Re: [yocto] do_package error after building meta-tensorflow and libcamera-apps does not detect tensorflow-lite

Have you applied all the mentioned changes? The first 2 should be fixed
by the tflite patch[1] (which packages these missing headers).
For the 3rd point there is an extra patch in the github PR[2], which
addresses it. I haven't seen the last error, but the first three at
least should be gone...
