generating branch coverage data for lcov

Question

i\'m trying to use lcov for code coverage metrics, but I cannot get branches coverage to work.

Here\'s how i\'m using it:

g++ -ggdb3 --coverage src/read.         


        

Answer 1

The latest version of LCOV disabled branch coverage by default.

You need to re-enable it by either:

• editing your ~/.lcovrc file (copied from /etc/lcovrc) to change lcov_branch_coverage setting to 1
• adding --rc lcov_branch_coverage=1 to your lcov command lines
