Hey there
I would be obliged if anyone could solve my problem
I have compiled 'myprogram.c' without errors by using 'gcc -c myprogram.c'
Well, when i am trying to link the object code to the executable by using gcc -o myprogram myprogram.o i get the following error:

myprogram.o(.text+0x6f3): In function `fuction1':
: undefined reference to `pow'

The fact is that i have tried to make another program without including <math.h>
and using pow().And finally It worked.
By the way, I am using Slackware Linux(BackTrack) if that matters.

Any ideas?
Thanks for your time.

pass -lm to link in the math library.

Hey again
I am really sorry but i am quite newbie
Could you illustrate me how to do it?

When you link a program using gcc, you specify what libraries to link into your target using the -l switch. gcc will look in common directories for libraries. If you say "-lm" gcc will search for "libm.so" or "libm.a" (depending on other options). libm is the math library, where pow() is defined.

Many thanks for your help
It was really nice of you
