The fix: - Use **Zig's own C++ headers** (bundled libc++) — they work fine - Add **iOS SDK C headers** (`-isystem .../iPhoneOS26.2.sdk/usr/include`) for missing C types (`ldiv_t`, etc.) - Set `CMAKE_TRY_COMPILE_TARGET_TYPE=STATIC_LIBRARY` to skip CMake's link test (we only build static libs, never link executables) - Download iOS SDK via sparse git clone from [iOS-SDKs](https://github.com/xybp888/iOS-SDKs) No extra toolchains needed — just Zig + iOS SDK headers. ### Changes - **CMakePresets.json**: New `zig-arm64-ios` and `zig-arm64-ios-sim` presets - **scripts/download-ios-sdk.sh**: Downloads iOS SDK headers via sparse clone - **bootstrap.sh**: `build_ios` integrated into release parallel builds and CI_FULL validation (same infrastructure as macOS cross-compile) - **.gitignore**: Exclude `ios-sdk/` directory - **Removed**: `ios.toolchain.cmake` (1,135-line Xcode toolchain no longer needed) - **Removed**: Standalone `build-bb-ios` CI job from `ci3.yml` — iOS builds now run through `bootstrap.sh` on custom EC2 runners that already have Zig installed - **Removed**: `publish-bb-mac.yml` workflow (no longer need macOS runners) ### Tested locally - `cmake --preset zig-arm64-ios` — configures successfully - `cmake --build --target bb-external` — all 200 targets compile - `cargo build --target aarch64-apple-ios --features ffi` — barretenberg-rs builds against the static lib --- .github/workflows/ci3.yml | 43 - .github/workflows/publish-bb-mac.yml | 134 -- barretenberg/CLAUDE.md | 45 +- barretenberg/cpp/.gitignore | 1 + barretenberg/cpp/CMakePresets.json | 50 +- barretenberg/cpp/bootstrap.sh | 27 +- .../cpp/cmake/toolchains/ios.toolchain.cmake | 1135 ----------------- barretenberg/cpp/scripts/download-ios-sdk.sh | 37 + 8 files changed, 123 insertions(+), 1349 deletions(-) delete mode 100644 .github/workflows/publish-bb-mac.yml delete mode 100644 barretenberg/cpp/cmake/toolchains/ios.toolchain.cmake create mode 100755 barretenberg/cpp/scripts/download-ios-sdk.sh diff --git a/.github/workflows/ci3.yml b/.github/workflows/ci3.yml index fd40ccf7a063..ef8a644ff5c4 100644 --- a/.github/workflows/ci3.yml +++ b/.github/workflows/ci3.yml @@ -261,46 +261,3 @@ jobs: AWS_SHUTDOWN_TIME: 180 run: | ./.github/ci3.sh network-tests-kind - - # iOS cross-compilation build for barretenberg. - # Runs in parallel with the main CI job on every PR (~9 min per target). - # This builds the bb-external static library for iOS devices and simulators. - # Non-blocking (continue-on-error) to avoid rugging releases - alerts #honk-team on failure. - build-bb-ios: - name: Build iOS static libraries - runs-on: macos-14 - if: github.event.pull_request.head.repo.fork != true && github.event.pull_request.draft == false - continue-on-error: true - strategy: - fail-fast: false - matrix: - include: - - preset: ios-arm64 - label: arm64-ios - - preset: ios-sim-arm64 - label: arm64-ios-sim - steps: - - name: Checkout - uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683 - - - name: Create Build Environment - run: | - brew install cmake ninja - - - name: Compile bb-external for iOS - working-directory: barretenberg/cpp - run: | - cmake --preset ${{ matrix.preset }} - cmake --build --preset ${{ matrix.preset }} --target bb-external - - - name: Notify Slack on failure - if: failure() - env: - SLACK_BOT_TOKEN: ${{ secrets.SLACK_BOT_TOKEN }} - run: | - if [ -n "${SLACK_BOT_TOKEN}" ]; then - curl -X POST https://slack.com/api/chat.postMessage \ - -H "Authorization: Bearer $SLACK_BOT_TOKEN" \ - -H "Content-type: application/json" \ - --data "{\"channel\": \"#honk-team\", \"text\": \"iOS build (${{ matrix.preset }}) FAILED: \"}" - fi diff --git a/.github/workflows/publish-bb-mac.yml b/.github/workflows/publish-bb-mac.yml deleted file mode 100644 index df7935d4d4a3..000000000000 --- a/.github/workflows/publish-bb-mac.yml +++ /dev/null @@ -1,134 +0,0 @@ -name: Publish Barretenberg Mac - -on: - push: - tags: - - "v*" - workflow_dispatch: - # Allow pushing a manual nightly release - inputs: - ref_name: - description: The ref name to build as.
