Hello Anu,
Please refer to the following link: https://dev.ti.com/tirex/content/linux-academy-AM62X-8.6.0.42.v1/ch-develop/dev-gpu-porting-guide.html. It's a good starting point for compiling qt5 application and running on AM62 SK EVM.

Krunal
Hi,
I am not able to QT5 build the source code, which was given to me to be flashed on AM62x board. Kindly help me to resolve the issue. Thanks in advance.
1) I followed the below links to install QT5 and set the cross-compilation path for AM62x.
https://vitux.com/compiling-your-first-qt-program-in-ubuntu/
2) Then I followed the steps mentioned in the link to create a sample helloworld program.
[linux-devkit]:~/ti-processor-sdk-linux-am62xx-evm-08.06.00.42/example-applications> cd helloworld/
[linux-devkit]:~/ti-processor-sdk-linux-am62xx-evm-08.06.00.42/example-applications/helloworld> make

[linux-devkit]:~/ti-processor-sdk-linux-am62xx-evm-08.06.00.42/example-applications/helloworld> ls
helloworld helloworld.cpp helloworld.o helloworld.pro Makefile
3) I was successfully able to create the executable file helloworld which can be run on the AM62x EVM board.
4) Now I did the following steps to build my source code, which needs to be cross-compiled for AM62x board.
[linux-devkit]:~/ti-processor-sdk-linux-am62xx-evm-08.06.00.42/example-applications/Peristaltic> ls

5) This is the Peristaltic.pro file which was already available in src.I tried to do cross-compile.

[linux-devkit]:~/ti-processor-sdk-linux-am62xx-evm-08.06.00.42/example-applications/Peristaltic/src> sudo qmake Peristaltic.pro
Project ERROR: Unknown module(s) in QT: declarative
6) Because of the this error. I removed the declarative library from the Peristaltic.pro file, which will be in line "QT += declarative"
7) Again I run the qmake.
[linux-devkit]:~/ti-processor-sdk-linux-am62xx-evm-08.06.00.42/example-applications/Peristaltic/src> sudo qmake Peristaltic.pro

Then I got the below error along with the build log.

Hello,
The OpenCV libs are not present in the default linux-devkit. Based on my internal discussion, our next 9.0 release should include all the opencv libs. The release should be coming out in the next couple of weeks.

Krunal
Hello Krunal,
>> I am have already installed the opencv libraries using "sudo apt-get install libopencv-dev" before the build.

Hello Anu,
Whether Qt version 5.14.2 supports declarative?
--> You need to check with the Qt community on that and we did not develop or design Qt5.14.2.
