Hello.
I am trying to compile the following code
1 #include <stdio.h>
2 #include <math.h>
3 int main (){
4 double a = 0.0;
5 double b = pow (10,a);
6 return 1;
7 }
while I was given the following error message
caojun@ubuntu:~/homework$ gcc -o test.out utility.c
/tmp/ccOQV3cx.o: In function `main':
utility.c:(.text+0x27): undefined reference to `pow'
collect2: ld returned 1 exit status
My gcc pakages
gcc-4.1
gcc-4.1-multilib
gcc-4.2
Can anyone help me please?
Sincerely
Cao Jun
