This repository contains the libpasta python bindings.
Currently, only 64-bit linux is supported through manylinux, but we are aiming to support more platforms.
For compiling from source, SWIG is required to produce the library bindings, but these will be added pregenerated when the library has stabilised.
The python libpasta bindings have been packaged, and can be installed using
pip install libpasta. These are precompiled wheels for linux systems, and
currently include static libpasta bindings and other libraries.
When libpasta is more widely available as a shared library, we will distribute libpasta-py as a simple wrapper.
Unfortunately, on some systems we are encountering this bug: psycopg/psycopg2-wheels#2
Which we can patch if it continues being a problem. If Arch is the only affected system, a source build as below can be used.
The included setup.py file in the libpasta-py repository will build the
package either using a static libpasta, or the shared version.
Both of these depend on the pasta-bindings/ submodule which contain
the swig bindings, which the setup file handles automatically.
If building the static version (with the BUILD_STATIC=1 env set)
then additionally the pasta-bindings/libpasta-ffi submodule is needed to build
the library.
In the simplest case, building wrappers for the shared library should be as straightforward as:
python setup.py bdist_wheel # build the wheel file for installation
pip install dist/libpasta-{version}-{build}.whl # install the library
And for building the static version (requires Rust)
git submodule update --init --recursive # update the submodules
BUILD_STATIC=1 python setup.py bdist_wheel # build the wheel file for installation
pip install dist/libpasta-{version}-{build}.whl # install the library
To build all the wheels for distribution:
docker run --rm -v pwd:/io quay.io/pypa/manylinux1_x86_64 /io/build-wheels.sh
(Recommended: pre-install Rust and others on a docker image, and comment out the rustup command)
