Qtopia core howto
we need qtopia to find the compiler (symlinks & path)
$ cd path-to/gumstix-oe/tmp/cross/bin ; for f in arm-angstrom-linux-gnueabi-*; do n=$(echo $f|cut -b 28-); ln -s $f arm-linux-$n; done $ PATH=$PATH:path-to/gumstix-oe/tmp/cross/bin/ ; export PATH
download and unpack
$ wget ftp://ftp.trolltech.com/qt/source/qtopia-core-opensource-src-4.4.0-beta1.tar.gz $ tar xzvf qtopia-core-opensource-src-4.4.0-beta1.tar.gz ; cd qtopia-core-opensource-src-4.4.0-beta1/
as of release candidate 1, the name has changed from qtopia to qt-embedded. The source file is now
qt-embedded-opensource-src-4.4.0-rc1
configure, make and make install
$ ./configure -embedded arm -little-endian -prefix /qtopia ; make ; sudo make install
if you want to use the touchscreen for mouse input, it is best to include the tslib mouse driver configuration for qt-embedded. The correct configuration is:
$ ./configure -embedded arm -little-endian -prefix /qtopia -qt-moust-tslib; make ; sudo make install
tar and move it to gumstix (~83 MB including examples & demos)
$ tar cvf ~/qtopia-core.tar --exclude=doc /qtopia
gumstix: $ tar xvf qtopia-core.tar -C /media/cf ; ln -s /media/cf/qtopia/ /qtopia
qtopia needs libstdc++, move it to your gumstix's /lib or somewhere it can be found
$ cd path-to/gumstix-oe/tmp/staging/arm-angstrom-linux-gnueabi/lib/ $ tar cfv ~/libstdc++.tar libstdc++.so*
libstdc++.so libstdc++.so.6 libstdc++.so.6.0.8
gumstix: $ tar xvf libstdc++.tar -C /lib
set variables for qtopia & calibrate touchscreen
$ export QWS_MOUSE_PROTO='LinuxTP:/dev/input/touchscreen0' $ /qtopia/examples/qtopiacore/mousecalibration/mousecalibration -qws &
if you are using the tslib then you should calibrate the touch screen using ts_calibrate instead of the mousecalibration example. The environment variable QWS_MOUSE_PROTO should be set to tslib:/dev/input/touchscreen0
$ export QWS_MOUSE_PROTO='tslib:/dev/input/touchscreen0'
