Building a clojure dev machine on a pristine Ubuntu 16.04 Docker image

klapaucius-image.txt

# bash

apt-get update
# updates package list

apt-get install default-jre

apt-get install git
apt-get install wget
# oh yeah I need that too

# via http://stackoverflow.com/questions/25838169/installing-leiningen-2-on-ubuntu :

wget https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
chmod +x lein
mv lein /usr/local/bin

## download klapaucius

git clone https://github.com/Vaguery/klapaucius.git
cd klapaucius

Note: this leaves a bunch of complaints (since you're root in a Docker image) to set LEIN_ROOT. Whatever.

Notes on the bug-hunt:

• install jdk and lein as normal above
• lein repl (hit ENTER to get past root warning)
• paste this into REPL prompt(s):

  (def arg (* 2 Math/E))
  (Math/log arg)
  ;; on Intel machines: 1.6931471805599452
  (assert (= (Math/log arg) 1.6931471805599452))
  ;; fails, because on ARMv8 it doesn't equal that
