Installation
############
nanopy includes ``C`` extensions for work generation and signing.

.. code-block:: bash

   sudo apt install gcc python3-dev
   pip install nanopy

* Instead of the default (``gcc``), point to another ``C`` compiler by prepending the installation command with ``CC=path/to/c/compiler``.

  .. code-block:: bash

     CC=path/to/c/compiler pip install nanopy

  * Refer to ``setuptools`` documentation for other compiler and linker options. For, e.g, to link to ``libomp``,

    .. code-block:: bash

       LDFLAGS=-lomp pip install nanopy

* For GPU, appropriate ``OpenCL ICD`` headers are required.

  .. code-block:: bash

     sudo apt install ocl-icd-opencl-dev nvidia/amd-opencl-icd

  * Enable GPU usage by prepending the installation command with ``USE_GPU=1``.

    .. code-block:: bash

       USE_GPU=1 pip install nanopy
