Dear Sir,
I just read your book(Red Hat Linux unleashed, Second Edition) and I 'm not familiar
with Linux operating system. Today I write a very simple program with C language,
but it unsucessed when I compile it. The program script is at following:
#include <stdio.h>
#include <math.h>
main()
{
int i;
double x;
for(i=0;i<5;i++) {
x=double(i);
x=sin(x);
printf( "sin(%d)=%f\t",i,x);
}
}
and the compiler's information is: /tmp/ccBMA1Cj.o: In function 'main':
/tmp/ccBMA1Cj.o(.text+0x48):
undefined reference to 'sin'
collect2: ld return 1 exist status.
Could you tell me why? By the way, could you tell me how to get documents of gcc
compiler programmer's guide ?
Thank you!
G.B.Zhou
