[Click] log() function

[Philippe De Neve]

Hi all,

I have a question concerning the use of mathematical functions inside click
elements. Concider next function:

void GausJitter::JitterCalculate(uint32_t&  _gap)

{

  float  w;



    w= sqrt ((-2.0 * log(w))/w);



}



When I compile this no errors are returned. But if I want to insmod the
package it returns with "unresolved symbol log".

Now when I remove the log function the compiling and insmod works just fine.
It doesnt have any problem with the sqrt function!



These headers are included:



#include <click/config.h>

#include <math.h>

#include <click/confparse.hh>



What am I missing here?

Tnx for all help!



Philippe.
