[Libunwind-devel] libunwind compile error for ARM64

[Hou Pengyang]

hi, when compiling libunwind for ARM64, there are errors like this:

../src/.libs/libunwind-aarch64.a(elf64.o): In function 
`_Uelf64_get_proc_name':
libunwind/src/elfxx.c:349: undefined reference to `_Uaarch64_get_elf_image'

if anyone has a solution to this problem?
my corross compiler is aarch-linux-gnu-gcc 4.9.2 and libunwind is the 
latest version. My build steps:
# autorefconf -i
# ./configure --host=aarch64 CC=aarch64-linux-gnu-gcc 
LDFLAGS="-L$PWD/src/.libs"
# make

I wonder if I have a wrong configure, the same errors occur when I 
compile libunwind for ARM.

thanks!
