Prerequisites:
Prerequisites:
* any scratchbox ARMEL target, tested with [[CSSU-thumb toolchain setup (gcc4.7.2-linaro)]]
* any scratchbox ARMEL target, tested with [[CSSU-thumb toolchain setup (gcc4.7.2-linaro)]]
-
* Xlib-xcb.h and libX11-xcb.so build from http://maemo.org/packages/source/view/fremantle_sdk_free_source/libx11/1.1.99.6+0m5 (build with --with-xcb)  
+
** We still run this build commands '''outside''' of scratchbox and only use the toolchain and sysroot (like with MADDE or for Raspberry Pi etc.)
-
** We would need to deliver libX11.so.6 too, but --with-xcb breaks keyboard support for system apps
+
* Xlib-xcb.h and libX11-xcb.so build from http://maemo.org/packages/source/view/fremantle_sdk_free_source/libx11/1.1.99.6+0m5 (build with --with-xcb) moved to ${MADDEROOT}/sysroots/fremantle-arm-sysroot-20.2010.36-2-slim/usr/include/X11/ (/usr/lib resp.)
-
** Solution: we install a copy of libX11.so with XCB supoort, named libXc11.so and link against this copy, so system binaries don't load it (tested, works reliably)
+
** <strike>Binaries available here: [http://repos.fuhlbrueck.net/qt5-maemo5/pool/main/libx/libx11/ repos.fuhlbrueck.net/qt5-maemo5/pool/main/libx/libx11/]</strike>
-
*** apt-get install libxc11-xcb-dev (with frafl's temporary Qt5 repo enabled, see [[Qt5-Maemo5]])
+
*** This does not work, we need a libX11.so build with xcb support, however this stops the keyboard from working in other applications
 +
** We install a copy of libX11.so with XCB supoort, named libXc11.so and link against this copy
 +
*** apt-get install -o Dpkg::Options::="--path-exclude=/usr/share/" libxc11-xcb-dev
*** all "-lX11" (and "-lX11-xcb") in the Qt sources have been changed to "-lX'''c'''11" ("-lX'''c'''11-xcb" respectively)
*** all "-lX11" (and "-lX11-xcb") in the Qt sources have been changed to "-lX'''c'''11" ("-lX'''c'''11-xcb" respectively)

Theoretically, you can even install this Qt build in scratchbox (untested):
-
  cd qtbase && fakeroot make install && cd ..

#only the first step should require root privileges

ln -s  /scratchbox/users/${USER}/targets/${TARGET}/opt/qt5 /opt/qt5

  cd ${GITROOT}/qtjsbackend && make install

  #... (some more as needed by qtdeclarative, e.g. qtsvg)

  /scratchbox/login

#change target to the target TARGET
