Hi Mark,
I have used the 81bab23a4661fdaaa859325d6d3603811ecf1849 version prelink to
build my image.
Prelink run smoothly without output like before, the image is also
modified, so the prelink works.
My application also run correctly. But how can I make sure the prelink take
effect when I start an
executable?
Here attaches the do_rootfs log:
NOTE: ###### Generate images #######
NOTE: Executing mklibs_optimize_image ...
DEBUG: Executing shell function mklibs_optimize_image
DEBUG: Shell function mklibs_optimize_image finished
NOTE: Executing prelink_image ...
DEBUG: Executing shell function prelink_image
Size before prelinking 49340.
Size after prelinking 49592.
DEBUG: Shell function prelink_image finished
Regards,
Qiang
