undefined reference to `pow' collect2: ld returned 1 exit status

In Linux GCC compiler when we compile a c program may get error message:

Error message: undefined reference to `pow' collect2: ld returned 1 exit status

Compiler: Linux gcc

Solution:

Cause of this error is by default math.h library has not included. So compile the c code in following way:

[root@localhost ~]# gcc abc.c -lm

Note: Here abc.c is name of any c code file.
