# Builder image Alpine 3.9
# gcc/g++ v 8
# golang v 1.12
# python 3.7
# nng library (libnng.so, libnng.so.X.X.X; see below for pinned version)
# Includes RIC libraries as a distribution path because
# PackageCloud does not support Alpine .apk (yet):
# mdc log library (libmdclog.so, libmdbclog.so.X.X.X; see below for pinned version)
# rmr library (librmr_nng.so, libmdclog.so..X.X.X; see below for pinned version)
# How to get a library file from this Docker base image:
# COPY --from=nexus3.o-ran-sc.org:10004/bldr-alpine3:1-a3.9 /usr/local/lib64/libnng.so.X.X.X /usr/local/lib
# COPY --from=nexus3.o-ran-sc.org:10004/bldr-alpine3:1-a3.9 /usr/local/lib64/librmr_nng.so.X.X.X /usr/local/lib
# COPY --from=nexus3.o-ran-sc.org:10004/bldr-alpine3:1-a3.9 /usr/local/lib/libmdclog.so.X.X.X /usr/local/lib
# Some packages install to /usr/local/lib, others to /usr/local/lib64
# Alpine by default searches /usr/local/lib but not /usr/local/lib64
