# 1. Import cross-compilation helpers

# ---------- Builder ----------
FROM --platform=$BUILDPLATFORM rust:1-bookworm AS builder

# Copy xx scripts
COPY --from=xx / /

# 2. Install NATIVE build tools (Runs on x86_64)
# We need clang (compiler), lld (linker), and pkg-config (to find libs).

# 3. Install TARGET architecture libraries
# - libssl-dev: required for openssl-sys
# - libc6-dev: required for C headers (fixes 'bits/libc-header-start.h' error)
# - libgcc-12-dev: required for C runtime files like crtbeginS.o (fixes linker errors)
# Note: We install 'libgcc-12-dev' specifically instead of 'gcc' to avoid
# pulling in the full compiler which caused header conflicts in earlier attempts.
