Error trying to build core-image-sato.

[pauldotknopf]

I am trying to build an example image, core-image-sato.

When trying to build, I get this.

It seems that the NVidia libraries provided are only 32bit. Is this correct? What does this layer even support multi-lib then? Why not just compile everything (even then kernel) at 32bit?

[pauldotknopf]

I was able to get it working using bitbake lib32-core-image-sato. However, I am getting some xorg driver errors. Something to do with NVidia not supporting XORG eabi version 20, whatever that means.

Any update on supporting 23.2?

I figured out how to work around the xorg ABI problem after I updated to the 24.1 drop - commit

This may work with the 23.2 base as well.

And yes, you have to use the lib32- prefix to get the 32-bit binaries. For my use, I was mixing 32-bit and 64-bit userland binaries, hence the multilib configuration.

And sorry for not responding to these sooner - turns out I wasn't getting notifications about issues being opened, so I didn't know these were here.

At this point, the L4T R24.1/JetPack 2.2 drop has been integrated, which is fully 64-bit. I'm not planning on supporting 32-bit kernel or userland binaries going forward.
