# CBLPolyCall - COBOL FFI Bridge for PolyCall

## Overview

CBLPolyCall is a comprehensive COBOL Foreign Function Interface (FFI) bridge for the PolyCall library, developed as part of the OBINexus Aegis Engineering project under the technical leadership of Nnamdi Michael Okpala. The system implements cost-dynamic function optimization and modular library architecture for enterprise-grade COBOL integration.

## Cost Dynamics & Performance Architecture

### Cost-Dynamic Function Analysis

CBLPolyCall implements intelligent cost-dynamic function optimization through multiple architectural layers:

#### 1. **Static Library Cost Model** (`libcblpolycall.a`)
- **Memory Footprint**: Minimal - embedded directly in executable
- **Runtime Overhead**: Zero dynamic loading cost
- **Distribution Cost**: Higher executable size, single deployment unit
- **Use Case**: Standalone applications, embedded systems

#### 2. **Shared Library Cost Model** (`libcblpolycall.dll/.so`)
- **Memory Footprint**: Shared across multiple processes
- **Runtime Overhead**: Dynamic loading cost at startup
- **Distribution Cost**: Separate library dependency management
- **Use Case**: Multiple applications sharing PolyCall functionality

#### 3. **Hybrid Cost Architecture**
- **Development Phase**: Use shared libraries for rapid iteration
- **Production Phase**: Static linking for deployment simplicity
- **Resource Optimization**: Library switching based on deployment constraints

### Library Architecture Components

```
CBLPolyCall Library Architecture
├── Static Libraries (.a)
│   ├── libcblpolycall.a          # Core FFI bridge
│   └── libpolycall-constants.a   # COBOL constants
├── Shared Libraries (.dll/.so)
│   ├── libcblpolycall.dll        # Dynamic FFI bridge
│   └── libpolycall-runtime.dll   # Runtime support
├── Executables
│   ├── cblpolycall.exe           # Library-linked executable
│   └── cblpolycall-standalone.exe # Self-contained executable
└── Configuration
    ├── default.conf              # GnuCOBOL configuration
    └── library.conf               # Library linkage configuration
```

## Installation & Build Architecture

### Prerequisites

#### Windows Environment
- **GnuCOBOL 3.2+** (Primary compiler)
- **Microsoft Visual C++ Build Tools** (Alternative)
- **Git for Windows** (Unix tools compatibility)
- **PowerShell 5.1+** (Build orchestration)

#### Library Dependencies
- **PolyCall Runtime**: `libpolycall.dll` or equivalent
- **C Runtime**: MSVCRT or compatible
- **Network Libraries**: Winsock2, ws2_32.lib

### Building with Program Libraries - Windows Protocol

#### Method 1: Windows Native Build System (Recommended)

```powershell
# Initialize project structure with library support
.\build.bat init

# Create comprehensive local configuration
.\build.bat config

# Build all library components
.\build.bat libraries

# Generate both shared and static libraries
.\build.bat shared    # Creates libcblpolycall.dll
.\build.bat static    # Creates libcblpolycall.a

# Build executable with library linkage
.\build.bat executable

# Alternative: Build standalone (no external libraries)
.\build.bat standalone

# Comprehensive build (all components)
.\build.bat all
```

#### Method 2: Cross-Platform Development (Git Bash/WSL)

For developers requiring Unix-compatible tooling:

```bash
# Using Git Bash with Unix tools
export PATH="/c/Program Files/Git/usr/bin:$PATH"
make debug    # Verify environment
make all      # Build with Unix compatibility

# Using Windows Subsystem for Linux (WSL)
wsl make all
```

### Optimization Strategies

1. **Static Linking**: Eliminates runtime loading overhead
2. **Shared Libraries**: Reduces memory footprint for multiple processes
3. **Lazy Loading**: Deferred library initialization
4. **Connection Pooling**: Amortized connection costs
5. **Batch Operations**: Reduced per-operation overhead

## Troubleshooting

### Common Build Issues

#### Issue: Unix Tools Not Found (Windows)
```
Solution: Use .\build.bat instead of make
Alternative: Install Git Bash or WSL
```

#### Issue: Library Linkage Failures
```
Solution: Verify libpolycall.dll availability
Check: .\build.bat debug for environment status
```

#### Issue: Configuration Conflicts
```
Solution: .\build.bat clean && .\build.bat config
Verify: config\default.conf readonly status
```
