I recommend you to file a bug here https://bugzilla.yoctoproject.org/ if not
done already. You may get a proper answer on armhf support there. From what I
see, (someone please correct me if I am wrong), there is no prelink dynamic link
armhf patch. You can also create and submit the patch for review. AFAIK, you are
gonna need to something like below,
.dynamic_linker = "/lib/ld-linux-armhf.so.3" in arch-arm.c.
This is not tested though. Please do a test yourselves.
See: http://marc.info/?l=fedora-arm&m=135417053128837&w=2
Nobody had requested prelink support for armhf up to this point.
Open an enhancement / bug and assign it to me. I'll do what I can to integrate
the patch officially.
I had been waiting for the prelink upstream to merge this, but they never
bothered to, so I'll have to make it a Yocto Project 'cross-prelink' specific path.

Thanks for your reply. I almost give up.
You mean that current yocto build doesn't support hard float ABI prelink,
and the prelink source code needs to
be modified to use ld-linux-armhf.so.3?
So this problem affect all armhf build of yocto, in other words prelink
doesn't work for yocto armhf at all now?

Hi,
I think it has to do with the ld-linux-armhf.so.3. May be you should
tell prelink that you have hard float ARM ABI to prelink for, than
ld-linux.so.3 . It means you need to add ld-linux-armhf.so.3 as a
dynamic linker.
You should patch the prelink source to get this done.
HTH.

Hi all,
I'm building a image with local.conf:
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
but I think prelink does nothing on my image, because the MD5SUM is
the same before and after
the prelink stage. The mklibs stage is also strange not print
anything. How to make prelink and
mklibs really work?
Here is the log of log.do_rootfs:
