To install Basix, you must first install the C++ interface and library:
bash
cmake -DCMAKE_BUILD_TYPE=Release -B build-dir -S .
cmake --build build-dir
cmake --install build-dir
You may need to use sudo for the final install step. Using the CMake
build type Release is strongly recommended for performance.
To use Basix via Python, you will need to install the Basix Python
interface. First, you will need to install pybind11: pip install
pybind11. You can then install the Basix Python interface with:
bash
cd python
pip install .
Once you have installed the Basix Python interface, you can run the
Basix tests to check that everything is running correctly. First,
install pytest: pip install pytest. You can then run the tests with:
bash
pytest test/
Basix depends on xtensor
and xtensor-blas.
CMake will download install these packages if they cannot be found.
