PROCESSOR-SDK-AM62X: Am62x cross compiling QT Application

Hello,

What SDK are you using and do you see the qmake executable in your linux devkit?

Regards,
Krunal

Hi Krunal,

Thanks for the quick reply..

I am using the latest sdk for Am62x : Version : 08.05.00.21

i can able to see the qmake file in the path mentioned below :

$  ti-processor-sdk-linux/linux-devkit/sysroots/x86_64-arago-linux/usr/bin

Hi Murali,

I am not able to replicate the issue on my side. I downloaded the SDK 08.05.00.21 and I am able to compile the project. Here is an example:

Hi Krunal,

Thanks for the response..

I can't able to find any solution for these. i am just tried installing the ti-processor sdk on another machine with Ubuntu 18.04.6 LTS and tried to solve the issue.but i couldn't. the same problem exist.

i have attached the image file for your reference.kindly check and let me know your feedback.

and also i have gone through one of your forum query which is under same issue, there also no solution found.

Hello,

Could you try the following commands:

I have only seen the bash errors when you try running a 32bit binary on a 64bit platform and you are missing certain libraries. I do not think that's the case here but worth checking. On my setup, I have tried various machines and cannot replicate the above issue.

Hi krunal,

kindly find the output of the listed commands.

I don't know why this is happening, i tried it on 3 different systems, with ubuntu 18.04 installation. same issues persists on all the 3 machines. i don't know how to proceed on this.

Hello,

There is a linux-devkit.sh file and I am wondering if you could try running that to see if it helps with the issue.

Regards,
Krunal

Hi krunal,

Thanks that helped.

The linux-devkit.sh file creates one more setup file inside /usr/local/arago-2021.09/environment-setup.

Sourcing this path, helped me to build the Qt Applications.

source /usr/local/arago-2021.09/environment-setup

Thanks&Regards,

Murali C

Hi krunal,

I have just built the hello_world QT application is as follows.

murali@Murali:~/Qt_Wrkspc/hello_world$ source /usr/local/arago-2021.09/environment-setup

[linux-devkit]:~/Qt_Wrkspc/hello_world> qmake hello_world.pro

[linux-devkit]:~/Qt_Wrkspc/hello_world> make

The Output of the file is:

[linux-devkit]:~/Qt_Wrkspc/hello_world> file hello_world
hello_world: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, with debug_info, not stripped

After that i copied the file to the file system, then i tried to run the following file inside filesystem.

root@am62xx-evm:/home# ./hello_world --platform wayland                                                                                       
qt.qpa.wayland: "wl-shell" is a deprecated shell extension, prefer using "xdg-shell-v6" or "xdg-shell" if supported by the compositor by settN

Failed to move cursor on screen HDMI1: -13
qt.qpa.input: xkbcommon not available, not performing key mapping

Could not queue DRM page flip on screen HDMI1 (Permission denied)

I cant able to see the expected output on the HDMI Display. can you please review if anything is missing from side,to display the simple Qt application on HDMI Display.

And also is there any document, how exactly the QT framework works on the SDK. if yes kindly guide me through the exact DOCUMENTATION.

Regards,

Murali C
