libcxx : simple hello world failed

Clang Frontend

Hi all,

I’m trying to do a simple hello world using libc++ but I got the following link error :

/usr/local/lib/libc++.so: undefined reference to std::__1::locale::locale()' /usr/local/lib/libc++.so: undefined reference to std::__1::num_get<wchar_t, std::__1::istreambuf_iterator<wchar_t, std::__1::char_traits<wchar_t> > >::id’
/usr/local/lib/libc++.so: undefined reference to std::__1::codecvt<char, char, __mbstate_t>::id' /usr/local/lib/libc++.so: undefined reference to std::__1::locale::operator=(std::__1::locale const&)’

/usr/local/lib/libc++.so: undefined reference to `std::__1::ctype<wchar_t>::id’

I use the latest revision of both clang and libc++.

Any ideas ?

Best regards,

Are you linking against libc++ at all?

Any ideas ?

http://llvm.org/svn/llvm-project/libcxx/trunk/src/locale.cpp

Look just below the #include's... I'd guess you're running on something other
than an Apple system?

Looks like "patches welcome".
