@mhdawson do you remember why we're running gcovr from a branch and floating a patch? It would be nice to simplify this.

It been long enough that I don't remember the specifics. I assume it failed to run properly with out that patch. It's possible a later version of gcovr may have fixed it.

@mhdawson I've managed to get gcovr@4.2 working, installed directly from pip.

The trick was to continue running from the out/ folder, but to specify a --root pointing to the root project directory.
