Qt cross compile for Raspbian Jessie
-
Are you sure
/mnt/rasp-pi-rootfs/usr/local/qt5pi/includeis accessible ? -
jsondb and jsbackend ? Where did you had them ?
Can you locate qwidget.h in
/mnt/rasp-pi-rootfs/usr/local/qt5pi/include? -
Looks like it, what option did you give to configure ?
-
@SGaist ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi
same as mentioned in http://wiki.qt.io/Raspberrypi_beginners_guide -
That looks correct, do you have the configure summary ?
-

Looks good…
Might be a glitch when you ran
make install -
Well, basically and if I understood you correctly, you are able to cross-compile without any problem, correct ? When calling
make installdid you have the root file system of the Pi mounted correctly ? -

But after finishing installation i m getting only QtConcurrent, QtCore, QtDBus, QtGui, QtNetwork , QtPositioning, QtScript, QtSensors, QtSql , QtXml , QtXmlPatterns folders in my install and similar in lib directory. So it cant install QtWidget, QtPlateformHeaders, QtPlateformSupport, QtTest, QtOpenGL, QtPrintSupport modules. I did nt find anything unusual in log.
-
Did you build only qtbase or all of Qt ?
-
well according to https://wiki.qt.io/RaspberryPi_Beginners_Guide i have to build and install qtbase and than other modules. So I could not finish this step and I am blocked.
-
That's correct. Do you have libQtWidget.so somewhere in your build folder ?

That one's really puzzling…
What happens if you call
make -C src/widgetsin your builder ? -
Hi @SGaist ,
I dont know what exactly was the problem. But I re cloned repo and than tried all steps and it works as expected. Could be a problem of broken download. But it neither gave me any unexpected error message not it failed. :P
But now i m happy tht i wll have kernel 4.1 with qt in my pi.. thanks for your time and support man. -
Well, that was a good idea !
You're welcome !
