Compiling with Clang using Libc++ undefined references

The first couple are too long to reference. I get this error when I try to compile clang++ -stdlib=libc++ ../main.cc ... with clang and libc++ from the SVN.

error: undefined reference to 'typeinfo for char const*'
error: undefined reference to '__cxa_allocate_exception'
error: undefined reference to '__cxa_throw'
/tmp/cc-pbn00y.o:../main.cc:function std::__1::deque<double, std::__1开发者_Go百科::allocator<double> >::__add_back_capacity(): error: undefined reference to '__cxa_begin_catch'
/tmp/cc-pbn00y.o:../main.cc:function std::__1::deque<double, std::__1::allocator<double> >::__add_back_capacity(): error: undefined reference to '__cxa_rethrow'
/tmp/cc-pbn00y.o:../main.cc:function std::__1::deque<double, std::__1::allocator<double> >::__add_back_capacity(): error: undefined reference to '__cxa_end_catch'

SOLUTION: Thanks to one of the answers, I know the solution. libc++ can't be used by itself like libstdc++, it has to be linked along with libc++abi. However, libc++abi isn't complete yet, so using libc++ seems to be a little incomplete for the moment, but it is still my first choice when it completes.

UPDATE 5/26/2012: libc++abi is now complete for C++ and I have been using clang++ as follows successfully clang++ -std=c++11 -stdlib=libc++ -lc++abi.

I believe libc++ doesn't support all exception functions yet. See the status page:

http://libcxxabi.llvm.org/spec.html

You could probably link against gnu's libstdc++

---

Here's what works for me with the Ubuntu Vivid packages for clang and libc++:

clang++ -std=c++11 -stdlib=libc++ <object files> -lc++abi -lsupc++

It is important that the object files come before the -l flags, e.g. when you use exceptions. Obviously, this still will not link if you use libraries compiled against libstdc++ and use any STL types in those interfaces.

---

This seems like you are using exception handling, but it isn't enabled in the compiler. Try passing -fexceptions to the commandline.

I'm only adding this answer as I literally made this mistake just now. It was compiling most of what I was writing just fine for days, but now it starts throwing undefined reference errors...

So... I... sorta possibly was compiling with clang not clang++. Yeah. That was all that was wrong. clang++ includes C++ library stuff, clang doesn't. Oops!
