Parallel Routine

opdas · Post by **opdas** » Tue May 30, 2006 5:04 am

Hi,
I have a C function (BinaryToDecimal()) which converts binary input into Decimal.
As we are working on AIX , we created the object file by using Visual Age C++ default compiler by the following command:

xlc -c binarytodecimal.c -o binarytodecimal.o

Then using the object file binarytodecimal.o in the Parallel routine.

But geting the following runtime error:

Transformer_0: Failed to load the library "V0S0_BinaryToDecimal_Transformer_0.o"; either the directory containing the library file
is not on the library search path, or the library was compiled on a system
that is incompatible with this system: Could not load "V0S0_BinaryToDecimal_Transformer_0": rtld: 0712-001 Symbol BinaryToDecimal__FPc was referenced
from module /ds2/home/dsadm2/Ascential/DataStage/Projects/LTRA_PROJ_ETL_02/RT_BP564.O/V0S0_BinaryToDecimal_Transformer_0.o(), but a runtime definition
of the symbol was not found..

Is it possible to post the C++ code you have created.
I guess you have selected the Object type as Library. Since you have created a object file select the object as the option.

Code: Select all

long     BinaryToDecimal(const char * pstrBinary)
{
     int     intLoop=0;
     long     lngReturn=0L;
     long     lngMultip=1L;
     for (intLoop=0; intLoop < (int)strlen(pstrBinary); intLoop++)
          {
          if ('1' == pstrBinary[intLoop])
               {
               lngReturn += lngMultip;
               }
          lngMultip *= 2;
          }
     return     lngReturn;
}

and yes I'm giving the full path of the object file which i'm creating.

And what about this....

I have done the following:
Type:External Function
Object Type: Object
External subroutine name: BinaryToDecimal
Return type:long
Library path:/home/manual2/intest/binarytodecimal.o

Compiling on AIX as below:
xlC_r -c binarytodecimal.c -o binarytodecimal.o

Error message while validating or runtime is:
Transformer_0: Failed to load the library "V0S0_BinaryToDecimal_Transformer_0.o"; either the directory containing the library file
is not on the library search path, or the library was compiled on a system
that is incompatible with this system: Could not load "V0S0_BinaryToDecimal_Transformer_0": rtld: 0712-001 Symbol BinaryToDecimal__FPc was referenced

Give permission 775 (or 777 for testing) to the object file created.

Hi,
I am an amateur Datastage guy and I haven't used IConv, OConv so far.... but I recollect from reading the documentation that "Radix Conversions" are possible using IConv, OConv.

Good luck,

However these functions are not exposed in C++ and so are not available in parallel routines or Build stages.
