Use MISRA rules from the GUI?

[Bassam Abdul-Baki]

Change the Misra path to not have spaces in it. It doesn't work with spaces.

[Georgiy Komarov]

I can't reproduce. cppcheck-gui (built from commit
6a19313 with Qt 5.15.2) handles paths with spaces without any errors on my Linux machine.

cppcheck-gui starts QProcess with the required command that can contains file path with spaces as arguments. Under the hood, on Windows, Qt processes arguments to add quotes to each one that contains space symbols.

So, I believe, all should work as expected. However, I don't have a Windows machine for the tests yet.

Am I missing anything in settings or the path.

should the directory don't have any spaces - like program Files has space in the name ?

[Shobana Devi Sampath]

C:/CppCheck/addons/MisraRules.txt - I'm using this path without spaces now. Still no luck :(

Should I have any compiler installed ?

int main()
{
char a[10];
a[10] = 0;
return 0;
}

I have just stored these lines of code with C extension and running to find the misra errors.
Thank you very much for your support.

Does cppcheck-gui runs the checks at all? Do you see any messages in Analysis log tab?

Have you tried to check the source file containing MISRA violations?
For example, this one:

int foo(int unused)
{
    return 19;
}

int main(int argc, char *argv[])
{
    ++*(int*)0;
    return foo(42);
}

Should I have any compiler installed ?

No, you don't need any compiler installed to run cppcheck.

All the check is enabled. I have tried the same code snippet. Kindly check the attachment.

[Georgiy Komarov]

Hmm, strange.
Do you have the MISRA addon enabled? You can check this on File -> Edit Project File... -> Addons tab.

[Shobana Devi Sampath]

Hi ,

I didn't create a project file. I was directly trying to analyse the C file. After I added created the project file and edited the addons tab, I'm able to see the misra warnings.

Thank you very much for your support.

how to support MISRA C 2012 Amendment1 additional security?

[Georgiy Komarov]

The MISRA addon doesn't support Amedment1 additional security rules.

But Cppcheck already has checks for some of the rules described in this document (see orbitcowboy's comment on your question on github).

So, answering your question, to support additional rules, they need to be implemented in MISRA addon. But you can find some violations using Cppcheck itself.

I'm just wondering, why do you need them for? As far as I know, if you want to certify your software (for example, for SIL compatibility), it is sufficient to use a set of rules from the MISRA document itself without any additions.

[Daniel Marjamäki]

For information, I can't promise anything but I do believe cppcheck and its addon will handle all MISRA C 2012 rules later this year, including the extra amendment rules.
