나는 OSX에 kenlm 컴파일 싶지만 오류를 얻고있다 :컴파일러가 -std = C++ 11로 호출되었지만 std :: move가 정의되지 않은 이유는 무엇입니까?
error: no member named 'move' in namespace 'std'

'-std=c++11'
컴파일하는 것이 좋습니다하지만 난 여전히 같은 오류를 얻고있다. 이 문제를 어떻게 해결할 수 있습니까?
g++ --version

kenlm의 빌드 스크립트는 다음과 같습니다
from setuptools import setup, Extension
import glob

import os
#Does gcc compile with this header and library?
def compile_test(header, library):
dummy_path = os.path.join(os.path.dirname(__file__), "dummy")

return os.system(command) == 0
