Perhaps I'm mistaken? I did some research and I'm confused.. aarch64 is screwed up by consensus apparently.. Dynamic libraries live in /lib64, and the dynamic linker in /lib.. Whee! So ya, this patch isn't correct.. the dynamic linker needs to stay in /lib. (Nothing says you can't sym/hardlink to lib64.. but it has to refer to in in /lib for the ABI conformance.) --Mark > --Mark > >>> >>> Signed-off-by: Kai Kang >>> --- >>> meta/recipes-devtools/gcc/gcc-4.9.inc | 1 + >>> .../0056-redefine-dynamic-linker-for-aarch64.patch | 34 ++++++++++++++++++++++ >>> 2 files changed, 35 insertions(+) >>> create mode 100644 meta/recipes-devtools/gcc/gcc-4.9/0056-redefine-dynamic-linker-for-aarch64.patch >>> >>> diff --git a/meta/recipes-devtools/gcc/gcc-4.9.inc b/meta/recipes-devtools/gcc/gcc-4.9.inc >>> index 25778bd..c434a45 100644 >>> --- a/meta/recipes-devtools/gcc/gcc-4.9.inc >>> +++ b/meta/recipes-devtools/gcc/gcc-4.9.inc >>> @@ -70,6 +70,7 @@ SRC_URI = "\ >>> file://0053-gcc-fix-segfault-from-calling-free-on-non-malloc-d-a.patch \ >>> file://0054-gcc-Makefile.in-fix-parallel-building-failure.patch \ >>> file://0055-PR-rtl-optimization-61801.patch \ >>> + file://0056-redefine-dynamic-linker-for-aarch64.patch \ >>> " >>> SRC_URI[md5sum] = "fddf71348546af523353bd43d34919c1" >>> SRC_URI[sha256sum] = "d334781a124ada6f38e63b545e2a3b8c2183049515a1abab6d513f109f1d717e" >>> diff --git a/meta/recipes-devtools/gcc/gcc-4.9/0056-redefine-dynamic-linker-for-aarch64.patch b/meta/recipes-devtools/gcc/gcc-4.9/0056-redefine-dynamic-linker-for-aarch64.patch >>> new file mode 100644 >>> index 0000000..6933e2f >>> --- /dev/null >>> +++ b/meta/recipes-devtools/gcc/gcc-4.9/0056-redefine-dynamic-linker-for-aarch64.patch >>> @@ -0,0 +1,34 @@ >>> +From 8fbb60d89e569b68b13e4fd419e20640eb49cabc Mon Sep 17 00:00:00 2001 >>> +From: Kai Kang >>> +Date: Tue, 16 Sep 2014 16:01:31 +0800 >>> +Subject: [PATCH] Redefine dynamic linker for aarch64 >>> + >>> +Redefine dynamic linker for aarch64 from /lib to /lib64. >>> + >>> +BASELIB of aarch64 has to be defined with 'lib64', then linker file >>> +ld-linux-aarch64.so.1 is installed into /lib64 rather than /lib.
