# Z3 Theorem Prover Development Guide
|
||||||
|
|
||||||
|
Always reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the info here.
|
||||||
|
|
||||||
|
## Working Effectively
|
||||||
|
|
||||||
|
### Bootstrap and Build the Repository
|
||||||
|
|
||||||
|
Z3 supports multiple build systems. **ALWAYS** use one of these validated approaches:
|
||||||
|
|
||||||
|
#### Option 1: Python Build System (Recommended for most use cases)
|
||||||
|
- `python scripts/mk_make.py` -- takes 7 seconds to configure
|
||||||
|
- `cd build && make -j$(nproc)` -- takes 15 minutes to complete. **NEVER CANCEL**. Set timeout to 30+ minutes.
|
||||||
|
|
||||||
|
#### Option 2: CMake Build System (Recommended for integration)
|
||||||
|
- Clean source tree first if you previously used Python build: `git clean -fx src/`
|
||||||
|
- `mkdir build && cd build`
|
||||||
|
- `cmake ..` -- takes 1 second to configure
|
||||||
|
- `make -j$(nproc)` -- takes 17 minutes to complete. **NEVER CANCEL**. Set timeout to 30+ minutes.
|
||||||
|
|
||||||
|
#### Dependencies and Requirements
|
||||||
|
- Python 3.x (required for both build systems)
|
||||||
|
- C++20 capable compiler (g++ or clang++)
|
||||||
|
- GNU Make
|
||||||
|
- Git (for version information)
|
||||||
|
|
||||||
|
### Test the Repository
|
||||||
|
|
||||||
|
**Python Build System:**
|
||||||
|
- Build unit tests: `make test` -- takes 3.5 minutes to compile. **NEVER CANCEL**. Set timeout to 10+ minutes.
|
||||||
|
- Run unit tests: `./test-z3 /a` -- takes 16 seconds. **NEVER CANCEL**. Set timeout to 5+ minutes.
|
||||||
|
|
||||||
|
**CMake Build System:**
|
||||||
|
- Build unit tests: `make test-z3` -- takes 4 minutes to compile. **NEVER CANCEL**. Set timeout to 10+ minutes.
|
||||||
|
- Run unit tests: `./test-z3 /a` -- takes 16 seconds. **NEVER CANCEL**. Set timeout to 5+ minutes.
|
||||||
|
|
||||||
|
**Test basic Z3 functionality:**
|
||||||
|
```bash
|
||||||
|
./z3 --version
|
||||||
|
echo "(declare-const x Int)(assert (> x 0))(check-sat)(get-model)" | ./z3 -in
|
||||||
|
```
|
||||||
|
|
||||||
|
### Validation Scenarios
|
||||||
|
|
||||||
|
**ALWAYS** test these scenarios after making changes:
|
||||||
|
|
||||||
|
#### Basic SMT Solving
|
||||||
|
```bash
|
||||||
|
cd build
|
||||||
|
echo "(declare-const x Int)
|
||||||
|
(assert (> x 0))
|
||||||
|
(check-sat)
|
||||||
|
(get-model)" | ./z3 -in
|
||||||
|
```
|
||||||
|
Expected output: `sat` followed by a model showing `x = 1` or similar.
|
||||||
|
|
||||||
|
#### Python Bindings
|
||||||
|
```bash
|
||||||
|
cd build/python
|
||||||
|
python3 -c "import z3; x = z3.Int('x'); s = z3.Solver(); s.add(x > 0); print('Result:', s.check()); print('Model:', s.model())"
|
||||||
|
```
|
||||||
|
Expected output: `Result: sat` and `Model: [x = 1]` or similar.
|
||||||
|
|
||||||
|
#### Command Line Help
|
||||||
|
```bash
|
||||||
|
./z3 --help | head -10
|
||||||
|
```
|
||||||
|
Should display version and usage information.
|
||||||
|
|
||||||
|
## Build System Details
|
||||||
|
|
||||||
|
### Python Build System
|
||||||
|
- Configuration: `python scripts/mk_make.py` (7 seconds)
|
||||||
|
- Main build: `cd build && make -j$(nproc)` (15 minutes)
|
||||||
|
- Test build: `make test` (3.5 minutes)
|
||||||
|
- Generates build files in `build/` directory
|
||||||
|
- Creates Python bindings in `build/python/`
|
||||||
|
- **Warning**: Generates files in source tree that must be cleaned before using CMake
|
||||||
|
|
||||||
|
### CMake Build System
|
||||||
|
- Clean first: `git clean -fx src/` (if switching from Python build)
|
||||||
|
- Configuration: `cmake ..` (1 second)
|
||||||
|
- Main build: `make -j$(nproc)` (17 minutes)
|
||||||
|
- **Advantages**: Clean build tree, no source pollution, better for integration
|
||||||
|
- **Recommended for**: IDE integration, package management, deployment
|
||||||
|
|
||||||
|
### Critical Timing and Timeout Requirements
|
||||||
|
|
||||||
|
**NEVER CANCEL these operations**:
|
||||||
|
- `make -j$(nproc)` builds: 15-17 minutes. **Set timeout to 30+ minutes minimum**.
|
||||||
|
- `make test` or `make test-z3` compilation: 3.5-4 minutes. **Set timeout to 10+ minutes**.
|
||||||
|
- Unit test execution: 16 seconds. **Set timeout to 5+ minutes**.
|
||||||
|
|
||||||
|
**Always wait for completion**. Z3 is a complex theorem prover with extensive code generation and builds may appear to hang but are actually progressing.
|
||||||
|
|
||||||
|
## Repository Structure
|
||||||
|
|
||||||
|

|
||||||
|
- `scripts/` - Build scripts and utilities

||||||
|
- `.github/workflows/` - CI/CD pipeline definitions
|
||||||
|
- `cmake/` - CMake configuration files
|
||||||
|
|
||||||
|
### Important Files

||||||
|
- `README.md` - Main documentation and build instructions
|
||||||
|
- `README-CMake.md` - Detailed CMake build documentation
|
||||||
|

|
||||||
|

||||||
|
2. **Run unit tests**: `./test-z3 /a` must pass
|
||||||
|
3. **Test basic functionality**: Run validation scenarios above
|
||||||
|
4. **Test affected language bindings**: If modifying API, test relevant examples
|
||||||
|
|
||||||
|
### Working with Language Bindings
|
||||||
|
- **Python**: Located in `build/python/`, test with validation scenario above
|
||||||
|
- **C/C++**: Examples in `examples/c/` and `examples/c++/`
|
||||||
|
- Compile C++ example: `g++ -I src/api -I src/api/c++ examples/c++/example.cpp -L build -lz3 -o test_example`
|
||||||
|
- Run with: `LD_LIBRARY_PATH=build ./test_example`
|
||||||
|
- **Java**: Build with `python scripts/mk_make.py --java`, examples in `examples/java/`
|
||||||
|
- **C#/.NET**: Build with `python scripts/mk_make.py --dotnet`, examples in `examples/dotnet/`
|
||||||
|
|
||||||
|
### Performance Testing
|
||||||
|
For performance-sensitive changes:
|
||||||
|
- Build optimized: `python scripts/mk_make.py` (Release mode by default)
|
||||||
|
- Test with realistic SMT problems from `examples/SMT-LIB2/`
|
||||||
|
- Use Z3's built-in statistics: `z3 -st problem.smt2`
|
||||||
|
|
||||||
|
## Common Issues and Solutions
|
||||||
|
|
||||||
|
### Build System Conflicts
|
||||||
|
- **Error**: CMake complains about polluted source tree
|
||||||
|
- **Solution**: Run `git clean -fx src/` to remove Python build artifacts
|
||||||
|
|
||||||
|
### Python Import Errors
|
||||||
|
- **Error**: `import z3` fails
|
||||||
|
- **Solution**: Ensure you're in `build/python/` directory or add it to `PYTHONPATH`
|
||||||
|
|
||||||
|
### Missing Dependencies
|
||||||
|
- **Error**: Compiler not found or version too old
|
||||||
|
- **Solution**: Z3 requires C++20. Install g++ 10+ or clang++ 10+
|
||||||
|
|
||||||
|
### Long Build Times
|
||||||
|
- **Normal**: 15-17 minute builds are expected for Z3
|
||||||
|
- **Never cancel**: Set timeouts appropriately and wait for completion
|
||||||
|
- **Optimization**: Use `make -j$(nproc)` for parallel compilation
|
||||||
|
|
||||||
|
## Key Projects in Codebase
|
||||||
|
|
||||||
|
Z3 is organized into several key components:
|
||||||
|
|
||||||
|
- **Core SMT**: `src/smt/` - Main SMT solver engine
|
||||||
|
- **SAT Solver**: `src/sat/` - Underlying boolean satisfiability solver
|
||||||
|
- **Theories**: Various theory solvers (arithmetic, arrays, bit-vectors, etc.)
|
||||||
|
- **Abstract Syntax Trees**: `src/ast/` - Expression representation and manipulation
|
||||||
|
- **Tactics**: `src/tactic/` - Configurable solving strategies
|
||||||
|
- **API**: `src/api/` - Public C API and language bindings
|
||||||
|
- **Parsers**: SMT-LIB2, Dimacs, and other input format parsers
|
||||||
|
- **Model Generation**: Creating and manipulating satisfying assignments
|
||||||
|
|
||||||
|
The architecture is modular with clean separation between the core solver, theory plugins, and user interfaces.
