Hi All,

I need to build libunwind on powerpc, however, when i try to build it, I'm facing following errors:

Here's the command i've used to build libunwind:
./configure CFLAGS="-g -O2 -m64 -maltivec" CXXFLAGS="-g -O2 -m64 -maltivec" --build=powerpc64le-unknown-linux-gnu --disable-minidebuginfo --with-pic --prefix=$PREFIX

System details are as follows:
OS: rhel
Arch: ppc64le
gcc version: 4.9.2

Please let me know if you have any pointers on this issue.
