Subject: Re: [yocto] Problems building eSDK: Exception: variable BBFILES
references itself!

All,

I've used the SDK in the past and want to start using the eSDK for my

project.

I'm on the dunfell branch. I'm trying to build the eSDK for my image
by
calling:

bitbake <my_image_name> -c populate_sdk_ext

The sdk generation fails with the error in the subject. I haven't
been able to find any documentation on what this means or how to fix
it. I've tried deleting my tmp directory and running cleansstate on
my image and I still get the same error. I've also tried generating
the eSDK for core-image-minimal and I have the same error. I can
generate the SDK successfully, just not the eSDK. I have copied more
of the build output below if it helps. Note that I have replaced some
text that I'm paranoid about publishing on the internet; the modified text is

enclosed with <>.

Does anyone have any insight as to why the eSDK build is failing?

Could you share what bitbake -e shows BBFILES as being set to? The variable
history from that command for the variable may also be helpful.

There has to be something different to how you're setting it compared to
what we test on the autobuilder.

Cheers,

Richard

Here's what I was able to pull from bitbake -e. I've included details for both BBFILES and BBFILES_DYNAMIC. Let me know if anything else would be helpful.

Thanks,
Bryan
