[yocto] prelink & mklibs problem

[Qiang Yu]

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:
