[erlang-questions] How to get wxerlang working in in Ubuntu 14.04.4 LTS

[Stefan Houtzager]

Hi,

I would appreciate an installscript for a recent erlang version on Ubuntu
14.04.4 LTS with wxerlang working.
  I am a starting elixir developer (and for that need erlang). I would like
to get wxerlang working and created a dockerimage to make my installation
easy portable. I use otp_src_18.3.tar.gz and install several wx packages
and others, I'm not sure if I miss some or install some that are not
needed. Anyway, after the install the output of which wx-config &&
wx-config --version-full is

/usr/bin/wx-config
2.8.12.1

But wx:demo(). results in an error:

Eshell V7.3  (abort with ^G)
1> wx:demo().
Error: Unable to initialize gtk, is DISPLAY set properly?
ok
2>

The most important installs in the dockerfile (just linux commands after
the RUN statements, phusion/baseimage:0.9.18 is Ubuntu 14.04.4 LTS reworked
for docker)  I copied below, the full dockerfile and the logging of the
output I arttached.

# Important!  Update this no-op ENV variable when this Dockerfile
# is updated with the current date. It will force refresh of all
# of the base images and things like `apt-get update` won't be using
# old cached versions when the Dockerfile is built.

# Set correct environment variables.

# Setting ENV HOME does not seem to work currently. HOME is unset in Docker
container.
# See bug : https://github.com/phusion/baseimage-docker/issues/119
#ENV HOME /root
# Workaround:
RUN echo /root > /etc/container_environment/HOME

# Regenerate SSH host keys. baseimage-docker does not contain any, so you
# have to do that yourself. You may also comment out this instruction; the
# init system will auto-generate one during boot.
RUN /etc/my_init.d/00_regen_ssh_host_keys.sh

# Use baseimage-docker's init system.
CMD ["/sbin/my_init"]
