Debugging Build Scripts

While developing your build script, it may be useful to run bash within the container:

$ python infra/helper.py shell $TARGET_NAME  # runs /bin/bash within container
$ compile                                   # run compilation manually

Debugging Fuzzers

If you decide to debug a fuzzer with gdb (which is already installed in libfuzzer-runner image), you will need to start a container in privileged mode:

docker run -ti --privileged -v /tmp/out:/out -t ossfuzz/libfuzzer-runner /out/some_fuzzer_name
