Fixes #212

What

Adds a GitHub Actions Release workflow (.github/workflows/release.yml) that builds self-contained, prebuilt SDK bundles and attaches them to a GitHub Release:

  • Triggered by every v* tag push, or on demand from the Actions tab (specify the target tag).
  • Matrix: linux-amd64, linux-arm64, macos-amd64, macos-arm64, windows-amd64 (GA hosted runners; arm64 uses ubuntu-24.04-arm / macos-latest).
  • Each bundle is one flat, relocatable prefix: miniocpp headers, all static libraries (miniocpp and its dependencies), CMake package configs and miniocpp.pc, produced by cmake --install into vcpkg's vcpkg_installed/<triplet> tree.
  • A release job creates (or updates, with --clobber) the release and uploads all bundles.

Users without vcpkg or a reliable network (the reporter of #212) can then simply:

curl -LO https://github.com/minio/minio-cpp/releases/download/v0.4.0/minio-cpp-v0.4.0-linux-arm64.tar.gz
tar -xzf minio-cpp-v0.4.0-linux-arm64.tar.gz
cmake -S . -B build -DCMAKE_PREFIX_PATH="$PWD/minio-cpp-0.4.0-linux-arm64"

No vcpkg, no network, no extra dependency install needed.

Also fixed: cmake --install produced an unusable tree

  • include/miniocpp/result.h is included by 4 public headers but was missing from MINIO_CPP_HEADERS, so it was never installed.
  • The vendored include/tl (tl::expected, used by error.h/result.h for C++17) was never installed.

Both are required for any consumer to compile against an installed SDK; validated end-to-end locally with a fresh CMake consumer project (configure → build → run against the bundle with only CMAKE_PREFIX_PATH, no vcpkg toolchain).

Validation

  • actionlint clean on the new workflow (also on existing workflows).
  • Bundle consumption validated locally: find_package(miniocpp) resolves OpenSSL, CURL/curlpp, inih, nlohmann_json, pugixml, ZLIB entirely from the bundle prefix.
  • Build steps mirror ci.yml, which already exercises both ubuntu-24.04 and ubuntu-24.04-arm on every push.

Note

Windows arm64 and RDMA-enabled bundles are intentionally out of scope for now (no GA vcpkg/runner combination for the former; the RDMA build is covered by ci-rdma.yml); the matrix makes both easy to add later.

Summary by CodeRabbit

  • New Features

    • Added downloadable prebuilt SDK bundles for Linux, macOS, and Windows on amd64 and arm64.
    • Releases can be created automatically from version tags or manually.
  • Documentation

    • Added instructions for downloading, extracting, and configuring prebuilt bundles.
    • Documented supported platforms, archive contents, and release options.
  • Improvements

    • SDK installations now include all required public headers and dependencies.
    • Improved package configuration for relocatable SDK installations.

Adds a Release workflow that builds self-contained SDK bundles (headers +
static libraries + CMake/pkg-config metadata) for linux/macOS/windows on
both x86_64 and arm64 and attaches them to a GitHub Release on every v*
tag push (or manual dispatch), so users without vcpkg or a reliable
network can consume the SDK via CMAKE_PREFIX_PATH alone.

Also fixes the install tree: include/miniocpp/result.h was missing from
MINIO_CPP_HEADERS and the vendored include/tl (tl::expected) was never
installed, so 'cmake --install' produced a tree that could not compile
consumers.

📝 Walkthrough

Walkthrough

The PR adds a GitHub Actions workflow that builds SDK bundles for Linux, macOS, and Windows on x86_64 and arm64. CMake installs required public and vendored headers. The pkg-config metadata becomes relocatable. README documents bundle use and release automation.

Changes

SDK release pipeline

Layer / File(s) Summary
Release targets and public install contents
.github/workflows/release.yml, CMakeLists.txt, README.md
The workflow defines tag and manual triggers for Linux, macOS, and Windows builds. CMake installs result.h and the vendored tl headers. README documents bundle contents and use.
SDK bundle build and packaging
.github/workflows/release.yml, miniocpp.pc.in
The workflow validates tags, installs pinned vcpkg and build tools, builds the SDK, installs it into a triplet-specific prefix, creates platform archives, and uploads them as artifacts. pkg-config paths use the installed .pc file location.
GitHub Release publication
.github/workflows/release.yml
The release job downloads build artifacts, verifies tag stability, and creates or updates the corresponding GitHub Release.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 8be39

The release workflow can resolve the requested tag inconsistently across build jobs, and publishing by tag may recreate a missing tag from the default branch, which could produce SDK bundles from unintended source code. The PR is mergeable with explicit owner awareness or follow-up on tag validation and consistency.

Builds arm64 packs in every bag.
Headers hop into the files,
Archives cross the build-run miles.
GitHub marks the bundle bright.

then grant contents: write only within the release job. In both build job
checkout steps, disable persisted checkout credentials while preserving the
existing checkout behavior.
- Around line 61-64: Update the “Checkout minio-cpp” actions/checkout step to
set its ref from inputs.tag for workflow_dispatch runs, while preserving the
existing checkout behavior for other trigger types so the checked-out source
matches the archive label.
- Around line 62-71: Pin all mutable dependencies in
.github/workflows/release.yml to the reviewed commit SHAs: update every
actions/checkout use to 11d5960a326750d5838078e36cf38b85af677262,
microsoft/vcpkg’s ref to 9e593bb18ea69cc5095e012465dcd675a822ed0d,

changes at the anchor site .github/workflows/release.yml lines 62-71 and sibling
site lines 141-162.
- Around line 55-58: Update the Windows release matrix entry in
.github/workflows/release.yml:55-58 to use x64-windows-static, and ensure the
vcpkg install command passes the matrix triplet and CMake receives
VCPKG_TARGET_TRIPLET from that same value. README.md:49-52 requires no direct
change because the workflow fix preserves its existing static-library and
dependency claims.

without interpolating the input into generated Bash source. Before checkout,
validate that the value matches an existing v-prefixed tag, rejecting invalid or
nonexistent tags before proceeding; use the validated TAG for checkout and
artifact handling.

- Keep inputs.tag out of shell source: pass it via env in both resolve steps
- Validate manual dispatch tags (v-prefixed and existing) before checkout
- Add a concurrency guard for the workflow
- Pin the macOS arm64 runner to macos-15 instead of macos-latest
- Make miniocpp.pc relocatable with a pcfiledir-relative prefix so the
  bundled .pc stays valid after extraction

- Pass steps.tag.outputs (archive/tag) via env in the Package and release
  steps instead of interpolating them into Bash, closing an injection path
  for tags containing shell metacharacters
- Validate step now resolves the manual-dispatch tag to its peeled commit
  SHA (annotated and lightweight tags), and the checkout builds that exact
  commit instead of re-resolving the tag by name (TOCTOU race)

invoke gh release create with tag verification enabled.

- New 'resolve' job validates the manual-dispatch tag (v-prefixed, no '/',
  exists), resolves it to its peeled commit SHA and exposes tag/sha as job
  outputs; all build jobs and the release job consume those shared values
  and checkout that exact commit
- Release job re-verifies the tag still points to the resolved SHA before
  publishing, and 'gh release create' now uses --verify-tag so a missing
  tag is never silently created from the default branch

The pre-publication tag check was gated on workflow_dispatch, leaving
tag-push releases without protection against the tag being moved while
the build ran. Run the ls-remote comparison for both trigger types.
