I have tried to build simplegles-qml in windows but can't resolve a linking problem. I may be missing some dependances. The plugins build

I then tried to build in Linux but can't get seem to get it to find the Qt5.1.1 I installed
I am probably missing something.

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

The main changes are:
 - got rid of the renderer-related code: use OpenGL ES2 only instead
-> allowed to simplify and optimize opengl code (especially text
rendering is now much simpler and faster).
 - switch to Qt5: the base widget architecture have been simplified.
Startup time is much faster, we can now use QML together with the old
GUI code. This is a good first step toward having a QML only GUI.

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.
 
 - did some tuning on default stars rendering (so that the sky looks
nicer by default)
 - cleanup up extinction code, fixed bugs in it
 - got rid of the Gettext dependency at run time. The code in this
branch now use Qt translation feature. The translation files are still
based on .po/.pot and gettext tools and are compatible with Launchpad
translation feature (the .po are just translated to .qm files instead
of .mo).

Remaining issues:
 - some more testing must be performed on plugins
 - planets shadows is still broken

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 question is: would you guys agree to merge this into the trunk?
The side effect is broken compatibility for some old configs
(including the one from Bogdan apparently :/ )

Bogdan, if it's a problem, we can use Stellarium's donation money to
buy you a video card?

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.
