I had a look at the -o option, but I'm not sure how to use it. For example, this is the only way I can get gcov to run: $ gcov tests/tests.cpp -o tests/tests-tests But then it produces tests.cpp.gcov that contains a bunch of lines like this: -: 1:/*EOF*/ -: 2:/*EOF*/ -: 3:/*EOF*/ -: 4:/*EOF*/ -: 5:/*EOF*/ -: 6:/*EOF*/ -: 7:/*EOF*/ -: 8:/*EOF*/ I'm also a bit confused about why I should supply a .cpp filename instead of a program name. How does it know which program to run? If I run "gcov string.cpp" how does gcov know that it needs to run some other program with certain parameters to actually execute the code in that file? Thanks, Adam.
