Hi Tannyveer, It seems me that you try to perform all Qt5 building steps on the target (udoo board). Correct me if I'm wrong. But in the tutorial, it is written: "We will perform the following Qt5 building steps below on the host machine (from 1 to 8 steps)." perhaps it was not clear that host machine means PC desktop or laptop. Can you give me "./configure" command with all options you use. Regards, Nat
Thank U Nat, For given me much important information .Sorry I am not seeing this line on Qt5 tut Yep I did all the steps on udoo boars my configure command is ./configure -prefix /opt/qt5 -make libs -no-pch -no-opengl -device imx6 -device-option CROSS_COMPILE=/home/ubuntu/Qt5_build/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- -no-largefile -opengl es2 -qt-zlib -qt-libpng -qt-libjpeg -no-nis -no-cups -gui -make examples -sysroot /media/tanny -no-gcc-sysroot -opensource -confirm-license -qreal float -v Thank U Once again right now iam starting the steps on host machine
Hi Nat I am running some of the qt3d examples on my udoo but after running udoo board is hangout. that is the problem I faced now, Another one is i want to develop my own qt application on my udoo board using qt creator please tell me the procedure to build my own application on my udoo board.
Hi Tannyveer, It it is quite possible that some of the examples can hangout the board running (for me these examples - "positional_lighting", "robo_bounce", "tea_service"), and there could be different reasons for it (also Qt bugs). If you are interesting in it, you can run "export QT_DEBUG_PLUGINS=1" from your terminal emulator before running an example, to get a debug prompt. You can start to create on the host machine a simple app (project) from this link: http://qt-project.org/doc/qt-5/qtexampl ... rials.html After, you have to cross-compile the source of your project (always on the host machine): $ cd /path/to your project/directory $ /path/to qt5/qtbase/bin/qmake $ make Note : that you must have your sysroot present while cross-compilation (if you have had it under /media directory) If everything worked fine you can try it on your udoo board after have copied your project with project binary file.
Hai Nat Thank U once again for tour nice posting which is very helpful to run my project, Now I run my first Qt widget program on udoo board but program leads to hangout the board i dont know why this be happend, i am unable to debug the code please tell me why its happend and I can write the simple Qt widget program when i touch the push button (even mouse also not working on the widget ) it display the Message on line edit. Awaiting your reply
Hi Tannyveer, To have the permission to access the input devices under /dev/input/ you have to login as root. So do login: root password: ubuntu At least the mouse on your app running must work (I do hope). Make this test first.
Hi NAT, Thank very much for your contribution on my work. Right now I am successfully compile the led's application on my udoo board. Both Mouse and touch panel are working on my Led's app. but one thing is still problem is there when i close the application the gui window is hanged out. I am not getridoff this problem occur still now. (I ran the led's app by taking the root permission )
Hi Tannyveer, It is not clear to me what happens when you close your app... Can you get back to the terminal command prompt after closing the app? If you mean the problem like this one https://qt-project.org/forums/viewthread/41236 It seems quite difficult to find simple solution for this Qt build configuration.
This is the third thread with the same problem while closing qt programs. At the following link there are two possible workarounds: post8312.html#p8312 I hope it can help until someone finds a real solution
