I was trying to configure CodeCov on my GitHub repo with TravisCI. Since my repo is in C++ and I used CMake already, I essentially copy-pasted the after_success label of this example into my .travis.yml file:
after_success:
# Creating report
- cd ${TRAVIS_BUILD_DIR}
- lcov --directory . --capture --output-file coverage.info coverage info
- lcov --remove coverage.info '/usr/*' --output-file coverage.info
- lcov --list coverage.info
# Uploading report to CodeCov
- bash <(curl -s https://codecov.io/bash) || echo "Codecov did not collect coverage reports"
I pushed a custom .codecov.yml file to provide my token and notification settings, but the after_success is just the one suggested in the example. I'm really not familiar with lcov, so I have no idea whether something else is missing or what those calls are for.
Looking at CodeCov's documentation I couldn't find what I might be missing but my coverage reports are empty because lcov can't find some mysterious .gcda file (I guess). CodeCov's docs don't mention that anywhere so I guess I'm missing an important step in my configuration (or perhaps the file can't be found for some reason...?)
This is the output of TravisCI's after_success stage:
$ lcov --directory . --capture --output-file coverage.info
