sin-function from math.h not available

[Matthias Pfeifer]

hi group,

i realy wonder if there is a sin(double) function defined in math.h since
i have problems compiling the following small programm:

/* sinus.c example code */

#include<math.h >

int main(int argc, char* argv[])
{
sin(1.2);
return 0;
}

compiler is gcc-Version 3.3.4 (Debian 1:3.3.4-3) and compilation gives:
matthias@euler: ~/src$ gcc -o sinus sinus.c
/tmp/ccqsY2qP.o(.tex t+0x1a): In function `main':
: undefined reference to `sin'
collect2: ld returned 1 exit status

thank you all.

Yes. Please read the FAQ. You have a linker problem (missing library).

Please note that the is no function defined in <math.h>. It only
containts the functions prototypes.

Of course there is. And your question is well answered in the FAQ, the
checking of which is normal for civilized folk. And don't bother crying
that you don't know where the FAQ is. Expected usenet behavior is to
lurk in a group before posting or at least to check the archives. Had
you done that, you would have seen not only references to the FAQ
location but the FAQ itself.
