• C/C++ Extension Version: 1.8.4
• Other extensions you installed (and if the issue persists after disabling them):
• A clear and concise description of what the bug is.

To Reproduce Please include a code sample and launch.json configuration. Steps to reproduce the behavior:

1. Go to 'install vscode and install cpptools'
2. Click on 'create cpp file， two funcitons'
3. can not navigation function
4. See error

link vscode issue: https://github.com/microsoft/vscode/issues/142945

Additional context If applicable, please include logging by adding "logging": { "engineLogging": true, "trace": true, "traceResponse": true } in your launch.json Add any other context about the problem here including log or error messages in your Debug Console or Output windows.

@lifw555 Could you share the sample code or full source cpp file that reproduces this behavior on the breadcrumbs navigation bar?

Could you also share the log from running the command C/C++: Log Diagnostics?

[lifw555]

main.cpp

#include <iostream>
#include <windows.h>

using namespace std;

void test()
{
    cout << "11111111" << endl;
}

int main(int argc, char *argv[]) 
{
    //MessageBox(NULL, "START", "hello test", 0);

    cout << "hello test!!!-1" << endl;

    test();
    //111

    //Sleep(5*1000);

    //char c = getchar();
    //cout << "c:" << c <<endl;

    cout << "hello test!!!-2" << endl;
    return 0;
}

how to get "Log Diagnostics" ?

[lifw555]

just install this extension, no others .

[lifw555]

befor vscode 1.64.0 , it works.

update to 1.64.0 above, it can not work.

[michelleangela]

@lifw555 I was not able to reproduce the issue using the sample code.

It could be the extension did not install correctly on your machine after updating VS Code to 1.64.0. Could you try uninstalling the C/C++ extension, and then make sure the folder of the extension (path C:\Users\%username%\.vscode\extensions\ms-vscode.cpptools-1.8.4) is deleted after uninstalling? And then re-install the extension again?

If re-installing seems to have worked and code navigation is still not working, could you send logs by following these instructions https://code.visualstudio.com/docs/cpp/enable-logging-cpp#_enable-logging-for-the-language-server?

[lifw555]

sorry ，i use mingw32-8.1.0-posix-dwarf ， not vs.

[michelleangela]

@lifw555 Could you send logs by following these instructions https://code.visualstudio.com/docs/cpp/enable-logging-cpp#_enable-logging-for-the-language-server? The logs will show what the extension is trying to do and if the extension was successful in getting the include paths from the compiler that you use. The logs will help further investigate the issue.

Also, did you try uninstall and reinstall the extension?

[lifw555]

yes, uninstall and reinstall . vscode and extension all done .

later ， i will do that follow your instructions.

[lifw555]

this vscode and extension all new installed.

After closing VS Code instances, you should verify that no dangling cpptools processes exist that could have a lock on the database. Also, when you run "C/C++: Reset IntelliSense Database" do you see a tag parsing file: <path>/main.cpp message in the logging?

What does the Explorer->Outline view show?

[michelleangela]

Also, could you check if any breadcrumb settings are configured.

Breadcrumb settings:

[lifw555]

it is checked。

after closeing VS Code instances, I confirm that this process “cpptools” is not in the process list

nothing in Explorer->Outline view！

[lifw555]

after start VS Code instances， in the processing list , has 2 processes about cpp:

[sean-mcmanus]

Ah, the error "Tag parsing encountered an error, but it may not matter. Let us know if symbols in the file can't be found:" is not expected in this case. It appears something is causing a tag parser failure. That appears to be the cause of the breadcrumb not working.

[lifw555]

any other information need to provide ？

[sean-mcmanus]

@lifw555 No. Thanks for providing the previous info.

[lifw555]

ok

[sean-mcmanus]

@lifw555 What encoding is the file? UTF-8 or something else? It should show in the bottom right status bar when the file is active.

[lifw555]

utf-8

[lifw555]

[sean-mcmanus]

@lifw555 Does the issue repro with code

void test()
{
}

int main(int argc, char *argv[]) 
{
    test();

    return 0;
}

or do you know what the minimum repro is?

[lifw555]

your code is reproducible

[lifw555]

my code

include

void test() { printf("this is test.\n"); }

int main(int argc, char const *argv[]) { test(); return 0; }

[sean-mcmanus]

Do you have any files named cpp.hint in the directory where the main.cpp exists or in any parent directory?

[lifw555]

no such file

[sean-mcmanus]

Is there any scenario where you are able to get symbols in the breadcrumbs or Outline view? What about with a main.ts (TypeScript) file with

function foo()
{

}

[sean-mcmanus]

Also, if you add int global_var; at the top of the main.cpp file do you see that symbol in the Explorer->Outline view after saving?

[lifw555]

int global_var;

not have.

[lifw555]

function foo() {

}

this work

[lifw555]

[lifw555]

c++ not work

[sean-mcmanus]

Also, the files.exclude and C_Cpp.files.exclude settings could also cause the breadcrumb to not appear (if they match the main.cpp or its folder), but in that case you wouldn't get the "tag parse" message.

Other than that, unfortunately, I think we're all out of ideas as to what could be causing our tag parser to fail for you, so I don't think we'd be able to fix it unless we think of something else.

[lifw555]

:-(

[lifw555]

not set "files.exclude" and "C_Cpp.files.exclude".

[lifw555]

Degraded version (vscode 1.57.1), and install the extensions

it works.

?

[sean-mcmanus]

Ah, one more idea, can you try setting `"C_Cpp.default.browse.databaseFilename": "${workspaceFolder}/.vscode/vc.db" (it's also settable via the property in the c_cpp_properties.json via the "databaseFilename" property of a "browse" property) -- it's possible the default database location may not have write permissions for some unusual reason.

[sean-mcmanus]

Hmm...downgrading to VS Code 1.57.1 uses which version of the C/C++ extension? You might also try switching back to VS Code 1.64.2 or 1.65.0 and instead downgrading the C/C++ extension to an earlier version? If the issue doesn't repro with an older C/C++ extension, that would imply it's some regression in our code.

[lifw555]

1.65.0 ?

the latest version is 1.64.2.

and after switch back , it is not work .

[lifw555]

vscode : 1.57.1 C/C++ extension : 1.5.1

[lifw555]

it is vscode bug?

[sean-mcmanus]

1.65.0 is VS Code Insiders.

Does the bug repro if you use 1.64.2 and then downgrade to C/C++ version 1.5.1 (or some version earlier than 1.8.4).

[lifw555]

downgrade to C/C++ version 1.7.1 (vscode 1.62.3) work fine.

[lifw555]

C/C++ version 1.8.4 (vscode 1.64.2) , i got the error in log(window):
