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

based on this post, the difference may depend on the version of gcc you are using. Can you share which versions you are using. I am not getting branch coverage on:

 i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
