CMakeLists.txt编译不正确

以下是运行时报错:
terminate called after throwing an instance of 'std::system_error'
what(): Enable multithreading to use std::thread: Operation not permitted
Aborted (core dumped)


以下是子目录CMakeLists.txt文件:

g++ -std=c++11 -pthread test.cpp -o run 类似这样的编译是没有问题的

[ztenv]

声明一个支持多线程的宏，有相应的声明语法。

class MyThread : public std::thread { public: MyThread() : thread(){} template<typename T, typename...Args> MyThread(T&&func, Args&&...args) : std::thread(std::forward<T>(func), std::forward<Args>(args)...) { } void showcmd(const char* str); //注释掉就错 }; void MyThread::showcmd(const char* str) { system(str); } int main() { MyThread th1([](){ std::cout << "hello" << std::endl; }); th1.showcmd("du -sh *"); th1.detach(); return 0; }
