1. Reset coverage data: lcov -z 2. Run LTP (or any other test case) 3. Capture coverage data: lcov -c -o coverage.info 4. Generate HTML output: genhtml coverage.info -o out 5. View HTML output: <browser> out/index.html More information on lcov can be found on the page behind the second URL your quoted in your mail.
