unusedFunction false positive

[Andrea Cassioli]

Hi I have a project where several function are wrongly marked as unused. For instance in source/a/b/x.cpp

InputMetrics CalculateInputMetrics(const InputData& ds) {
// some code
}

then in another file source/a/y.cpp

void LogInputDataMetrics(const InputData& input_data) {
     auto metric = f(CalculateInputMetrics(input_data));
     // do stuff
}

CalculateInputMetrics is flagged as unused.

Sorry for late reply. hmm.. I don't get this false positive:

$ ~/.cppcheck/cppcheck-2.12.0 --enable=all a.cpp b.cpp
Checking a.cpp ...
1/2 files checked 35% done
Checking b.cpp ...
2/2 files checked 100% done
b.cpp:1:0: style: The function 'LogInputDataMetrics' is never used. [unusedFunction]
void LogInputDataMetrics(const InputData& input_data) {
^

do you use some similar cppcheck options?
