Hello and sorry for the delay. As I said, I've been busy.

I was hoping for a more structured approach to porting to Qt 5, such as
going over the list of changes and checking how each one affects Stellarium
(if it affects it at all). I had a link to that changelog somewhere...
Also, there's the issue of packaging library files by the Windows installer
- I understand that Qt 5 split the large ones into multiple libraries.

Before I left for Sofia, I tried to build Stellarium on Windows to see to
what extent it will work on my computer. There are a few compile time
errors, and a linking error. The code errors are fixable, the linking error
resulted in Qt Creator reporting an error for each use of a Qt class,
resulting in over ten thousand error reports, which mostly froze the
system. :) At that point, I decided that what was left of my free time
wasn't worth wasting on debugging that problem.

The problem is that my main computer at the moment is a netbook (old
form-factor since replaced by tablets) with an *integrated* Intel GMA
graphics card which supports OpenGL only up to 1.4 + some extensions. (As
far as I know, that chip was quite popular at one time and quite a lot of
not-so-old portable computers still use it.) This means that if the
migration is completed, I won't be able to contribute to Stellarium in a
meaningful way until I get a new computer.
