# GLIBC Compatibility Issue

## Problem

The Calimero `merod` binary in the Docker image requires newer versions of GLIBC than what's available in the container environment:

```
/usr/local/bin/merod: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.38' not found
/usr/local/bin/merod: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found
```

## Current Status

✅ **CLI is working correctly** - All commands function properly:
- `python3 merobox_cli.py run` - Attempts to start nodes (fails due to GLIBC)
- `python3 merobox_cli.py list` - Lists running nodes
- `python3 merobox_cli.py stop <node>` - Stops specific nodes
- `python3 merobox_cli.py logs <node>` - Shows node logs

✅ **Error handling is working** - CLI detects GLIBC issues and provides helpful error messages

## Solutions

### Option 1: Use a Different Base Image
Try using a different Docker image that's compatible with your system:

```bash
# Try with a different tag
python3 merobox_cli.py run --image ghcr.io/calimero-network/merod:6a47604

# Or use a different base image entirely
python3 merobox_cli.py run --image ubuntu:22.04
```

### Option 2: Build from Source
Build the Calimero binary from source in a compatible environment:

```bash
# Clone the Calimero repository
git clone https://github.com/calimero-network/core.git
cd core

# Build the binary
# (Follow Calimero's build instructions)

# Create a custom Docker image with the built binary
```

### Option 3: Use a Compatible Docker Base
Create a custom Dockerfile that uses a compatible base image:

```dockerfile
FROM ubuntu:22.04

# Install dependencies
RUN apt-get update && apt-get install -y \
    curl \
    wget \
    && rm -rf /var/lib/apt/lists/*

# Copy your built merod binary
COPY merod /usr/local/bin/merod

# Set up entry point
ENTRYPOINT ["/usr/local/bin/merod"]
```

### Option 4: Contact Calimero Team
The issue might be with the Docker image itself. Consider:
- Opening an issue on the [Calimero Network repository](https://github.com/calimero-network/core)
- Checking if there are alternative Docker images available
- Requesting a compatible image build

## Testing the CLI

Even with the GLIBC issue, you can test the CLI functionality:

```bash
# Test help
python3 merobox_cli.py --help
python3 merobox_cli.py run --help

# Test listing (will show no nodes)
python3 merobox_cli.py list

# Test with a working image (if available)
python3 merobox_cli.py run --image ubuntu:22.04
```

## Next Steps

1. **Try different image tags** from the Calimero repository
2. **Check for alternative images** in the Calimero ecosystem
3. **Build from source** if you need the exact functionality
4. **Use a compatible base image** and install Calimero manually

The CLI infrastructure is solid and ready to work once the GLIBC compatibility issue is resolved!
