Re: gcov trouble

Hi

In addition I have to mention that gcov -b file.cpp works if file.cpp DOES NOT
include any other .h files with using code from other parts of the project
except from including standard headers and using standard functions. So,
gcov can analyse the code used as basis for other parts of the project but not
the code in the top or in the middle of project hierarchy. Strange a bit.
Has anybody had the same experience?
