Undefined reference to pthread_create in Linux

Question

I picked up the following demo off the web from https://computing.llnl.gov/tutorials/pthreads/

#include 
#include 
#define NU         


        

Answer 1

For Linux the correct command is:

gcc -o term term.c -lpthread

1. you have to put -lpthread just after the compile command,this command will tell to the compiler to execute program with pthread.h library.
2. gcc -l links with a library file.Link -l with library name without the lib prefix.
