Right now Codacy does not support configuration files for cppcheck. Instead, you will have to define which patterns you want running on your analysis using our UI. You can do it by going to your repo and clicking on the tab Code Patterns on the left. Here you can select cppcheck and configure the patterns that you want active.
Please let me know if you have any trouble configuring this.
Is any configuration planned? While I can certainly switch off the code pattern, or ignore it in certain circumstances (there’s a bunch of places where it’s actually showing a potential problem), it’s a bit of extra hunting when it appears. Also it’s not entirely clear how to stop ignoring an error on a particular line of code.
