README.kde-qt

[Michael Jansen]

Hi

I just checked kdesvn-build and README.kde-qt from our qt clone because i consider them the main authorities for how to build a qt for usage with kde.

Problem is they do it differently.

kdesvn-build uses 

	configure-flags -qt-gif -no-exceptions -fast -qdbus \
	                -nomake examples -nomake demos \
	                -phonon # Phonon built as part of Qt now

README.kde-qt tell us to use

 ./configure -qt-gif -debug -fast -no-separate-debug-info \
     -system-libpng -system-libjpeg -system-zlib \
     -dbus -webkit -plugin-sql-mysql \
     -nomake examples -nomake demos -prefix <installdir>

If we consider the options specified that are default anyway

    -no-gif ............ Do not compile the plugin for GIF reading support.
 *  -qt-gif ............ Compile the plugin for GIF reading support.
                         See also src/plugins/imageformats/gif/qgifhandler.h

   # typo in kdesvn-build.
    -no-dbus ........... Do not compile the QtDBus module.
 +  -dbus .............. Compile the QtDBus module and dynamically load libdbus-1.
    -dbus-linked ....... Compile the QtDBus module and link to libdbus-1.

    -no-phonon ......... Do not build the Phonon module.
 +  -phonon ............ Build the Phonon module.
                         Phonon is built if a decent C++ compiler is used.

    -no-webkit ......... Do not build the WebKit module.
 +  -webkit ............ Build the WebKit module.
                         WebKit is built if a decent C++ compiler is used.

	# the same for all system-libxyz from README.kde-qt
    -no-libpng ......... Do not compile in PNG support.
    -qt-libpng ......... Use the libpng bundled with Qt.
 +  -system-libpng ..... Use libpng from the operating system.
                         See http://www.libpng.org/pub/png

we end up with
	kdesvn-build:  -fast -nomake examples -nomake demos -no-exceptions 
and
    README.kde-qt: -fast -nomake examples -nomake demos -debug -no-separate-debug-info -plugin-sql-mysql -prefix <installdir>

Real Differences:
#################

-no-exception:
--------------
Disables this XmlPattern thing and makes compiling koffice and i think some plasma stuff impossible. qtscriptgenerator unconditionally assumes it to be set so you have to patch it to compile it. Is this still recommended?

-plugin-sql-mysql
-----------------
I think this one broke akonadi/nepomuk for me. i got a crash. See atachement. I vanished after i recompiled qt without it but i'm not really sure it's the reason. Perhaps someone else can double check.


Missing?
########
or should at least be mentioned?

-developer-build	-> For kde developers. Enables some additional stuff used internally by qtsoftware. Some additional warnings for example.
-plugindir			-> If libdir is mentioned this one should be mentioned too.

How about phonon?
#################
Do we recommend using the qt phonon these days? If yes is that how to build xine plugin if using phonon from qt problem solved?

Anything Else?
##############

I would like to get a consistent recommendation how to build qt for kde out there.

What's bothering me is the difference between the '*' and '+' above in qt's configure --help output. I can't explain or find out how these affect stuff. But i would like to have the list of options as short as possible.
