Heroku buildpack with Cairo (and Pixman and FreeType)

heroku-buildpack-cairo

I am a Heroku buildpack that installs Cairo and its dependencies (Pixman and FreeType) into a dyno slug.

When used with heroku-buildpack-multi, I enable subsequent buildpacks / steps to link to this library. (You'll need to use the build-env branch of @mojodna's fork for the build environment (CPATH, LIBRARY_PATH, etc.) to be set correctly.)

Using

Composed

You'll almost certainly want to use this in conjunction with one or more additional buildpack.

When creating a new Heroku app:

heroku apps:create -b https://github.com/mojodna/heroku-buildpack-multi.git#build-env

cat << EOF > .buildpacks
https://github.com/mojodna/heroku-buildpack-cairo.git
https://github.com/heroku/heroku-buildpack-nodejs.git
EOF

git push heroku master

When modifying an existing Heroku app:

heroku config:set BUILDPACK_URL=https://github.com/mojodna/heroku-buildpack-multi.git#build-env

cat << EOF > .buildpacks
https://github.com/mojodna/heroku-buildpack-cairo.git
https://github.com/heroku/heroku-buildpack-nodejs.git
EOF

git push heroku master

Building

Cairo et al were built in a cedar stack image using the following steps.

chroot preparation:

mkdir app tmp
sudo /vagrant/bin/install-stack cedar64-2.0.0.img.gz
sudo mount -o bind /dev /mnt/stacks/cedar64-2.0.0/dev/
sudo mount -o bind /home/vagrant/tmp /mnt/stacks/cedar64-2.0.0/tmp/
sudo mount -o bind /home/vagrant/app /mnt/stacks/cedar64-2.0.0/app/

Preparation:

cd tmp/
curl -LO http://cairographics.org/releases/pixman-0.30.2.tar.gz \
     -LO http://cairographics.org/releases/cairo-1.12.16.tar.xz \
     -LO http://download.savannah.gnu.org/releases/freetype/freetype-2.5.0.tar.bz2 \
     -L "http://downloads.sourceforge.net/project/giflib/giflib-4.x/giflib-4.2.3.tar.bz2?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fgiflib%2F&ts=1384049147&use_mirror=softlayer-dal" -o giflib-4.2.3.tar.bz2
sudo chroot /mnt/stacks/cedar64-2.0.0
