git blame-like annotation of source files with gcov

I have successfully set up gcov in my project to generate HTML files with code coverage data using lcov. However, as I often work via SSH with a text console only, I'm looking for a way to generate annotated source files like git-blame does with the history:

covered     source_line();
not covered other_source_line();

Is it possible somehow?

I'm going to assume you are referring to gcovr when you say gcov, since gcov does not output to HTML format. gcovr does output to HTML though. gcovr is basically just a wrapper for gcov.

In order to get the annotated source files, you need to simply use gcov.

gcov, by default, annotates source files.

To run with gcov, you just need to compile with -fprofile-arcs -ftest-coverage -fPIC -O0, and link in the gcov library(-lgcov).

Then run your program.

Then issue the following command:

gcov main.c

Where main.c is whatever file you want your annotated analysis on.

After that, you will notice a new file created(main.c.gcov). This is the file you are looking for.

Here's a link on gcov usage
