#
# This Dockerfile for AFLplusplus uses Ubuntu 22.04 jammy and
# installs LLVM 14 for afl-clang-lto support.
#
# GCC 11 is used instead of 12 because genhtml for afl-cov doesn't like it.
#

LABEL "maintainer"="AFL++ team <afl@aflplus.plus>"
LABEL "about"="AFLplusplus container image"

### Comment out to enable these features
# Only available on specific ARM64 boards
ENV NO_CORESIGHT=1
# Possible but unlikely in a docker container
ENV NO_NYX=1

### Only change these if you know what you are doing:
# Current recommended LLVM version is 16
ENV LLVM_VERSION=16
# GCC 12 is producing compile errors for some targets so we stay at GCC 11
ENV GCC_VERSION=11

### No changes beyond the point unless you know what you are doing :)
