# WIP
```
-## Building (on Linux x86_64, with bash)
-
-### Python Environment
-First, make sure a virtual environment is set up with Cython and twine:
-
-```
-$ python -m venv .env
-$ source .env/bin/activate
-(.env) $ pip install --upgrade -r requirements.txt
-[...]
-(.env) $
-```
-
-### Cython extensions
-Compile the Cython extensions to C:
-
-```
-(.env) $ cython sfpy/*.pyx
-(.env) $
-```
-
-### Static libraries
-The extension module depends on the softposit and softfloat static libraries.
-They can be built with the following:
-
-```
-(.env) $ (cd SoftPosit/build/Linux-x86_64-GCC/; make clean; make)
-[...]
-(.env) $ (cd berkeley-softfloat-3/build/Linux-x86_64-GCC/; make clean; make)
-[...]
-(.env) $
-```
-
-Note that some changes are needed to the Makefiles so that the libraries are
-compiled with the correct options. Both libraries need to use -fPIC, and
-SoftPosit may need -std=c99 to work on older versions of GCC. See the
-diff below.
-
-### Building locally
-The extension modules can be built in place in the usual way:
-
-```
-(.env) $ python setup.py build_ext --inplace
-[...]
-(.env) $
-```
-
-A local wheel (compatible with the python version installed in the virtual
-environment) can be built with the following:
-
-```
-(.env) $ python setup.py bdist_wheel
-[...]
-(.env) $
-```
-
-The local wheel will be created in the dist/ directory. This is the recommended
-way to install the package when building it from source locally:
-
-```
-$ pip install dist/sfpy*.whl
-[...]
-$ python
->>> from sfpy import *
->>> Posit8(1.3)
-Posit8(1.3125)
->>>
-```
-
-### Building manylinux1 wheels for distribution
-Widely compatible linux wheels can be built with the help of PyPA's manylinux
-docker image. This requires that Docker is installed, and that the host can pull
-the proper docker image.
-
-To build the manylinux wheels, run:
-
-```
-$ sudo docker run -u $(id -u) --rm -v `pwd`:/io quay.io/pypa/manylinux1_x86_64 /io/docker-build-wheels.sh
-[...]
-$
-```
-
-This will create a set of manylinux1 wheel files in the wheelhouse/ directory.
-
-The docker build will make its own static libraries as part of the build process,
-and delete any existing static libraries with `make clean`.
-
-The wheels can be uploaded to PyPI (if you're the package maintainer) with
-
-```
-(.env) $ twine upload --repository-url https://test.pypi.org/legacy/ wheelhouse/*
-[...]
-(.env) $
-```
-
-to test on test PyPI, or
-
-```
-(.env) $ twine upload wheelhouse/*
-[...]
-(.env) $
-```
-
-for a release.
-
-### Makefile customizations
-The Makefiles used to build the static libraries need a few small tweaks to
-make sure that all the right flags are given to gcc. The changes are shown
-in the following diffs.
