Pthread.h undefined reference to ' pthread_create '

to add-lpthread or-pthread parameters in the compilation (different versions of GCC may not be the same, man GCC can refer to the corresponding parameters).

For example, to execute the PTHREAD.C file after adding the header file # include <pthread.h>, you need to use the following command:

Gcc-lpthread-o Thread THREAD.C

Or

Gcc-pthread-o Thread THREAD.C

This situation is similar to the use of <math.h>, which needs to be added to the-m parameter at compile time.
