I am trying to obtain code coverage for a component I am writing for the Arora browser, that is written using C++ and Qt framework.
I am not able to use the gcov pro
At least you should use
QMAKE_LFLAGS += -g -fprofile-arcs -ftest-coverage -O0
instead of
QMAKE_LDFLAGS += -g -fprofile-arcs -ftest-coverage -O0
I'm not sure if that will fix your problem but QMAKE_LDFLAGS is not going to do anything useful.
