# Tested on Debian GNU/Linux 11 (bullseye)
#
# * git: to get the Centipede sources.
# * bazel: to build Centipede.
# * libssl-dev: to link Centipede (it uses SHA1).
# * binutils: Centipede uses objdump.
# * clang: to build Centipede and the targets.
#   For most of the functionality clang 11 or newer will work.
#   To get all of the functionality you may need to install fresh clang from
#   source: https://llvm.org/.
#   The functionality currently requiring fresh clang from source:
#     * -fsanitize-coverage=trace-loads
#     (https://clang.llvm.org/docs/SanitizerCoverage.html#tracing-data-flow)

# Get Clang-14, the earliest version that supports dataflow tracing:
#   * Download Clang from Chromium to support old OS (e.g. Ubuntu 16).
