I just want to make sure I'm not being stupid before I send in a bug.=20
The problem seems to be with gcc when using the pow function in the
math.h library. Here's code that works:
#include <stdio.h>
#include <math.h>
int main()
{
printf("%f\n", pow(2,3));
return 0;
}
Now, the following will not compile:
#include <stdio.h>
#include <math.h>
int main()
{
int x =3D 2; // I tried these as doubles too since the pow function
takes doubles
int y =3D 3;
printf("%f\n", pow(x,y));
return 0;
}
I compiled both programs using:
gcc test.c
The second example gives the following error:
/var/tmp//ccxtkMwv.o(.text+0x45): In function `main':
: undefined reference to `pow'
If I comile with g++, I have no issues. Are these results that I
should have? If so, why? If not, I'm going to submit the bug on gcc
(or the linker, but I'm guessing it's the same group).
Thanks,
Jonathan Herriott
