Create C++ routines in windows

[prasson_ibm]

Hi All,

I have installed datastage 7.5 in my laptop and also installed .net 2003.Here i have created c++ routines and i want to call it in transformer.For that i need to generate object file.But i dont know how to create that object file in windows.

Can anyone help me.


Thanks

Hi,

Can anyone help me in this topic..??

Windows or UNIX, doesn't really matter, the compiler would function the same way in either environment. I don't know the gory details, but an exact search for object file returned 130 matches, something in there should help answer your question.

thanks for your detailed sincere explanation and patience, it is really useful :D

Hi
With the help of mike's post i an finally able to complile the routine,but its not working properly in transformer.
my code is :-

Code: Select all

#include<conio.h>
#include<stdlib.h>
int sum(int a,int b)
{
int c;
c=a+b;
return c;
}

When i am compiling its giving following warning :-

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\stdlib.h(185) : warning C4005: 'errno' : macro redefinition
C:\Program Files\MKS Toolkit\include\nutc\errno.h(32) : see previous definition of 'errno'c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\stdlib.h(428) : warning C4005: 'sys_errlist' : macro redefinition

Object file is created & i copied this file to C:\Ascential\DataStage\PXEngine\lib path but while calling the routine in Transformer its giving below error message:-

Hi All,

Can anyone help me to resovle above mentioned issue.....

1. Is the same macro defined in both your header files? If so you'll need to figure out a way around that.

2. Set PWD to a single dot (current working directory).

3. The "number of datasets" error is sometimes spuriously thrown when the compiler license has expired. This is something else you might check.
