Support for this is now included in the main Python buildpack. This is only up for legacy reasons. Please don't use it.

A helper buildpack to get CFFI and projects that use it working on Heroku.

First set your BUILDPACK_URL to https://github.com/ddollar/heroku-buildpack-multi.git:

$ heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git

Create the .buildpacks config for buildpack-multi:

$ cat .buildpacks
https://github.com/ddollar/heroku-buildpack-apt
https://github.com/coderanger/heroku-buildpack-cffi
https://github.com/heroku/heroku-buildpack-python

And then create the Aptfile config for buildpack-apt:

$ cat Aptfile
libffi-dev

Then just put the Python libraries you need in the normal requirements.txt.

If you are building CFFI for Cryptography, no additional configuration should be required.
