如何在Linux/gcc上创建与pthreads和libstdc ++静态链接的共享对象？

#include<iostream>
#include <pthread.h>
#include <unistd.h>

using namespace std;

void* printHello(void* arg) {
    cout << "Hello from pthread!"<< endl;
    return NULL;
}

int main() {
    pthread_t thread;
    pthread_create(&thread, NULL, printHello, NULL);
    pthread_join(thread, NULL);
    return 0;
}

g++ -c example.cpp -o example.o -pthread -static-libstdc++

g++ -shared example.o -o example.so -pthread -static-libstdc++
