Yocto Dunfell Build of t2080rdb fails GLIBC build

[vboroda]

I just got the fresh git pull of Dunfell from the Yocto Project, and the bitbake fails configuring GLIBC.  I am building on Ubuntu 22.04. All patches are definitely applied, including the 0008-fsl-e500-e5500-e6500-603e-fsqrt-implementation.patch

Hello.

It seems that GLIBC package or dependencies is not complete. so configure failed.

Please share the complete process that you are following to build your project to review if there is a mistake or if you may downgrade the Yocto release to build successfully. 

[vboroda]

My process was the same that I follow for other boards that we support. I cloned the Yocto GIT repos, including meta-freescale, then created the build folder, conf files, SOURCE_THIS script. Then I tried to bitbake u-boot-qoriq, which in turn attempted to build GLIBC and failed.

A few years ago, I used to download the Freescale SDK ISO image, and run a script that set everything up, but I am not sure if there is such a thing any more.

I was able to come up with a patch that allowed me to build GLIBC, however. It's very small so I can quote it here:

Which version of SDK are you using?

[vboroda]

I am not using the FreeScale SDK. Just plain vanilla Yocto Dunfell.

We have other boards (non-FreeScale, non-PowerPC), which we support.  Need to be able to build from the same generic Yocto base.

What is the current T2080 SDK version? The last one I worked with was 2.2, several years ago.

[Oswalag]

The latest version supported by NXP is QorIQ SDK v2.0-1703.
