on my linux machine I'll get errors and i don't know why..

printf("%f", sqrt(10.0));
return (0);
}
this is the error:

I was writing a simple program in linux, which includes sqrt function of c.
I included the math.h. But when I use gcc to compile it, it gave an error message:
/home/murat/tmp/ccOv9upo.o(.text+0x4b): In function `main':
: undefined reference to `sqrt'

Hi,

#!/bin/bash
a=3
b=9
let "c= b*a"
let "d=sqrt $c "
echo $d
But when i execute the code, it gives me the an error saying:

Can any body tell me what I'm doing wrong? (5 Replies)
Guys,
May i know how can we de reference the code reference variable.?
my $a = sub{$a=shift;$b=shift;print "SUM:",($a+$b),"\n";};
print $a->(4,5);
How can we print the whole function ?
Please suggest me regarding this.
Thanks for your time :)
Cheers,

I would like to compile a binary that doesnot depend on LD_LIBRARY_PATH as this binary will be setuid to owner and used by other users and since setuid doesnot support LD_LIBRARY_PATH making it independent of LD_LIBRARY_PATH would be great.

sqrtf
SQRT(3) Linux Programmer's Manual SQRT(3)NAME
sqrt, sqrtf, sqrtl - square root function
SYNOPSIS
#include <math.h>
double sqrt(double x);
float sqrtf(float x);
long double sqrtl(long double x);
Link with -lm.
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
sqrtf(), sqrtl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE; or cc -std=c99
DESCRIPTION
The sqrt() function returns the nonnegative square root of x.
RETURN VALUE
On success, these functions return the square root of x.
If x is a NaN, a NaN is returned.
If x is +0 (-0), +0 (-0) is returned.
If x is positive infinity, positive infinity is returned.
If x is less than -0, a domain error occurs, and a NaN is returned.
ERRORS
See math_error(7) for information on how to determine whether an error has occurred when calling these functions.
The following errors can occur:
Domain error: x less than -0
errno is set to EDOM. An invalid floating-point exception (FE_INVALID) is raised.
CONFORMING TO
C99, POSIX.1-2001. The variant returning double also conforms to SVr4, 4.3BSD, C89.
