Hi all! i m a beginner in linux, Qt embedded and mini2440, i want to know how can i uninstall qtopia 2.2 from my mini2440? and how can i setup Qt embedded 4.6? i m downloading file from sourceforge.com and i copy that to a Sd card but i don't know what am i doing now exactly? after this i want create my application and boot that in mini2440.how can i add my application in boot? how can i change first image when linux load to my picture? thanks a lot.
thanks davef but i want first now how to uninstall qtopia from my device
I suppose you could remove the line in /etc/init.d/rcS (last line in the factory distro 2.6.32.2) that starts Qtopia and then go to the directory folder where it lives and delete it. I thought you wanted to install 4.6 and when you do that Qtopia 2.2 is gone gone.
thanks a lot, i compile qt 4.6 and i have some errors for some example like this: [sub-plugandpaintplugins-install_subtargets-ordered] Error 2 make[2]: Leaving directory `/home/daniel/Programming/qt-everywhere-opensource-src-4.6.3/examples/tools' you think my compile have a problem or not. thanks again.
Hi again i can make successfully now but i cant make install i have this error arm-none-linux-gnueabi-ranlib: not found how can solve this problem? please help!
ok my problem change to this when i use make install i havent permission to copy file in /usr/local/Qt and so i use sudo make install and now i have this error: /bin/sh: arm-none-linux-gnueabi-ranlib: not found what am i doing now? i export path too. thanks a lot.
Check that it is in the same directory as your compiler, ie arm-2008q3/arm-none-linux-gnueabi/bin/ and another one in arm-2008q3/bin/
yse i have this two folders
arm-none-linux-gnueabi-ranlib is in two directories too
this is some detail of my problem i dont understand /bin/sh make[4]: Entering directory `/home/daniel/Programming/qt-everywhere-opensource-src-4.6.3/examples/tools/plug andpaintplugins/basictools' install -m 644 -p "../../plugandpaint/plugins/libpnp_basictools.a" "/usr/local/Qt/examples/tools/plugandpaint/plugins/libpnp_basictools.a" arm-none-linux-gnueabi-ranlib "/usr/local/Qt/examples/tools/plugandpaint/plugins/libpnp_basictools.a" /bin/sh: arm-none-linux-gnueabi-ranlib: not found make[4]: *** [install_target] Error 127 make[4]: Leaving directory `/home/daniel/Programming/qt-everywhere-opensource-src-4.6.3/examples/tools/plug andpaintplugins/basictools' make[3]: *** [sub-basictools-install_subtargets] Error 2 make[3]: Leaving directory `/home/daniel/Programming/qt-everywhere-opensource-src-4.6.3/examples/tools/plug andpaintplugins' make[2]: *** [sub-plugandpaintplugins-install_subtargets-ordered] Error 2 make[2]: Leaving directory `/home/daniel/Programming/qt-everywhere-opensource-src-4.6.3/examples/tools' make[1]: *** [sub-tools-install_subtargets] Error 2 make[1]: Leaving directory `/home/daniel/Programming/qt-everywhere-opensource-src-4.6.3/examples' make: *** [sub-examples-install_subtargets-ordered] Error 2
ok To solve this do the following: In my case user=daniel, group=daniel, in your case use your go to /usr/local/Qt sudo chown -hR daniel Qt/ sudo chgrp -hR daniel Qt/ Change both user and group of destination directory to your user and group. After that, just execute: make install
i want now copy my file to arm board ,then i copy them to sd card and i want run this export: export TSLIB_TSEVENTTYPE=INPUT export TSLIB_CONSOLEDEVICE=none export TSLIB_FBDEVICE=/dev/fb0 export TSLIB_TSDEVICE=/usr/input/ts export TSLIB_CALIBFILE=/usr/etc/pointercal export TSLIB_CONFFILE=/usr/etc/ts.conf export TSLIB_PLUGINDIR=/usr/lib/ts export LD_LIBRARY_PATH=/sdcard/Qt/lib export QTDIR=/sdcard/Qt export QWS_MOUSE_PROTO=tslib:/usr/input/ts export QWS_DISPLAY=LinuxFB:mmWidth=310:mmHeight=190 but i have this directory with this files: /usr: bin , local, sbin , share /usr/local: bin , etc, lib /usr/local/bin: ts_calibrate (file) /usr/local/etc: ts.conf (file) /usr/local/lib/ts: dejitter.so, input.so, linear.so ,pthres.so ,variance.so my device have 3.5" lcd so i think i must change that to this: export TSLIB_TSEVENTTYPE=INPUT export TSLIB_CONSOLEDEVICE=none export TSLIB_FBDEVICE=/dev/fb0 export TSLIB_TSDEVICE=/usr/local/lib/ts export TSLIB_CALIBFILE=/usr/local/bin export TSLIB_CONFFILE=/usr/local/etc/ts.conf export TSLIB_PLUGINDIR=/usr/local/lib/ts export LD_LIBRARY_PATH=/sdcard/Qt/lib export QTDIR=/sdcard/Qt export QWS_MOUSE_PROTO=tslib:/usr/local/lib/ts export QWS_DISPLAY=LinuxFB:mmWidth=310:mmHeight=190 if i m wrong please correct me, thank you so much.
ok i do everything but nothing happened i use telnet and i execute following lines but when reboot my mini2440 nothing happend and qtopia 2.2 load again please help me.
Danics, Did you remove the last lines in rcS? in the last lines, Qtopia launch. What you need is remove this line and then, by telnet, launch any example. Remember to put the Environment variables so that Qt found the libs. Regards, Mario
thanks mario, i thought Qt4.6 is like qtopia 2.2 and have a Desktop and another application if i m wrong please correct me!
