# Build And Compile

Build And Compile helps detect build systems, compile code, and resolve missing dependencies across languages. Use it when builds fail, libraries are missing, or link errors need fixing.

**Install:**

```bash
npx degit https://github.com/vstorm-co/pydantic-deepagents/tree/main/pydantic_deep/bundled_skills/build-and-compile ~/.claude/skills/build-and-compile
```

# Build & Compile

Strategies for building code and resolving dependency issues.

## Build System Detection

Check for build files in order:
- `Makefile` → `make` (read it first to understand targets)
- `CMakeLists.txt` → `cmake -B build && cmake --build build`
- `pyproject.toml` / `setup.py` → `pip install -e .`
- `package.json` → `npm install && npm run build`
- `Cargo.toml` → `cargo build --release`
- `go.mod` → `go build ./...`
- No build system → compile directly (`gcc`, `g++`, `rustc`, etc.)

## Compilation Strategies

### C/C++
- Always read the Makefile/CMakeLists first
- Common flags: `-O2 -Wall -lm -lpthread`
- Missing headers → `apt-get install lib<name>-dev`
- Linking errors → check library order (dependencies last: `-lfoo -lbar -lm`)

### Python
- Use virtual environments when possible
- `pip install -e .` for editable installs
- Missing modules → check `requirements.txt`, `pyproject.toml`
- Version conflicts → read the actual error, pin versions

### Multi-language projects
- Build dependencies first (C libraries before Python bindings)
- Check for Cython, SWIG, or FFI bridges
- Environment variables often needed: `LD_LIBRARY_PATH`, `PYTHONPATH`

## Dependency Resolution

1. Read the FULL error message — the missing dependency is usually named
2. Search for the package: `apt-cache search <name>`, `pip search <name>`
3. Install the minimum needed — don't install everything
4. If a package is unavailable, check for alternatives or build from source

## Common Build Failures

| Error | Likely Cause | Fix |
|-------|-------------|-----|
| `fatal error: foo.h: No such file` | Missing dev headers | `apt-get install libfoo-dev` |
| `undefined reference to` | Missing library at link time | Add `-lfoo` flag |
| `No module named 'foo'` | Missing Python package | `pip install foo` |
| `command not found: make` | Build tools missing | `apt-get install build-essential` |
| `version 'GLIBC_X.Y' not found` | Binary built for newer system | Rebuild from source |
