PC-Lint Messages not able to generate in "Problem" Column

[Vishal-Gaikwad]

I have sample C++ program with memory leak issue to detect. I am unable to see PC-Lint Plus error messages in "PROBLEM" window of VSCode but able to see the output messages on "OUTPUT" window.

Here is the configuration setting i am using:

{
    "window.zoomLevel": 1,
    "c-cpp-flylint.debug": true,
    "c-cpp-flylint.language": "c++",
    "c-cpp-flylint.clang.blocks": false,
    "c-cpp-flylint.clang.enable": false,
    "c-cpp-flylint.lizard.enable": false,
    "c-cpp-flylint.flexelint.enable": false,
    "c-cpp-flylint.flawfinder.enable": false,
    "c-cpp-flylint.cppcheck.enable": true,
    "c-cpp-flylint.pclintplus.enable": true,
    "c-cpp-flylint.pclintplus.executable": "D:\\PC-Lint\\windows\\pclp64.exe",
    "c-cpp-flylint.pclintplus.configFile": "D:\\PC-Lint\\windows\\lnt\\linter.lnt",
    "c-cpp-flylint.pclintplus.severityLevels": {
        "error": "Error",
        "warning": "Warning",
        "info": "Information",
        "note": "Hint"
      }
}

The error i am getting is as below: vscode-c-cpp-flylint: 'The diagnostic code undefined was neither a number nor string!' while validating: d:\SonarQube\Linter\VSCode\FirstProgram\HelloWorld.cpp. Please analyze the 'C/C++ FlyLint' Output console.

Could anyone please guide me what's the issue here?

I have the same problem, has your problem been solved?

Hello!

I also have this problem right now.

Here is my setup:

• VSCode 1.85.2
• FlyLint 1.13.1
• PClint Plus 1.4.1 on a windows machine

The error message in VSCode:

'The diagnostic code undefined was neither a number nor string!' while validating: c:\Users\[<user_home>]\[<path_to_source>]\test.c. Please analyze the 'C/C++ FlyLint' Output console. Stacktrace: TypeError: The diagnostic code undefined was neither a number nor string!

    at B (c:\Users\[<user_home>]\.vscode\extensions\jbenden.c-cpp-flylint-1.13.1\server\out\server.js:2:21800)

And the output of the debug window:

c:\Users\[<user_home>]\[<path_to_source>]\test.c is currently version number 34 and 28 was already been scanned.
c:\Users\[<user_home>]\[<path_to_source>]\test.c force = false.

Skipping scan of c:\Users\[<user_home>]\[<path_to_source>]\test.c because this file version number 34 has already been scanned.

This is my configuration of FlyLint in VSCode settings:

{
    "c-cpp-flylint.clang.enable": false,
    "c-cpp-flylint.cppcheck.enable": false,
    "c-cpp-flylint.flexelint.enable": false,
    "c-cpp-flylint.lizard.enable": false,
    "c-cpp-flylint.flawfinder.enable": false,
    "c-cpp-flylint.pclintplus.enable": true,
    "c-cpp-flylint.pclintplus.executable": "pclp64",
    "c-cpp-flylint.debug": true,
    "c-cpp-flylint.language": "c",
    "c-cpp-flylint.standard": [
        "c99"
    ],
    "c-cpp-flylint.includePaths": [
        ".",
        "./zlib",
        "./popt"
    ],
    "c-cpp-flylint.defines": [
        "NDEBUG",
        "HAVE_CONFIG_H"
    ],
    "c-cpp-flylint.run": "onType"
}

Can someone give me a hint, how this issue can be solved?

[xsp1989]

My problem has been solved and I submitted a PR, but the latest version hasn't been released yet and I'm not sure ours is the same problem. Here is the link where I submitted the PR:

https://github.com/jbenden/vscode-c-cpp-flylint/pull/212

Be sure there are no spaces in filenames; as that will cause problems. Shy of that, I do not have a license for the software to run testing with. Therefore, someone with one will need to triage this bug report.
