category:issue My C/C++ extension can not work

[XuMingxing]

My C/C++ extension can not work when I use vs code to editor a C file.
The outline shows "No symbols found in document xxx".
And when I pressed F12 or press ctrl+ left click , it always shows "no definition found for xxx".
I found the C/C+ extension runtime status has som uncaught errors: "Message header must separate key and value using: "

I need help.

Hi @XuMingxing . I don't believe there are any known issue that would be causing that behavior. The issue would seem to be related to your environment, configuration, and/or the source file involved. Could you provide more information, such as any settings related to the C/C++ extension, and example code that we might use to reproduce the issue?

I tried to reinstall sometimes, but the issue still exist. if you need debug, can you add some log in your codes and give me a patch, I will try to reproduce and send the log.

The VS Code team is suggesting you debug their JavaScript. It can be done via the Help->Toggle Developer Tools option.

I don't believe adding logging to our extension's code would help.

I think the only way to know what is going on is to set a breakpoing in the JavaScript code that is showing the "Message header" error.

I can't debug it myself because it doesn't repro for me. The error message in the developer console may have a link to the source file and you could set a breakpoint from there.

I can find the point of the error message in the source code, but I don't know how to debug it. the console log is below.

In the developer console, there should be a link on the error: workbench.desktop.main.js:formatted:285847 [[object Object]]Message header must separate key and value using : $onExtensionRuntimeError @ workbench.desktop.main.js:formatted:285847 workbench.desktop.main.js:formatted:285848 Error: Message header must separate key and value using : at ...\.vscode\extensions\ms-vscode.cpptools-1.7.1\dist\main.js:58801:23 that you can click to get to the javascript and you should be able to set a breakpoint on that line, then try to inspect the value json data to see why what value of the message header is that gives the error. There's some documentation at https://github.com/microsoft/vscode/wiki/How-to-Contribute#debugging (might be better documentation elsewhere).
