scalingo-buildpack-vips

heroku-buildpack-vips modified to work on Scalingo. Supported stacks:

• scalingo-18
• scalingo-20

---

A VIPS buildpack for the modern Heroku stacks. This stack supports the following stacks:

• heroku-16
• heroku-18
• heroku-20

If you have problems on any of these stacks, or if a new stack comes out that is unsupported, please file an issue.

Important notes:

This buildpack started out as one of the many that are out there, and ended up being completely different. The build script uses docker and also includes pdf support via poppler. In order to use this buildpack, you must install these packages in your heroku application:

• libglib2.0-0
• libglib2.0-dev
• libpoppler-glib8

The easiest way to do this is using the heroku apt buildpack.

This buildpack was put together with the help of John Cupitt, the creator of libvips. He was invaluable in my efforts to get a working libvips installation with pdf support on heroku. Thank you John!

Heroku buildpack with libvips installed.

Usage

Add this buildpack to your app:

Build script

This is the script used to build vips using docker.

VIPS_VERSION=x.y.z ./build.sh

After building a tar file, it will be copied to the build directory. Then you should commit this changes to git.
