Use the latest version of GraphicsMagick inside Heroku Cedar. At the moment it is bundled the version 1.3.18.
This buildpack is built to be used through heroku-buildpack-multi, so in your app you need to:
heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi
Then, create a .buildpacks file inside your app:
https://github.com/mcollina/heroku-buildpack-graphicsmagick
https://github.com/heroku/heroku-buildpack-nodejs
This example was based on the nodejs buildpack, but it can be used with any other. If it is not working with yours, please report a bug.
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
in the support/ subdirectory.
You'll need an S3-enabled AWS account and a bucket to store your
binaries in.
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:
