warning: return type of �main� is not �int�

When we will compile a c program we may get following error message:



warning: return type of �main� is not �int�



Solution:



Cause of this warning message is return type of main function is not int. It is necessary to return an int value by main function. If main function returns 0 then operating system treat it as success.



For example:



int main(){

//Write your c code.

}

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

When we will compile a c program in Linux GCC compiler we may get error message:

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

Cause of this error is by default math.h library has not included.

Solution:

Compile the c code in the following way:

[root@localhost ~]# gcc abc.c -lm

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

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.
