Keep getting gcov error when trying to run lcov in Windows command line

Question

I was wondering what else is actually needed in order to run lcov in windows command line? Every time when I run perl lcov, I always get a reminder or errors similar to the following:

geninfo: ERROR: need tool gcov!

I looked into my bin directory, and couldn't find a gcov.exe.

I normally do perl genhtml filename to get a html test coverage report of my javascript. I was trying to see if I can do perl lcov as I might want to combine several lcov files into one (and get the total test coverage).

Thanks.

It sure does look like you need gcov, doesn't it!

(For cygwin, it looks to be part of the gcc4-core package.)
