# YAZE Build Guide
**Status**: CI/CD Overhaul Complete ✅
**Last Updated**: October 2025
**Platforms**: macOS (ARM64/Intel), Linux, Windows
## Quick Start
### macOS (Apple Silicon)
```bash
# Basic debug build
cmake --preset mac-dbg && cmake --build --preset mac-dbg
# With AI features (z3ed agent, gRPC, JSON)
cmake --preset mac-ai && cmake --build --preset mac-ai
# Release build
cmake --preset mac-rel && cmake --build --preset mac-rel
```
### Linux
```bash
# Debug build
cmake --preset lin-dbg && cmake --build --preset lin-dbg
# With AI features
cmake --preset lin-ai && cmake --build --preset lin-ai
```
### Windows (Visual Studio)
```bash
# Debug build
cmake --preset win-dbg && cmake --build --preset win-dbg
# With AI features
cmake --preset win-ai && cmake --build --preset win-ai
```
## Build System Overview
### CMake Presets
The project uses a streamlined preset system with short, memorable names:
| Preset | Platform | Features | Build Dir |
|--------|----------|----------|-----------|
| `mac-dbg`, `lin-dbg`, `win-dbg` | All | Basic debug builds | `build/` |
| `mac-ai`, `lin-ai`, `win-ai` | All | AI features (z3ed, gRPC, JSON) | `build_ai/` |
| `mac-rel`, `lin-rel`, `win-rel` | All | Release builds | `build/` |
| `mac-dev`, `win-dev` | Desktop | Development with ROM tests | `build/` |
| `mac-uni` | macOS | Universal binary (ARM64+x86_64) | `build/` |
Add `-v` suffix (e.g., `mac-dbg-v`) for verbose compiler warnings.
### Build Configuration
- **C++ Standard**: C++23 (required)
- **Generator**: Ninja Multi-Config (all platforms)
- **Dependencies**: Bundled via Git submodules or CMake FetchContent
- **Optional Features**:
- gRPC: Enable with `-DYAZE_WITH_GRPC=ON` (for GUI automation)
- AI Agent: Enable with `-DZ3ED_AI=ON` (requires JSON and gRPC)
- ROM Tests: Enable with `-DYAZE_ENABLE_ROM_TESTS=ON -DYAZE_TEST_ROM_PATH=/path/to/zelda3.sfc`
## CI/CD Build Fixes (October 2025)
### Issues Resolved
#### 1. CMake Integration ✅
**Problem**: Generator mismatch between `CMakePresets.json` and VSCode settings
**Fixes**:
- Updated `.vscode/settings.json` to use Ninja Multi-Config
- Fixed compile_commands.json path to `build/compile_commands.json`
- Created proper `.vscode/tasks.json` with preset-based tasks
- Updated `scripts/dev-setup.sh` for future setups
#### 2. gRPC Dependency ✅
**Problem**: CPM downloading but not building gRPC targets
**Fixes**:
- Fixed target aliasing for non-namespaced targets (grpc++ → grpc::grpc++)
- Exported `ABSL_TARGETS` for project-wide use
- Added `target_add_protobuf()` function for protobuf code generation
- Fixed protobuf generation paths and working directory
#### 3. Protobuf Code Generation ✅
**Problem**: `.pb.h` and `.grpc.pb.h` files weren't being generated
**Fixes**:
- Changed all `YAZE_WITH_GRPC``YAZE_ENABLE_GRPC` (compile definition vs CMake variable)
- Fixed variable scoping using `CACHE INTERNAL` for functions
- Set up proper include paths for generated files
- All proto files now generate successfully:
- `rom_service.proto`
- `canvas_automation.proto`
- `imgui_test_harness.proto`
- `emulator_service.proto`
#### 4. SDL2 Configuration ✅
**Problem**: SDL.h headers not found
**Fixes**:
- Changed all `SDL_TARGETS``YAZE_SDL2_TARGETS`
- Fixed variable export using `PARENT_SCOPE`
- Added Homebrew SDL2 include path (`/opt/homebrew/opt/sdl2/include/SDL2`)
- Fixed all library targets to link SDL2 properly
#### 5. ImGui Configuration ✅
**Problem**: Conflicting ImGui versions (bundled vs CPM download)
**Fixes**:
- Used bundled ImGui from `ext/imgui/` instead of downloading
- Created proper ImGui static library target
- Added `imgui_stdlib.cpp` for std::string support
- Exported with `PARENT_SCOPE`
#### 6. nlohmann_json Configuration ✅
**Problem**: JSON headers not found
**Fixes**:
- Created `cmake/dependencies/json.cmake`
- Set up bundled `ext/json/`
- Added include directories to all targets that need JSON
#### 7. GTest and GMock ✅
**Problem**: GMock was disabled but test targets required it
**Fixes**:
- Changed `BUILD_GMOCK OFF``BUILD_GMOCK ON` in testing.cmake
- Added verification for both gtest and gmock targets
- Linked all four testing libraries: gtest, gtest_main, gmock, gmock_main
- Built ImGuiTestEngine from bundled source for GUI test automation
### Build Statistics

## Test Execution
### Build Tests
```bash
# Build tests
cmake --build build --target yaze_test
# Run all tests
./build/bin/yaze_test
# Run specific categories
./build/bin/yaze_test --unit # Unit tests only
./build/bin/yaze_test --integration # Integration tests
./build/bin/yaze_test --e2e --show-gui # End-to-end GUI tests
# Run with ROM-dependent tests
./build/bin/yaze_test --rom-dependent --rom-path zelda3.sfc
# Run specific test by name
./build/bin/yaze_test "*Asar*"
```
### Using CTest
```bash
# Run all stable tests
ctest --preset stable --output-on-failure
# Run all tests
ctest --preset all --output-on-failure
# Run unit tests only
ctest --preset unit
# Run integration tests only
ctest --preset integration
```
## Platform-Specific Notes
### macOS
- Supports both Apple Silicon (ARM64) and Intel (x86_64)
- Use `mac-uni` preset for universal binaries
- Bundled Abseil used by default to avoid deployment target mismatches
- Requires Xcode Command Line Tools
**ARM64 Considerations**:
- gRPC v1.67.1 is the tested stable version
- Abseil SSE flags are handled automatically
- See docs/BUILD-TROUBLESHOOTING.md for gRPC ARM64 issues
### Windows
- Requires Visual Studio 2022 with "Desktop development with C++" workload
- Run `scripts\verify-build-environment.ps1` before building
- gRPC builds take 15-20 minutes first time (use vcpkg for faster builds)
- Watch for path length limits: Enable long paths with `git config --global core.longpaths true`
**vcpkg Integration**:
- Optional: Use `-DYAZE_USE_VCPKG_GRPC=ON` for pre-built packages
- Faster builds (~5-10 min vs 30-40 min)
- See docs/BUILD-TROUBLESHOOTING.md for vcpkg setup
### Linux
- Requires GCC 13+ or Clang 16+
- Install dependencies: `libgtk-3-dev`, `libdbus-1-dev`, `pkg-config`
- See `.github/workflows/ci.yml` for complete dependency list
## Build Verification
After a successful build, verify:
- ✅ CMake configuration completes successfully
-`compile_commands.json` generated (62,066 lines, 10,344 source files indexed)
- ✅ Main executable links successfully
- ✅ All test executables build successfully
- ✅ IntelliSense working with full codebase indexing
