Error while compiling parallel routine

[bala_135]

Hello All,

I have written a c code which takes 2 arguments and adds it and return it to the main program.I have compiled and sucessfully got the result.Type i have taken care.

I want to call this external function in my stage.I am using a parallel routine.

In the routine,I am giving the libary path where my object code and exes are located.

When i use this in the job i am getting the following compile error.

Do i need to do some setting to make it work.

Thanks,

Bala,
I am assuming that you have installed .NET 2003 C++ compiler and your parallel jobs using Transformer stage are working.

If above assumption is correct, then just make sure the path that you populated in the Library Path of the general page is pointing to the path of the Object you created, e.g. C:\yourC++Loaction\TrxFuncs.o.

Hi Istsaur,

Thank you very much for the reply.
I am using a Turbo C complier to create the c program(complied,sucesssfully ran there),it creates the object code as .obj and an executable file *.exe.

Now in my library path when i give the object file its showing an error.

.NET 2003 C++ compiler is installed because my other thransformer jobs are working fine.

I am having a doubt is this the problem.Creating a c program in turbo c complier and trying to call that in .NET 2003 C++ compiler.

Regards,
Bala.

Check out this error. You may need to set a user defined environmental varriable called PDW and assign the default project directy in it or a '.'.

Hi Kumar/Istsaur

I have set the PWD variable pointing to my project now that warning is gone but still i cannot compile it.

Regarding the setting of the library path.I have folder which has the
C code,object code and executables.I am browsing and giving that in the library path is that right because each time its saying cannot open the file.

Error message.
Output from transformer compilation follows:

Hi Bala,
It's a problem that you creating a c program in turbo c complier and trying to call that in .NET 2003 C++ compiler. Your object code should definetely have a .o not a .obj.

I could see that you tried to run the TrxFunc.o example program provided from DataStage EE. I have tried TrxFunc.o routine on my 7.5x2 EE and it works as expected. You are almost there. Good luck.

Also check the necessary permision, including executable permission available for that object file.
