Linux/AM3354: Qt version

HI Margarita,

I observed that the default QT version is same for SDK03.03 (kernel 4.4.41)     and     SDK04.02 (kernel 4.9.59).

I got the QT version when I run the app in evaluation kit with default Linux image of SDK04.02.

Am I doing anything wrong ?

Please find attached images for both the SDKs.

Also can you please suggest how to build only QT (instead of arago-core-tisdk-image) using Yocto ?

SDK 04.04 -->

SDK 03.03 -->

Thanks a lot for your kind support.

Hello Margarita,

I understood why QT_VERSION_STR is 5.6.1

The reason is we are using the qmake of SDK03.01    for SDK 03.03 and SDK04.02 for cross compiling in QT app (in QT creator) --> http:// processors.wiki.ti.com/index.php/File:Sitara_Linux_QT_options.jpeg 

Note: SDK03.01 qmake is of QT 5.6.1 --> Hence I am getting the error

I found we are not able to use qmake of SDK 03.03 or SDK04.02.

t is throwing an error " not able to find gnu/stub-soft.h" if we use SD03.03 or SDK04.02

Query 1:

Can you please let me know if we cross compile QT app using the qmake of SDK04.02 (ti-processor-sdk-linux-am335x-evm-04.02.00.09/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/qt5/qmake), how can we overcome the error in QT ?

Query 2:

I am building QT5.8 using yocto and using processor-sdk-04.02.00.09-config.txt. MOdified follwoing line to get QT5.8

meta-qt5,git://github.com/meta-qt5/meta-qt5.git,master,333949a8239dfa7788b35f1059614733e11a6a25,layers=

However when I do MACHINE=am335x-evm bitbake -k qtbase, I am getting attached error. Need your guidance to fix this.

Hi Margarita,

1) Thanks for the links. However all the posts indicating to use older SDK qmake even though libraries are from newer SDK. Kindly correct me if my understanding is wrong

2) I have successfully built qtbase and qtdeclarative of QT5.8 for SDK 04.02 without any warning/error.Thanks for your support.

Also I have received all libraries under: tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/qtbase/5.8.0+gitAUTOINC+49dc9aa409-r0.arago12/image/usr/lib   (please find below). Please correct me if this path is fine or not for updated QT library.

Queries:

A) Can I just replace all these libraries(QT 5.8) on my BSP created with any SDK (lets say roo filesytem /usr/lib from SDK 03.03 or SDK04.02)

B) How will my QT app know which one to refer if I have both QT5.6 and 5.8 libraries in my filesystem (using soft link ?) ?

C) Now how can I download and install QtWayland (Link: https ://wiki.qt.io/QtWayland) on this  on my BSP? Will Yocto help me on this ?

Just to clarify: I want QtWayland (not Wayland)

Thanks a lot for your guidance.

Br,

Biplab

Hello,

Per my understanding qtwayland is part of qt5.8. And you changed the meta-qt5 so you could try ... bitbake qtwayland is it working on your side.
