Why does the QtSDK 1.1 install in a few minutes, whereas Qt4.7.1 install takes hours?

I'm referring to the new beta on the one hand, and the configure/make/make install from the previous release, on the other. Not a problem; just wondering, really.

May be I get you wrong, but the NokiaSDK is a binary release, so the Trolls had make the "configure" and "make" for you already and you only have do the the "make install". And building the framework is the time consuming part here. That's the difference between a binary release and a building from source.

Oh of course, thanks.

Well ,yesterday i installed qt from source . Le's see how many hours it took :

11 hours

I typed "make" in cmd at 12 .10 PM (mid noon ) thinking that it won't take more than 30 mins . Make completed successfuly at 11.30 PM .!!!! ( everybody slept )
My lap got heated up......

Besides , take a look at my lap configuration :

Intel Core2Duo Processor T6400
3.00 GB RAM
2.0 Ghz
About 25 Gb free
I stopped all other memory consuming services ( not even chrome )
It consumed about 8.5 gb after make. Fortunately , after "make clean " i recovered space.

Many users have reported this issue in several forums ......
I assume this happens only in Windows.

About 2hrs for me on a high-end 2009 desktop running Ubuntu.

The most important*** component of your system (when building big libraries) is the hard drive.

***to be read as: has the biggest impact on the time of the build.

I didn't timed exactly (even if i built Qt many times), but my times are: about 2.5 hours on desktop (E6550, 2GB ram and 500 GB HDD), and on an mobile system a little more than 3 hours(T2350, 2GB ram, 160GB HDD)

...and the biggest pig, in my experience, is WebKit, a monolithic rat's nest of code that takes well over half the total build time if it decides to build at all. This component is in desperate need of streamlining and modularization. If you don't need it, you can tell 'configure' to skip it and you'll be far better off. Not to mention you'll be done a whole lot sooner.
