## Build Configuration

### Active Build Groups
```bash
export BUILD_GROUP1=ON   # AP4: DDS middleware
export BUILD_GROUP3=ON   # AP3: Shared libraries (52 targets)
export BUILD_GROUP5=ON   # AP9: Viewer tools
export BUILD_GROUP6=ON   # AP9: Generators and toolchain
```

### Disabled Build Groups
```bash
BUILD_GROUP2=OFF   # Excluded from Release 2
BUILD_GROUP4=OFF   # Excluded from Release 2

BUILD_GROUP10=OFF  # Excluded from Release 2
BUILD_GROUP11=OFF  # Excluded from Release 2
BUILD_GROUP12=OFF  # Excluded from Release 2
```

## Key Changes from Original Build

### 1. Script Fixes (new_docker_build_release2.sh)
- **Fixed variable passing bug:** Removed extra quotes around `${BUILD_GROUP*}` variables
  - Before: `'"${BUILD_GROUP1}"'` (passed literal string `"'ON'"`)
  - After: `"${BUILD_GROUP1}"` (passes value `ON`)
- **Added Docker environment exports:** `-e BUILD_GROUP1`, `-e BUILD_GROUP3`, `-e BUILD_GROUP5`, `-e BUILD_GROUP6`

### 2. Core Library Additions
- **LtsCoordinate/LtsCoordTrans:** Uncommented in `Lts/Common/CMakeLists.txt`
  - Required by svcAesCommon → Trajectory → LtsCoordTrans → LtsCoordinate chain
- **LtsElevation:** Added to GROUP3_TARGETS
  - Required by Trajectory generator for elevation data

### 3. Conditional Dependencies
- **svcAesCommon (AreaEffectSimulation):** Made external dependencies conditional
  - `situationMapElevationMap` and `Trajectory` now use `TARGET_EXISTS` generator
  - Pattern: `$<IF:$<TARGET_EXISTS:target>,target,>`

### 4. Target Filtering
- **Original GROUP3_TARGETS:** 178 targets
- **Filtered GROUP3_TARGETS:** 52 targets (removed 126 excluded modules)
- **Removal criteria:**
  - Modules explicitly listed as "Excluded from Release 2" in CMakeLists.txt comments
  - Modules with hard `#include` dependencies on excluded components
  - Modules requiring unavailable build flags (BUILD_RTI, BUILD_GRANTLEE)

### 5. Removed Targets
**svcAlm* (AlarmManagement):** Removed due to missing code generation dependencies
- svcAlmClient, svcAlmCommon, svcAlmServer
- Require BUILD_RTI and BUILD_GRANTLEE flags not available in Release 2

**svcAreaEffectSimulation:** Removed due to hard dependency on excluded CentralEffectSimulation
- Contains `#include "CentralEffectSimulation/ces_ftc.h"` (non-conditional)
- Simpler to exclude than to refactor dependency

### DEB Package Build Pipeline

Based on `./external-dependencies/deb-packages/`:

```bash
# Build all Release 2 DEB packages
cd external-dependencies/deb-packages
./build-all-packages.sh --release2

# Output location
external-dependencies/deb-packages/output/
├── guez-release2-core_2.0.0_amd64.deb
├── guez-release2-dds_2.0.0_amd64.deb
├── guez-release2-tools_2.0.0_amd64.deb
└── guez-release2-dev_2.0.0_amd64.deb
```

### APT Repository Configuration

For installation on target systems:

```bash
# Add internal repository
echo "deb http://remote-repo.sl.defence-elec.de:8081/repository/ubuntu noble main" \
  | sudo tee /etc/apt/sources.list.d/guez.list

# Add signing key
wget -qO - http://10.198.80.75/rme/deb_and_rpm_signage_key.pub | sudo apt-key add -

# Install Release 2
sudo apt update
sudo apt install guez-release2-core guez-release2-dds guez-release2-tools
```

### Air-Gapped Deployment

For air-gapped environments:

```bash
# On internet-connected machine
cd external-dependencies/scripts
./download-deb-packages.sh /media/secure-usb/offline-cache

# Transfer to air-gapped machine via secure media
# On air-gapped machine
sudo dpkg -i /offline-cache/deb/*.deb
sudo apt install -f  # Resolve dependencies
```

### SBOM Requirements

Each DEB package must include:
- CycloneDX 1.6 SBOM (guez-release2-*-sbom.json)
- SLSA v1.0 provenance (guez-release2-*-provenance.json)
- License compliance report (guez-release2-*-licenses.txt)

Generated automatically by Jenkins pipeline in `external-dependencies/deb-packages/Jenkinsfile`.

---

## Next Steps

### Immediate
- [x] Validate Release 2 build scope (COMPLETED)
- [ ] Create DEB package manifests based on external-dependencies analysis
- [ ] Document installation dependencies for each package

### Future Releases
- **Release 3:** Reintroduce excluded modules with resolved dependencies
- **Release 4:** Add AlarmManagement with BUILD_RTI/GRANTLEE support
- **Release 5:** Add CentralEffectSimulation and dependent modules

---

## Technical Notes

### Dependency Chains
```
svcAesClient → svcAesCommon → LtsCoordTrans → LtsCoordinate
svcAesCommon → Trajectory → LtsElevation
```

### Build Script Pattern
```bash
cmake -G Ninja \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX=/opt/guez \
  -DBUILD_GROUP1=ON \
  -DBUILD_GROUP3=ON \
  -DBUILD_GROUP5=ON \
  -DBUILD_GROUP6=ON \
  ..
cmake --build . --target <TARGET_LIST>
```

### Known Warnings (Non-Fatal)
```
CMake Warning: Path referenced but not found:
  - /path/to/excluded/module/include (expected for optional dependencies)
```
