[Llvm-bgq-discuss] linker errors with llvm/current/bin/bgclang++

[Geoffrey Irving]

I'm trying to get my C++11 app running on vesta.  Compiling with clang
gives me the following linker errors (summarized below, with full
build output attached):

/home/projects/llvm/current/bin/bgclang++ -o

clang: error: linker command failed with exit code 1 (use -v to see invocation)
scons: *** [build/powerpc/release/core/libother_core.so] Error 1

Any ideas what might be going wrong?  A google search turned up many
similar bugs in the past, but I haven't found a specific reference.
Notes:

1. The only library I'm linking to is Python.
2. I needed to undef __GXX_EXPERIMENTAL_CXX0X__ in order to get
-std=c++0x to compile.  Otherwise it complains about stuff like this
(more details on request):

/bgsys/drivers/ppcfloor/gnu-linux/powerpc64-bgq-linux/include/c++/4.4.6/bits/stl_pair.h:106:10:
error: no matching function for call to 'move'
        : first(std::move(__p.first)),
                ^~~~~~~~~

Thanks,
Geoffrey
