Installation instructions should be extended to list dependencies

[yarikoptic]

README.md just says

Getting Started
If you want to run COINSTAC as a user

Download the latest release for your operating system here.

downloading the tarball for linux and trying to run it on a minimally installed Debian system would not work.

Here is an example demonstrating it via singularity container environment:

although it can be expected to find core libraries like that on any Linux system with a configured desktop environment, there should be a list of dependencies so e.g. those who would like to create a container with coinstac did not have to discover them by trial/error

[yarikoptic]

FWIW, here is the adjusted Singularity file with seems to be minimally sufficient list of dependencies:

Bootstrap: docker
From: neurodebian

%post
   apt-get update -qqq
   apt-get install -q -y libglib2.0-0 libnss3 libgtk-3-0 libx11-xcb1 libxss1 libasound2 libcanberra-gtk-module
   apt-get clean
   rm -rf /var/lib/apt/lists/*

Interesting, I was unaware of issues with the built app running on minimal linux systems, thanks for generating that list!

I assume these are most likely dependencies required by Chromium/Electron, I'll see if I can find more documentation on what is required by them

@yarikoptic after a bit of further thought I'm a little confused about the issue, are you trying to start the coinstac executable with a linux distro that does not have a desktop environment? If so, what would be the benefit packaging the GUI with a container that you could not view or use the application from?

[yarikoptic]

a GUI != the GUI. Could have been qt , but seems to be gtk, so at least GTK libs should be explicitly listed. I have just grown a list trial by trial, could be shorter I guess ;)

[everner]

@yarikoptic Can you please describe the use case here? Why would you want to install COINSTAC on a minimal Linux system?

[yarikoptic]

Sorry for answering a question with a question, but overall answer would be: why would you use containers?

In my case it was -- to provide review of coinstac for JOSS, and test installation in an environment with some isolation, so possibly to minimize possible affects of running an arbitrary executable downloaded from the web. I could also recommend coinstac to distribute "stock (singularity) coinstac containers" to further simplify its deployment in some use cases where the container would come with all necessary and guaranteed to work together components.
