There are some issues running the script from circle.yml, but more fundamental is this error that I get when trying to run individual commands on the CircleCI server:

No idea how to fix this!

gcov/lcov are installed via sudo apt-get install lcov. Maybe that should be done differently.

Tried setting CFLAGS/CXXFLAGS/LDFLAGS to make sure these flags propagate to all components of superbuild, but it didn't help.

The problem was caused by a mismatch in the version of compiler and gcov.

The solution is to use the matching version of gcov while running lcov: --gcov-tool /usr/bin/gcov-4.9
