llvm dev - May 2012 - [LLVMdev] lli unable to resolve symbol _ZNKSt3__16locale9use_facetERNS0_2idE in bitcode

Hi,
   LLVM/Clang version: 3.2svn (r156975). I have a bitcode file that I'm 
trying to load/execute using lli as below but it reports an error about 
unresolved symbol:
> LLVM ERROR: Program used external function
'_ZNKSt3__16locale9use_facetERNS0_2idE' which could not be resolved!

   I've tried loading the following libs when running

Anything missing above? I tried using libstdc++.so.6 as well as its full 
path as above, same error.

Thanks,
Ashok

Resending, any pointers? I demangled the symbol and it turns out to be:
std::__1::locale::use_facet(std::__1::locale::id&) const

tia,

My guess is that you've got a .bc file produced on a mac using libc++ 
(hence the ::_1 part) and you're trying to run it on linux with 
libstdc++ (which doesn't use inline namespaces, the '::_1::' part).
That
won't work.
