Building Qt5 for the N900 (using scratchbox)
Prerequisites:
- any scratchbox ARMEL target, tested with CSSU-thumb toolchain setup (gcc4.7.2-linaro)
- We still run this build commands outside of scratchbox and only use the toolchain and sysroot (like with MADDE or for Raspberry Pi etc.)
- 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.)
-
Binaries available here: repos.fuhlbrueck.net/qt5-maemo5/pool/main/libx/libx11/- 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 "-lXc11" ("-lXc11-xcb" respectively)
-
Prepare your build environment

Now it's time to configure
configure for a build outside of scratchbox (standard for now)
#-no-c++11 is only needed because of a single bug (related to gcc4.7?) ./configure -no-c++11 -developer-build -opensource -nomake examples -nomake tests -confirm-license -device linux-maemo-n900-g++ -device-option CROSS_COMPILE=/scratchbox/compilers/${COMPILER}/bin/arm-none-linux-gnueabi- -sysroot /scratchbox/users/${USER}/targets/${TARGET}/ -qt-xcb -make libs -prefix /opt/qt5
configure within scratchbox instead (experimental)
PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig/ PKG_CONFIG_SYSROOT_DIR=/ ./configure -no-c++11 -developer-build -opensource -nomake examples -nomake tests -confirm-license -device linux-maemo-n900-g++ -qt-xcb -make libs -prefix /opt/qt5
Finally, we build Qt
make module-qtbase module-qtdeclarative
installation (build in scratchbox (s.a.))
cd qtbase && fakeroot make install && cd .. cd qtjsbackend && fakeroot make install && cd .. cd qtsvg && fakeroot make install && cd .. cd qtdeclarative && fakeroot make install && cd .. ln -s /opt/qy5/bin/qmake /usr/bin/qmake-qt5
Building Qt5 for the N900 (using MADDE)
Prerequisites:
- MADDE
- The same as for scratchbox
MADDEROOT=/opt/QtSDK/Maemo/4.6.2 #see scratchbox git clone ... #-sysroots redirects everything to a path under ${MADDEROOT} ln -s `pwd` ${MADDEROOT}/sysroots/fremantle-arm-sysroot-20.2010.36-2-slim`pwd` #**Remove** -mthumb in QMAKE_CFLAGS (does not work with current MADDE) vim qtbase/mkspecs/devices/linux-maemo-n900-g++/qmake.conf
Now it's time to configure and build:
#change if your host is not x86_64 ./configure -developer-build -opensource -nomake examples -nomake tests -confirm-license -device linux-maemo-n900-g++ -device-option CROSS_COMPILE=${MADDEROOT}/toolchains/arm-2007q3-51sb6-gdb71-arm-none-linux-gnueabi_linux_x86_64/bin/arm-none-linux-gnueabi- -sysroot ${MADDEROOT}/sysroots/fremantle-arm-sysroot-20.2010.36-2-slim -qt-xcb -make libs -prefix /opt/qt5 make module-qtbase module-qtdeclarative

Use prebuilt Qt5 to build
see t.m.o thread
Testing Qt5 on the N900
currently outdated, but a similar procedure will work again in the future
# as root, e.g. with sudo gainroot #not endless bandwidth, so use with care: echo "deb http://repos.fuhlbrueck.net/qt5-maemo5 fremantle main" >> /etc/apt/sources.list.d/hildon-application-manager.list #libX11-xcb1 is not optified, but tiny apt-get install libx11-xcb1 qt5-base qt5-declarative #only for now: ldconfig /opt/qt5/lib
