scripts/cpp-ref-key.sh names a harness/cpp/build.sh output (upstream commit plus a hash of CMakeLists.txt, build.sh, stubs/**, patches/**). The new cpp-reference workflow builds it on Ubuntu 24.04 and publishes it as GitHub Release cpp-ref-<key>; scripts/fetch-cpp.sh downloads and verifies it (curl, no token) or falls back to build.sh. CI's difftest job fetches instead of building and runs Rust and the cc-compiled shims through sccache.

# Package a finished harness/cpp/build.sh output for scripts/fetch-cpp.sh.

# Usage: scripts/package-cpp-ref.sh <cpp dir> <out dir>
|
|
#
|
|
# Writes <out dir>/solidcore-cpp-ref-<key>-linux-x86_64.tar.zst and a matching .sha256
|
|
# (sha256sum format), with <key> from scripts/cpp-ref-key.sh. The archive holds
|
|
# lib/libSMLib.a, lib/libSM_API.a, ffi.env, LICENSE (upstream Apache-2.0), NOTICE and
|
|
# BUILDINFO. ffi.env is relocatable as is: its paths are relative to the repository root
|
|
# (upstream/source/*/inc), which solidcore-ffi/build.rs resolves, and it has no absolute
|
|
# paths. compile_commands.json and the test apps are left out (absolute paths, not
|
|
# needed by solidcore-ffi). The libraries keep their -g debug info, as a source build.
|
|
# Run by .github/workflows/cpp-reference.yml.
