay1999ke) Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.27.1

However, this change causes a crash in some scenarios: #13866 . We should have a fix out later today in 1.27.2.

The crash should be fixed now (it could randomly crash when __BASE_NAME__ was parsed). With https://github.com/microsoft/vscode-cpptools/releases/tag/v1.27.2

I installed 1.27.2 and it's looking good for what wasn't working for me!
