Rebuilding the X-LINUX-QT starter package failed due to an incorrect path (/usr/usr/bin/env) in cbortag.py.

[LeonSu]

Hello everyone !

device: STM32MP257F-DK

We build the X-LINUX-QT starter package following in steps
1.X-LINUX-QT starter package

repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11

repo sync

2.Install X-LINUX-QT distribution package v2.2.0

 git clone -b v2.2.0 https://github.com/STMicroelectronics/meta-st-x-linux-qt.git layers/meta-st/meta-st-x-linux-qt

 git clone -b 6.8.3 https://code.qt.io/yocto/meta-qt6.git layers/meta-qt6

3.Setup the build environment

DISTRO=openstlinux-weston MACHINE=stm32mp2 BSP_DEPENDENCY="layers/meta-qt6 layers/meta-st/meta-st-x-linux-qt" source layers/meta-st/scripts/envsetup.sh

4.building

 bitbake st-image-qt package-index

then, we have an error message as follows:

All cbortag.py files in the package were updated, replacing /usr/usr/bin/env with /usr/bin/env, as follows:

However, we encountered the same error message. Could anyone provide us with some suggestions? Thank you in advance.

 

 

 

 

[LeonSu]

We discovered the bug in the qtbase_git.bb file between lines 202 and 203. 

If /usr/bin/env already exists, it will become /usr/usr/bin/env. Therefore, we marked lines 202–203 in the qtbase_git.bb file. This time, the build completed successfully.

[PPAGE.13]

I also had to do the same on my side and commented qt_base_git.bb lines.
There is an issue in Qt build mechanism. This could be pointed out to Qt support.
I don't have today a clean solution.

[PPAGE.13]

Please use this patch over "meta-st-x-linux-qt" layer.

I am going to update github branches.

BR,

Philippe.
