How to write the system requirements for the application?

Question

Programming

It is required to write the minimum and recommended system requirements:

OS:
Processor:
RAM:
Video adapter: Hard disk
space:
Availability on the computer:

How to fill it all in correctly, there are no platforms for testing. The application is written in Qt Creator 3.6.1, in Qt 5.6.0 С++, compiler - MinGW 4.9.2 32bit. In the OpenGl application, in the manager, it eats no more than 40 MB of memory.

Answer 1

OS - calculated based on libraries, api and other things. Most likely you can pull out of Qt + OpenGL
From the processor to the space on the HDD - look at your computer in the manager - how much it eats, and extrapolate with a margin.
Availability on the computer - again depends on the libraries and other things.
For accuracy - put a virtual machine, and check.

Answer 2

Is your car comfortable? Here, write it off.

Answer 3

Make Windows XP minimal, rent a VPS for testing, it's cheap, there will be Windows Server 2003 (XP), secondly, since Qt, it is very important to accurately determine all the libraries, it has a rather "cumbersome" and "insidious" dependency system .
