Use the latest version of GraphicsMagick (1.3.23) inside Heroku.
Insert the buildback before the main buildpack for your application:
heroku buildpacks:add --index 1 https://github.com/mcollina/heroku-buildpack-graphicsmagick.git
The next time you push your application it should install graphicsmagick before your application buildpack.
For more info see: https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app
To change this buildpack, fork it on Github. Push up changes to your fork,
then create a test app with
--buildpack <your-github-url> and push to it.
To change the vendored binaries for ImageMagick, use the helper scripts
You'll need an S3-enabled AWS account and a bucket to store your
The bucket name and imagemagick version are stored in the configs.sh file,
so update it there (if you plan to contribute back to this repo, do this
in a separate commit).
To rebuild the ImageMagick package, you can:
$ export AWS_ID=xxx AWS_SECRET=yyy $ s3 create $S3_BUCKET $ support/package_graphicsmagick
Commit and push the changes to your buildpack to your Github fork, then push your sample app to Heroku to test. You should see:
-----> Downloading graphicsmagick YOUR_IMAGE_MAGICK_VERSION_HERE
There is also a
Vagrantfile which can be used with
Vagrant to build a
cedar-14 virtual machine
using Heroku's own open-source provisioning scripts. This allows you to build
and test your changes in a local VM with a shared filesystem rather than having
to push your changes up to Github and building on Heroku.
To build with VMs install Vagrant and then run
vagrant up. Once it completes you will have a VM named
cedar-14. Vagrant by
default will map your project folder to
/vagrant on the VM's filesystem.
Heroku dropped the cedar stack on November 4th, 2015. If you still need to run this buildpack on cedar for whatever reason you can do by referencing an older version of the buildpack:
heroku buildpacks:add --index 1 https://github.com/mcollina/heroku-buildpack-graphicsmagick.git#35f87dd
