Hi,
I am trying to call a C++ routine in a parellel job in a transformer. But I am getting an error as below. Please some one let me know how to create a C++ function,place it in what folder and how to call it step by step. It will be of great help.

Thanks in advance

I beleive you have some suntax error in your routine ,can you send your routine that will help us to solve the issue.Are you using transformer or basic transformer?

In particular look in and around line 20 of your routine. The error message complains of unexpected characters ".;" - can you see them there?

Hi,
My routine code is very simple as belwo. I am calling this routine in a transformer in a paralle job where i am passing an input column as variable. I am not getting any syntax error in the transformer. I eman no error when validating the stage variable

Below is my c++ routine

#include <iostream>
using namespace std;
int main(int var1)
{
if (var1 >= 1000 && var1 <= 1044)
{
return(0);
else
return(1);
}


}

The name of my routine is libRange.so

The way I am calling the routine is

1. I have created a stage variable say 'X'
2. Then I am calling the routine as libRange.So(<INPUTCOLUMN NAME>)


Regards,
Pavani

HI ray,
I don't see any such characters in my routine. There is only one opening flower brace in that line. There is nothing other than that in that line

This is not a routine but a complete program. Get rid of the main an change it to your function name. Test it out from command line by having a main function. Make sure it works. Then take out the main and compile the function again. Then call it from within datastage.
