error when c-cpp-flylint.language is set to C

[chenyulue]

I have set c-cpp-flylint.language to C language, there is alway an error reading:

vscode-c-cpp-flylint: 'Line could not be parsed: error: invalid argument '--std=c++11' not allowed with 'C'' while validating: c:\Users\xj\Exercism\c\sieve\sieve.c. Please analyze the 'C/C++ FlyLint' Output console. Stacktrace: Error: Line could not be parsed: error: invalid argument '--std=c++11' not allowed with 'C'

If I set c-cpp-flylint.language to C++ language, the above error disappears.

So how to cope with this error when c-cpp-flylint.language is set to C language?

Try to set c-cpp-flylint.standard to c11.

@jbenden Thanks! It works.

A new question: in my code, there are some Chinese characters. Therefore, the plugin gives vscode-c-cpp-flylint: 'Line could not be parsed: Error: encoding error in ... error. I guess this is related to the Chinese characters and the encoding. The text encoding of my vscode editor is utf-8. I haven't found any setting related to encoding.

Hi,

Would you please enable debugging (c-cpp-flylint.debug setting) and post the full log shown in the "C/C++ Flylint" output window? I am not sure where in the code it would give this error message. I believe I've specified "utf-8" encoding where possible...

Thanks,
-Joe

The full log shows Flawfinder gives the error. When I disable Flawfinder, the error disappears.

Hello,

A new extension was just published a minute ago. If you still experience this problem, then please capture a full debugging log and post it here. In the extension's settings you may enable debug and verbose.

I am hoping that UTF-8 pass-through will occur now...

Thanks,
