If you have already built your object files it may be necessary to run make clean first, or to find some other way to ensure that they get rebuilt with the options gcov requires.

Now the code coverage data has been collected "gcov" needs to be run:

 gcov Mylib.xs

This will create one or more gcov files on which you can run "gcov2perl":

 gcov2perl Mylib.xs.gcov

Finally, "cover" should be run as usual with any options required:

 cover

If you are running everything with standard options, you can do all this with one command:

 cover -test

 0   All files converted successfully
 >0  An error occurred.
