Transformer Compilation Error

[Pavani_Vithala]

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?

[ray.wurlod]

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

Rgds,

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.
