Qt cross compile for SDR board

[Mijaz]

I have cross compiled executable file from QT 4.8.7 and i am running it on SDR ADRV9361 board (Linaro-Ubuntu). When i run the cross compiled executable file (which is cross compiled on Ubuntu 16.04) on my SDR board, i got the error message like : " symbol lookup error : ./project: undefined symbol: _ZN7QWidget8qwsEventEP8QWSEvent". I don't know why i am getting this error as I conformed tool chain version on both side, please help.

I followed following forums:

@Mijaz said in Qt cross compile for SDR board:

symbol lookup error : ./project: undefined symbol

could you please show output of this command run in your SDR device:

ldd ./your-cross-compiled-app

Hi,

Did you deploy your cross-compiled Qt on the board ?
If not, then your application is likely picking the boards distribution provided Qt which is not a Qt for Embedded Linux build.

Hi @Pablo-J-Rogina
Thanks for responding,
Here is the output of your sagusted command:
ldd ./my_ Project

@Mijaz For the future it would be better to post the text output of the command instead of a picture taken from the display.
Just mark the text with your mouse, right click on it and copy.

It shows that your distribution Qt is found, not the one you cross-compiled. So again, did you copy the cross-compiled version of Qt over to the target ?
If so from where to where exactly ?

Hi
please mark the post as solved using the
"Topic Tools " button on top post.

Also if possible, can you write what you did to make it work ?

@Mijaz
The x11Event Error was just due to the confliction of my deployed project to ubuntu GUI of the target.
Now I just open my project in by the following step:

1. (Cntrl+Alt+F1)
2. Go to your directory where you deployed your project
   3 ./project -qws
   now your project window comes out and ready for operations.
