(1)std::thread线程函数中可以直接改变类的成员变量,但是不是立马就可以改变,如果主线程过快退出,会造成类的成员变量无法改变的假象。这样你就入坑了,怎么也找不到变量为啥是0的原因。
std::thread *t1 = new std::thread((&test_mutex)); threadlist.push_back(t1); } for(std::list<std::thread*>::const_iterator i = threadlist.begin(); i != threadlist.end(); i++ ) { (*i)->join(); } clock_t finish = clock(); printf("result:%d\n", total1); printf("c...

问题解决过程 因为thread和mutex是C++11才引入的,所以一开始考虑的是不是CMakeList上没有加编译选项,于是加上set(CMAKE_CXX_FLAGS$ {CMAKE_CXX_FLAGS} -std = c ++ 11)经过一番尝试,发现并无效果。 后来受到博客CLion安装mingw并配置以支持c++11多线程编程的启发,重新安装mingw编译器,但是不成功。 又看到博客...
