Re: linking problem with gmp

[Anand Dhanakshirur]

Hello,
Thanks Kevin....
Yes..I am cross compiling on pentium-3 system running redhat linux 8.0 for
the target
processor m68000, The RTOS on m68k is XRTS..What option is should use for
configuring?
That is, What i should give for VENDOR-OS ?

The piece of code i have used is like this...
Process Tester()
{
  Hdr *pMsg;
  Int d = 2;
  char a[10], *s;
  mp_exp_t exp;
  mpf_t x,y,z,p;

  s = a;
  mpf_set_default_prec(32);
  mpf_init_set_d(x,3.5666);
  mpf_init_set_d(y,4.56);
  mpf_mul(z,x,y);
  mpf_floor(p,z);
  s = mpf_get_str(0,&exp,10,7,z);
  printest("%s",s);
  mpf_clear(x);
  mpf_clear(y);
  mpf_clear(z);
  mpf_clear(p);

The linker errors , i am getting are like this..
