# These are steps to compile ClamAV/ClamD on Amazon Linux 2 (could works also on other distro RHEL based)
# Needed because on arm platform, EPEL repositories has been deprecated and it's not possible anymore to
# install ClamAV in that WAY

# TO DO
# - Install or handle Rust, required for version 0.105
