многопоточность — потоки C ++ 11 с лязгом

Я хотел научиться использовать потоки C ++ 11 для ускорения компиляции моего языка (да, я собираю компилятор: x). Первый пример, который я попробовал, бросил несколько ошибок с помощью clang (3.3 SVN). Отлично скомпилировано в GCC (4.6.3).

Я загрузил clang и libc ++ из SVN сайта llvm.org. clang был скомпилирован с GCC (4.6.3), а libc ++ был скомпилирован с clang. Оба make-файла были созданы с помощью CMake.

Для лязга я следовал этому руководству: http://llvm.org/docs/GettingStarted.html#checkout

Для libc ++ я следовал этому руководству: http://libcxx.llvm.org/

Кусок кода, который я хочу скомпилировать (foobar.cpp):

#include <iostream>
#include <thread>

using namespace std;

int main(void) {
thread t1([](void)->void {
cout << "foobar" << endl;
});
}

Компилируется нормально с clang --std=c++0x -stdlib=libc++ -lpthread foobar.cpp но я получаю много ошибок компоновщика:

clang-3: error: linker command failed with exit code 1 (use -v to see invocation)

Вот стандартные каталоги поиска в двух стандартных библиотеках.
В результате ‘clang -Wp, -v -x c ++ — -fsyntax-only’ я получил это:

Я старался clang --std=c++11 -stdlib=libc++ -llibc++ -lpthread -o foobar foobar.cpp но компоновщик снова не удалось, он не находит libc ++. Мне не удается связаться с libc ++ или это что-то более сложное?
