OSQP

This repository automates OSQP wheel building using multibuild, Travis CI, and AppVeyor.

How it works

The wheel-building repository:

• does a fresh build of any required C / C++ libraries;
• builds a osqp wheel, linking against these fresh builds;
• processes the wheel using delocate (OSX) or auditwheel repair (Manylinux1). delocate and auditwheel copy the required dynamic libraries into the wheel and relinks the extension modules against the copied libraries;
• uploads the built wheels to a Rackspace container - see "Using the repository" above. The containers were kindly donated by Rackspace to scikit-learn).

The resulting wheels are therefore self-contained and do not need any external dynamic libraries apart from those provided as standard as defined by the manylinux1 standard.

Triggering a build

You will likely want to edit the .travis.yml and appveyor.yml files to specify the BUILD_COMMIT before triggering a build - see below.

You will need write permission to the github repository to trigger new builds on the travis-ci interface. Contact us on the mailing list if you need this.

You can trigger a build by:

• making a commit to the osqp-wheels repository (e.g. with git commit --allow-empty); or
• clicking on the circular arrow icon towards the top right of the travis-ci page, to rerun the previous build.

In general, it is better to trigger a build with a commit, because this makes a new set of build products and logs, keeping the old ones for reference. Keeping the old build logs helps us keep track of previous problems and successful builds.

Which osqp version does the repository build?

The osqp-wheels repository will build the commit specified in the BUILD_COMMIT at the top of the .travis.yml and appveyor.yml files. This can be any naming of a commit, including branch name, tag name or commit hash.

NB: The directory osqp_sources must be updated to the latest repository version in order to have all the commits.

PyPI

Download wheels from bintray.com

./download_wheels.py $BUILD_COMMIT

where BUILD_COMMIT can be anything like v0.3.1. This script will download the wheels in to the tmp/ folder.

Upload wheels to PyPI

twine upload tmp/*

For the twine access user and password ask Bartolomeo Stellato.
