Description Qiang Yu 2014-12-10 02:38:20 UTC

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.

Here is the log of log.do_rootfs:

Comment 1 Mark Hatle 2014-12-10 02:59:32 UTC

A test version of the prelink is available in the git repository.

Can you try your test with it, to enable it put the following in your local.conf:

SRCREV_pn-prelink = "2cde4ff118b5244f5577d9bc585c1ee521740af0"

Run the build again and see if the issue goes away (and importantly, that the results boot and execute properly.)

Thanks!

Comment 2 Mark Hatle 2014-12-10 23:11:00 UTC

New version:

SRCREV_pn-prelink = "81bab23a4661fdaaa859325d6d3603811ecf1849"

Fixes non-hf ARM, adds the ld-linux-armhf.so.3 to the ldso list in the prelink-rtld.

Comment 3 Mark Hatle 2015-02-19 16:15:57 UTC

Upstream cross-prelink project is working.  We just need to get the update into oe-core.

Comment 4 Mark Hatle 2015-08-31 14:51:35 UTC

Commit checked in to enable the latest code:

c9e4867a605a8007f569ed6ec4cf445111a533c1

(Note there are some reports of failures with the latest glibc ld-so.  I'd like to track those in a separate defect as I believe it's unrelated to this issue.)
