Troubleshooting Guide

Common Issues and Solutions

Installation Issues

NAAb Build Fails

Problem: cmake: command not found

Solution:

# Ubuntu/Debian
sudo apt-get install cmake build-essential

# macOS
brew install cmake

# Fedora
sudo dnf install cmake gcc-c++

Submodule Empty

Problem: naab/ directory exists but is empty

Solution:

cd naab-pivot
git submodule update --init --recursive
bash build.sh

Permission Denied

Problem: bash: ./naab/build/naab-lang: Permission denied

Solution:

chmod +x naab/build/naab-lang

Compilation Issues

Go Compiler Not Found

Problem: "Go compiler not found"

Solution:

# Install Go
# Ubuntu/Debian
sudo apt-get install golang-go

# macOS
brew install go

# Or download from https://go.dev/dl/

# Verify
go version

Rust Compiler Not Found

Problem: "rustc: command not found"

Solution:

# Install Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Verify
rustc --version

C++ Compilation Fails

Problem: "g++: error: unrecognized command line option '-march=native'"

Solution:

# Use generic optimization instead
./naab/build/naab-lang pivot.naab evolve slow.py --profile conservative

Validation Issues

Parity Validation Fails

Problem: "Parity NOT CERTIFIED - deviation too high"

Reasons:

  1. Floating-point precision differences

Solution: Increase tolerance

export PIVOT_TOLERANCE=0.01  # 1% tolerance
./naab/build/naab-lang pivot.naab validate slow.py vessel
  1. Non-deterministic behavior (random, time-based)

Solution: Seed random generators, use fixed timestamps

  1. Integer overflow handling

Solution: Use --profile ultra-safe for overflow checking

Test Cases Fail

Problem: All test cases fail with "Execution error"

Solution: Check vessel binary directly

# Run vessel manually
./vessels/compute_vessel 10000

# Check exit code
echo $?  # Should be 0

Performance Issues

Slow Analysis

Problem: Analysis takes >5 minutes

Solutions:

  1. Check NAAb build mode:
cd naab/build
cmake .. -DCMAKE_BUILD_TYPE=Release
make clean && make naab-lang -j4
  1. Split large files:

If file >1000 LOC, split into smaller modules

  1. Use hotspot-only mode:
./naab/build/naab-lang pivot.naab evolve --hotspot-only slow.py

Slow Compilation

Problem: Vessel compilation takes too long

Solutions:

  1. Enable parallel compilation:
./naab/build/naab-lang pivot.naab synthesize blueprint.json --parallel 8
  1. Use cache:
# Avoid --no-cache flag
# Cache is enabled by default
  1. Use ccache:
# Install ccache
sudo apt-get install ccache

# Use with C++
export CXX="ccache g++"

Lower Speedup Than Expected

Problem: Speedup is only 1.5x, expected 5x

Possible Causes:

  1. I/O-bound workload (file reads, network calls)

    • Speedup limited by I/O, not CPU

  2. Wrong profile (ultra-safe instead of aggressive)

Solution:

./naab/build/naab-lang pivot.naab evolve slow.py --profile aggressive
  1. Not enough iterations in benchmark

Solution:

./naab/build/naab-lang benchmark.naab vessels/ --iterations 1000

Governance Issues

Governance Violation

Problem: "Governance check failed: Network access not allowed"

Solution: Modify govern.json

{
  "capabilities": {
    "network": {"enabled": true}
  }
}

Or use override (caution):

./naab/build/naab-lang pivot.naab --governance-override evolve slow.py

Blocked Language

Problem: "Language 'python' not allowed by governance"

Solution: Add to allowed languages in govern.json

{
  "languages": {
    "allowed": ["python", "cpp", "rust", "go"]
  }
}

Dashboard Issues

Dashboard Won't Start

Problem: "Address already in use"

Solution: Change port

export PIVOT_DASHBOARD_PORT=3000
./naab/build/naab-lang dashboard.naab

Dashboard Shows No Data

Problem: Dashboard is empty

Solution: Verify workspace path

export PIVOT_WORKSPACE=/path/to/projects
./naab/build/naab-lang dashboard.naab

Docker Issues

Docker Build Fails

Problem: "Docker build failed: Out of disk space"

Solution: Clean Docker

docker system prune -a
docker build -t naab-pivot .

Container Can't Access Files

Problem: "Permission denied" in Docker container

Solution: Fix volume permissions

docker run -it --rm \
  -v $(pwd):/workspace \
  --user $(id -u):$(id -g) \
  naab-pivot

Plugin Issues

Plugin Not Found

Problem: "Plugin not found: ml_detector"

Solution: Check plugin path

ls -la plugins/analyzers/ml_detector.naab
# Ensure file exists

# Register with full path
plugin_loader.register_plugin(
    "/absolute/path/to/plugins/analyzers/ml_detector.naab",
    "analyzer"
)

Plugin Execution Fails

Problem: "Plugin execution failed: ..."

Solution: Test plugin directly

use ml_detector

main {
    let result = ml_detector.execute({
        "source": "test code",
        "language": "python"
    })

    io.write(json.stringify(result, true), "\n")
}

Error Messages

"UNSUPPORTED_LANGUAGE"

Cause: File extension not recognized

Solution: Use --language flag

./naab/build/naab-lang pivot.naab analyze script.txt --language python

"COMPILATION_ERROR"

Cause: Generated code doesn't compile

Solution: Inspect generated code

cat vessels/compute_GO.go

# Try compiling manually
go build vessels/compute_GO.go

"PARITY_FAILED"

Cause: Implementations produce different results

Solution: Increase test count and tolerance

./naab/build/naab-lang pivot.naab validate slow.py vessel \
  --test-count 10000 \
  --tolerance 0.01

"TIMEOUT"

Cause: Operation exceeded time limit

Solution: Increase timeout

export PIVOT_TIMEOUT=600  # 10 minutes
./naab/build/naab-lang pivot.naab evolve slow.py

Debugging Tips

Enable Verbose Logging

./naab/build/naab-lang pivot.naab --verbose evolve slow.py

Check Environment Variables

env | grep PIVOT

Inspect Generated Files

ls -lah vessels/
cat vessels/compute_GO.go
file vessels/compute_vessel

Manual Testing

# Test vessel manually
./vessels/compute_vessel 10000

# Time execution
time ./vessels/compute_vessel 10000000

Use Debugger

# GDB for C++
gdb vessels/compute_vessel

# Delve for Go
dlv exec vessels/compute_vessel
