# Installs libraries and builds E2 manager
# Prerequisites:
#   Debian distro; e.g., Ubuntu
#   cmake (version?)
#   gcc/g++ compiler (version?)
#   golang (go), tested with version 1.12.0
#   current working directory is E2Manager
#   running with sudo privs, which is default in Docker

# TODO:
# 1) drop go from $PATH when build minion is extended
# 2) drop rewrite of path prefix when SonarScanner is extended

# Stop at first error and be verbose

# clobberfree=1 causes the garbage collector to clobber the memory content of an object with bad content when it frees the object.
# gcstoptheworld=1 disables concurrent garbage collection, making every garbage collection a stop-the-world event.
# Setting gcstoptheworld=2 also disables concurrent sweeping after the garbage collection finishes.
# Setting allocfreetrace=1 causes every allocation to be profiled and a stack trace printed on each object's allocation and free.
