# The ere-base image provides Rust, Cargo, and common tools.
# We operate as root for SDK installation.

# Define the Pico toolchain for convenience in subsequent commands if needed, though cargo pico should use it.
ENV PICO_TOOLCHAIN_VERSION="nightly-2025-08-04"

# Set default toolchain
RUN rustup default "$PICO_TOOLCHAIN_VERSION"

# Copy the Pico SDK installer script from the workspace context

# Run the Pico SDK installation script.
# This script installs the specific Rust toolchain (nightly-2025-08-04)
# and installs pico-cli (as cargo-pico).
# The CARGO_HOME from ere-base (e.g., /usr/local/cargo) will be used, and cargo-pico will be in its bin.
RUN /tmp/install_pico_sdk.sh && rm /tmp/install_pico_sdk.sh # Clean up the script

# Verify Pico installation
RUN echo "Verifying Pico installation in Dockerfile (post-script)..." && cargo pico --version
