10 GB of compiled QT

[wysota]

No, I did not, I was not aware that it even exists. I did not find "make.exe" in opensource distribution. M-soft "nmake", used in Windows install of QT, does not have that option. Can you advise me on the details of how to clean up temp files after installation?

It's not an option of make or nmake. It's a compilation rule that is created by the configure script. Just run nmake clean and it will work.

As to the original question: it has become normal for the newer versions of Qt to take up that much space directly after compilation. You should be able to save a lot of space by excluding phonon and the demos and examples from the build.

Phonon is not that bad. WebKit is the worst one.

Wysota you should see on my Gentoo box QtWebKit is 350MB since I have strip disabled. If I enable strip it goes all the way down to 30MB

That's after compilation, not during it. Strip is performed only when the binaries are installed. All the intermediate (mostly .o) files take up few gigabytes.

Well they can use the -prefix <dir> to install to a specific folder after copying the mkspecs to that folder. do nmake install and that would reduce alot of space and it only installs the stuff Qt requires and they can delete the original qt folder that they were building from. Also disable stuff they do not need too.

The problem is the switch doesn't exist on Windows anymore. You can only have an in-place install there. And besides, this doesn't really reduce the space requirement for building Qt, it only moves it elsewhere. "(n)make clean" will remove all intermediate files, so that is enough, one doesn't have to do any other tricks. But QtWebKit still requires a few gigabytes to build, especially if you build in both debug and release modes at once.

Strange the -prefix worked for me the other day :S

People reported it's not there anymore (on Windows, of course). I haven't checked it myself, I just follow what they said.

Not sure if its there in 4.5.1, but it was available till 4.5.0 . Refer this thread in which I had discussed the same with you

Then it's probably still available. I just assumed the person stating it's not there knew what (s)he was saying...
