Installing ImageMagick & Ghostscript on Ubuntu

howto.md

1. You have Ghostscript installed, right? Otherwise sudo apt-get install ghostscript
2. This is important and installs the headers (iapi.h etc) which are required but don't come with the default Ghostscript package: sudo apt-get install libgs-dev
3. I also needed sudo apt-get install gs-esp
4. For me the pre compiled version of ImageMagick never accepted Ghostscript, so let's remove it: sudo apt-get --purge remove imagemagick
5. Get the source of ImageMagick, untar it, cd ImageMagick-xx
6. ./configure --with-gslib=yes [and what else you need]
7. Confirm in the output near the bottom gslib yes yes and not gslib yes no
8. make
9. make install
10. Run convert -list configure | grep DELEGATES => DELEGATES bzlib djvu freetype gs jpeg jng jp2 lcms png tiff x11 xml zlib
11. See the gs in there? You got it!

Thanks for this gist! It's a bit outdated, but here's what I got to work for me on Docker for a Rails app.

• gs-esp no longer exists
• If installing via a Dockerfile, the order matters (see below)
• it plays nice with imagemagick so no longer need to run make or make install 😄

FROM ruby:2.3.0

RUN apt-get update -qq && apt-get install -y \
  ghostscript \
  libgs-dev \
  imagemagick

Thanks! Simply adding "ghostscript" to our Dockerfile apt-get lines solved an issue with Rmagick, ImageMagick, and "Font not found".
