C DPI compilation error

abhingp01

Hi all,

 I am checking my OVC against existing eVC. My OVC has some DPI interfaces with C-code.

 C-Code is as follows:

#include<math.h>
#include"svdpi.h"

int ilog2_inC(int val)
{
   return (log2(val));
}


int ipow_inC(int val)
{
   return(pow(2,val));
}

I am using it in my monitor class of OVC.

Following statements imports it:

import "DPI-C" pure function int ilog2_inC(int logchk);
import "DPI-C" pure function int ipow_inC(int logchk);

 But on compiling I am getting following error:

ncsim: *F,NOLWSV: Unable to load the default library libdpi.
OSDLERROR: ./libdpi.so: cannot open shared object file: No such file or directory or file is not valid ELFCLASS32 library..

 

Kindly help for same.

 

Regards

Abhishek
