# Usage(on repo root folder):
#   docker build . --pull --no-cache --shm-size=196m -t darkfi:riscv -f ./contrib/docker/riscv.Dockerfile -o riscv-bins
# Optionally, add arguments like: --build-arg BINS=darkirc
# If you want to keep building using the same builder, remove --no-cache option.

# Arguments configuration
ARG DEBIAN_VER=latest
ARG SQL_VER=3420000
ARG RUST_VER=nightly
#TODO: only darkirc has been tested, have to check rest binaries to add deps and ports.
ARG BINS=darkirc
# When changing riscv target, don't forget to also update the linker
ARG RISCV_TARGET=riscv64gc-unknown-linux-gnu
ARG RISCV_LINKER=riscv64-linux-gnu-gcc

# Environment setup
FROM debian:${DEBIAN_VER} as builder

## Arguments import
ARG SQL_VER
ARG RUST_VER
ARG RISCV_TARGET
ARG RISCV_LINKER
ARG BINS
