GOOD NEWS: You don't need to install any other libraries because pthread library is pre-installed in your ubuntu version

Here we have a simple helloword.c program for you to try compiling programs using pthread library:

#include <stdio.h>
#include <pthread.h>

void * hello(void *input) {
    printf("%s\n", (char *)input);

int main(void) {
    pthread_t tid;
    pthread_create(&tid, NULL, hello, "hello world");
    pthread_join(tid, NULL);
    return 0;
  • Be sure to add #include <pthread.h> if you want to use pthread functions you learned in lecture
  • To compile programs: gcc -o helloworld helloworld.c -lpthread
  • To test your program: ./helloworld
  • Now you can get your hands dirty: why not try programs you learn in the lecture?
