Android 12.1.0_1.0.0 build failed for imx8mp

[eric_bentley]

I have an Ubuntu server that I use to build images for the imx8mp for Android versions 9-14. With the exception of Android 12, they all build correct images.  Android 12, however, fails when trying to build the kernel (full log file attached) but I have not been able to resolve.

 I have verified CLANG/AARCH64 and pahole versions are as specified in the Android 12 User's guide:

I've seen some hits with google regarding this kernel but nothing I've been able to use to resolve the issue.  

Thanks for any guidance you can provide.

PS: make invoked with:
./imx-make.sh kernel -j40 |& tee build-`date +%F-%T`.txt
which created a build log with timestamp in the name.  However, this forum would not allow me to upload the file with that name.

This looks like an issue with incompatible tools.  I created a VM with Ubuntu 18.04, installed the tools per the user's guide, and everything builds correctly.

Hello,

Are you working with kernel form NXP since it looks like a kernel issue, you can download from:

https://www.nxp.com/design/design-center/software/embedded-software/i-mx-software/android-automotive...

Regards

[eric_bentley]

this is the kernel that is downloaded by the default command:

source ~/projects/nxp/imx-android-12.1.0_1.0.0/imx_android_setup.sh

I have made zero modifications.  Just trying to build the default image.
