# Required packages:
# - musl-dev, musl-tools - the musl toolchain
# - curl, g++, make, pkgconf, cmake - for fetching and building third party libs
# - ca-certificates - openssl + curl + peer verification of downloads
# - xutils-dev - for openssl makedepend
# - libssl-dev and libpq-dev - for dynamic linking during diesel_codegen build process
# - git - cargo builds in user projects
# - linux-headers-amd64 - needed for building openssl 1.1 (stretch only)
# - file - needed by rustup.sh install
# - automake autoconf libtool - support crates building C deps as part cargo build
# NB: does not include cmake atm

# SSL cert directories get overridden by --prefix and --openssldir
# and they do not match the typical host configurations.
# The SSL_CERT_* vars fix this, but only when inside this container
# musl-compiled binary must point SSL at the correct certs (muslrust/issues/5) elsewhere
# Postgres bindings need vars so that diesel_codegen.so uses the GNU deps at build time
# but finally links with the static libpq.a at the end.
# It needs the non-musl pg_config to set this up with libpq-dev (depending on libssl-dev)
# See https://github.com/sgrif/pq-sys/pull/18
