This project is a Scalingo buildpack to use latest version of GraphicsMagick (1.3.36) alongside your app.

It doesn't do anything else, you have to use it alongside another buildpack thanks to the mutli-buildpack.

To use this buildpack, you should prepare .buildpacks file that contains this buildpack url and your real buildpack url.

$ cat .buildpacks
https://github.com/Scalingo/graphicsmagick-buildpack.git
https://github.com/Scalingo/ruby-buildpack.git

The first buildpack will install GraphicsMagick utilities in /app/bin, the second will handle the deployment of your ruby application. For any other technology, go to http://doc.scalingo.com/buildpacks/

$ scalingo env-set BUILDPACK_URL=https://github.com/Scalingo/multi-buildpack.git
$ git push scalingo master
...

You can verify the installation of GraphicsMagick with the following command.

$ scalingo run "gm version"

You could upload the desired version of GraphicMagick from GraphicMagick sources on a S3 for example. Then using the environment variable GRAPHICS_MAGICK_ARCHIVE_URL to specify the archive location, following the example:

scalingo env-set GRAPHICS_MAGICK_ARCHIVE_URL=https://hg.osdn.net/view/graphicsmagick/GM/archive/GraphicsMagick-1_3_36.tar.gz

Note that Scalingo provide only support of the default version defined in configs.sh file. We do not guarantee the proper functioning of the build in case of usage of other versions.

To change this buildpack, fork it on Github. Push up changes to your fork, then create a test app with BUILDPACK_URL=<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 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 GraphicsMagick package for stack 'scalingo-20', you can:

$ docker run --rm -v $buildpack_path:/buildpack -it scalingo/scalingo-20:v1 bash
$ apt-get install s3cmd
$ cd /buildpack
$ export S3_ACCESS_KEY=xxx S3_SECRET_KEY=yyy STACK=scalingo-20
$ support/package_graphicsmagick

Commit and push the changes to your buildpack to your Github fork, then push your sample app to Scalingo to test. You should see:
