gcov is not generating coverage information for header files

Question

I\'m using gcov for the first time and I\'m having a problem which is similar to the one reported in this thread. However, I wasn\'t able to solve my problem following the comme

Answer 1

I want to complete the answer that I gave to @Klaus.

Both combinations "-O2 -g" and "-O2" gives the following coverage information for this method (I inserted the message only to be sure that the method was being executed in the tests):

-:  192:  const QString& institutionId(void) const {
1:  193:    std::cout << "Inside institutionId\n";
-:  194:    return m_institution;
-:  195:  }

That means that the lines 192 and 194 are not considered as executable, but only the cout. The flag -g does not affect the result (at least in this case).

If I build the program using "-O0", the result is:

1:  192:  const QString& institutionId(void) const {
1:  193:    std::cout << "Inside institutionId\n";
1:  194:    return m_institution;
-:  195:  }
