The Ubunto freeze when compiling OpenCV.

Try Bitbake OpenCV -c clean all and than Bitbake OpenCV and after 28% compile process , the OS ubunto freeze after a while, sometimes for more than a few hours till release..

Note: Bitbake core-image-minmal successfully build

Please kindly advise what could be the reason that cause Ubunto stop/freeze during OpenCV compile tasks.

Hello,

I resolve this issue by extending  Ubuntu RAM size.

Hello Uri,

This look more like ubuntu issue, have you try ubuntu 16.04? however we have also observed that you have used '-k' flag with the bitbake. It will continue with the compilation if any task gets failed and so sometimes due to the dependencies between the package another package might fail in the compilation. We have also observed that may be one of the packages is having trouble in fetching and then successfully fetched and issue in the compilation task. So complete clean-up or fresh build without '-k' will resolve the issue.

Regards

Hello,

Thanks for your reply.

I first try build it via Ubunto 20 and it failed, since i got warning on this Ubunto version not tested yet by NXP Yocto. Switched Now to Ubunto 16 and i got similar failed.

BTW, I didn't Bitbake with -k, It might be internal component that have the '-k', Please let me know how to modify it. to build without '-k'.

And please kindly advise what cause the build to failed.

Thanks, Uri

Hello support team,

Please reply how to build correctly the OpenCV or please guide me how to exclude the OPENCV component from the build imx-image-multimedia.

This component always failed during compilation.
opencv           :4.1.2.imx-r0

Thanks, Uri
