BS-42e6.gcno file debug

I am trying to configure gcov with existing code base for code coverage.The existing code base is service based code base (.i.e contain multiple file c and cpp with one service)

I have gone following wiki page for configure gcov and added -fprofile-arcs -ftest-coverage into makefile. When I compile the service it generate only one gcno file which some name (BS-42e6.gcno).

As per wiki page,gcov should generate gcno file for each c and cpp file like test.c.gcno and test1.cpp.gcno but I got one gcno file.

I could not figure out how will I proceed further with gcno file.

This service is exist in xml based framework.So we pass input from xml and framework do the marshalling and unmarshanlling for input parameter and pass c or cpp file.

So I have query about the testing gcov file.As per the wiki pages we got a.out from compilation and we run a.out and generate respective file. But In my case How Will I proceed further.

Please let me know if I need to provide more info

After a long debug,I found the issue When we pass gcov argument(-fprofile-arcs -ftest-coverage) during compile time.When I pass these argument during linking time I was able to generate successfully gcno file. just for reference for other
