**我编写了这个 c 代码,并且我已经安装了一个编写此命令的 pthread 库**sudo apt-get install lpthread-stubs0-dev
#include <stdlib.h>
#include <pthread.h>
#include <stdio.h>
#define NUM_THREADS 5
void *PrintHello(void *threadid)
{
printf("\n%d: Hello World!\n", threadid);
pthread_exit(NULL);
}
int main (int argc, char *argv[])
{
pthread_t threads[NUM_THREADS];
int rc, t;
for(t=0; t<NUM_THREADS; t++)
{
printf("Creating thread %d\n", t);
rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t);
if (rc)
{
printf("ERROR; return code from pthread_create() is %d\n", rc);
exit(-1);
}
}
pthread_exit(NULL);
}

执行以下命令来获取你的程序(我把它放在前列腺素)编译:
sudo apt-get update
sudo apt-get install build-essential
gcc pth.c -lpthread -o pth
然后运行它:
./pth
注意:出于调试目的,请使用gcc pth.c -lpthread --include-directory=/usr/include -o pth --verbose
并将此命令的输出添加到问题正文中。
