I am ramping up a Platform IO project. Within there I am using clang-tidy for different checks (see documentation for PIO clang-tidy here).
Given the folder structure
- .
-- include
-- src
I placed a header file in the include folder, called ISomeInterface.h The content looks like this:
#pragma once
namespace some_namespace { // interface declaration
}
When I run pio check (invokes clang-tidy) I get the warning
variable 'some_namespace' is non-const and globally accessible, consider making it const [cppcoreguidelines-avoid-non-const-global-variables]
The Question is: Why is CLang not recognizing the namespace keyword? I found a possible solution here SO Thread that states
can't use clang-tidy directly on header files. Instead i have to check the cpp file and have to add -header-filter=.* to also check the headers
But this did not work for me :(
