[Libunwind-devel] undefined reference to `_Uppc64_get_elf_image'

[Jim Galarowicz]

Hi,

I'm trying to build and use libunwind-1.0.1 on ppc64.  However, when I 
try to use the library I'm getting the undefined symbol reference for 
symbol: _Uppc64_get_elf_image.

Would anyone know what the problem might be?   I did an internet search 
and found a reference to _Uppc64_get_elf_image as an undefined in 2007 
with some indication of that particular problem being resolved, but no 
details.

Any help would be greatly appreciated.

Thanks,
Jim G.

This is from the OpenSpeedShop configure to determine if libunwind is 
present and usable.

configure:24170: result: yes
configure:24242: checking for libunwind library and headers

When I had -lunwind before -lunwind-ppc64 I got a similar message:
/home/jeg/OSS201_64/lib64/libunwind.so: undefined reference to 
`_Uppc64_get_elf_image'




When I changed directories  into the src/.libs directory for 
libunwind-1.0.1  I see these references to the `_Uppc64_get_elf_image' 
symbol.
