linux每日一練：Enable multithreading to use std::thread: Operation not permitted問題解決
在linux在需要使用c++11時會遇到這樣的問題。只要在cmake或者makefile中增加 "-std=c++11 -pthread"
cmake_minimum_required (VERSION 2.6)
PROJECT (threads_tests)
SET(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} "-std=c++11 -pthread")
ADD_EXECUTABLE(threads_1 threads_1.cpp)
