QT minimum build to start developing

[lurky]

Hello,
I just started playing with QT but have an uncertainty about building it under VS2008.

I used the following configuration command
configure -debug-and-release -opensource -static -platform win32-msvc2008

followed by the suitable "nmake" command, but after several hours of compiling I noticed that also tutorials, demos, examples and a lot of other stuff were compiled, so that the "qt" folder was over 8GB in size (I then stopped building).

Is there a way (configuration parameter? makefile editing?) to build only the parts needed to start developing projects? (I think just .lib files for static building and .lib + .dll for dynamic, correct?)

Thanks a lot.

Its a subdirs project so it will compile everything inside.
As quick work around, rename examples and demos folder before config and build.

[lurky]

Thank you.
So if I want to carry around my "minimum build" which folders are necessary?
Should I need only "include", "bin" and "lib" folders?

Try configure -help and see if Windows release contains options to disable building examples, demos, etc. It should be called something like "-no-make-examples" and similar.

that was the first think I looked for and unfortunately there is not such an options
I also tried the '-fast' switch and then used 'nmake' from inside the 'src' folder but this ended up with a 'missing something' error

[wysota]

Missing what exactly?

[lurky]

I don't remember if the error was related to a missing file or to an unresolved reference during linking, anyway I found that my installation of the QT SDK may have been damaged after all my trials so I'm going to install it again.

Theoretically, using configure with -fast switch and then nmake from inside the src folder has a sense?

I'm starting to think that my only possibilty is to manually edit the Makefile (after configure without -fast) or the projects.pro (before configure) in the %QTDIR%, what do you think about?

[wysota]

It couldn't have been damaged unless you started changing the source code of Qt which I assume you didn't. Don't touch the makefiles. Configure Qt as usual, cd into src and call nmake.

I'm sure everybody understands "minimum build" in his own way. Here is how i do my minimum build (e.g. Qt 4.5.2).

./configure -prefix /usr/local/qt-4.5.2 -nomake demos -nomake examples -no-qt3support 
-no-accessibility -no-phonon -no-phonon-backend -no-webkit

./configure -prefix /usr/local/qt-4.5.2 -nomake demos -nomake examples -no-qt3support 
-no-accessibility -no-phonon -no-phonon-backend -no-webkit

To copy to clipboard, switch view to plain text mode 

But it may differ from your needs, because i don't know what kind of application you want to develop.

I'm building in Windows targetting to VS2005, and -prefix is not listed in configure help: what is it for?

Anyway my meaning for "minimum" is the smallest set of files needed to develop an application (with all the possible libraries) using the VS2005 integration.
So I think I would:
- need folders 'include', 'lib', 'plugins' and 'bin'
- not need folders 'src', 'examples', 'tutorials', 'demos'
- don't know about remaining files and folders

Am I correct?

[wysota]

Of course I did NOT changed the libraries code but just played with makefiles.

Makefiiles get regenerated when you run configure.

But for safety reasons I reinstalled the SDK.

Pure waste of time, especially that the SDK is built for MinGW.

Now, how can I just build WebKit?

Giving information that you encountered some error isn't really helpful. I could only reply you needed to do something to make them go away.

It's for installing the binaries outside the source tree. But it's unavailable on Windows.

You need to build the sub-src, sub-tools and possibly the plugins targets then.

But I need all the SDK to have designer, linguist and other tools. Correct?

You're absolutely right, unfortunately I did not take a note of the exact error but if there's a way to build just WebKit I can make a fast try.

How can I achieve this?
What about my assumption about minimum set of required files/folders?

Thank you for you answers.

Incorrect.

Configure with WebKit, cd into appropriate directory and run nmake. Note that Qt libraries need to be compiled first.

How can I achieve this?

Call nmake with appropriate target names (such as sub-src).

Update.
Of course I did NOT changed the libraries code but just played with makefiles. But for safety reasons I reinstalled the SDK. Then I started a new building (full, including demos, tutorials, examples) and got an "unresolved reference" while building WebKit. I finally restarted a new building with -WebKit switch and it was successful (or so it looks...).
The final size of the Qt folder is a bit more than 3GB, which is acceptable compared to the 8Gb and more of my first trial.

Now, how can I just build WebKit?

Thanks to all the ones who may help.
