Intro to GUI with QT 4.7 and OpenGL

QT 4.7 is a pain to install - luckily this Dockerfile should take care of everything for you in that regard.

Setup

You could have other projects in subdirectories under app/. Just pass in the build directory as the BUILDDIR arg:

docker build . -t qt --build-arg BUILDDIR=spin-slide

You'll need to set up X11 Forwarding. On MacOS I used this article. Here is the short version of the set up from the article:

brew install socat
brew cask install xquartz

!!IMPORTANT!! You need to log out of MacOS before proceeding!

Then open Xquartz and enable allow connections from network clients.

open -a Xquartz

Leave Socat running in a shell:

socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"

Get your inet IP address:

ifconfig en0

Start up the container, (with subproject path if needed):

docker run -e DISPLAY=IP_ADDRESS:0 qt:latest
