Hi,
with cross-built libunwind HEAD (59328832f7ee48682fcd0fd1ca0cb9cfdb32ec4a)
./configure --target=ia64-linux
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... ia64-unknown-linux-gnu
I get:
[GDB failed to load libunwind-ia64.so.8: .../libunwind-ia64.so.8: undefined
symbol: _Uelf64_valid_object]
lobunwind installs in such case only libunwind-ia64.so* and nothing else where
valid_object is missing.
Thanks,
Jan
Move valid_object definition from src/elfxx.c to src/elfxx.h.
Remove its declaration in src/elfxx.h.
