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

Both answers to this question so far are incorrect.
For Linux the correct command is:

gcc -pthread -o term term.c

In general, libraries should follow sources and objects on command line, and -lpthread is not an "option", it's a library specification. On a system with only libpthread.a installed,

gcc -lpthread ...

will fail to link.
