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. -JC On Mon, Dec 8, 2014 at 1:52 PM, Qiang Yu <yuq...@gmail.com> wrote: > Thanks for your reply.
