darkfi/contrib/docker/riscv.Dockerfile

# This script uses QEMU emulation, so before execution pull the corresponding
# images:
#   docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

# Usage(on repo root folder):
#   docker build . --platform=linux/riscv64 --pull --no-cache --shm-size=196m -t darkfi:riscv -f ./contrib/docker/riscv2.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=sid
ARG RUST_VER=nightly-2025-04-10
#TODO: only darkirc has been tested, have to check rest binaries to add deps and ports.
ARG BINS=darkirc

# Environment setup
FROM --platform=$TARGETPLATFORM riscv64/debian:${DEBIAN_VER} as builder

## Arguments import
