DataStage® Release: 9x
Job Type: Parallel
OS: Unix
Additional info: AIX 7.1, IBM XL C/C++ for AIX, V10.1
Hi Experts,

Recently we have upgraded the OS from AIX 6.1 to AIX 7.1. We are using IBM Information Server v 9.1.2. While compiling PX jobs, it started giving below errors. We are certain that this is due to a compiler problem. However, wondering how to resolve the issue.

Diagnostic details:
> /usr/Xvacpp/bin/xlC_r -qversion
IBM XL C/C++ for AIX, V10.1
Version: 10.01.0000.0000

> uname -a
AIX hostname 1 7 00CFEBA74C00

> lslpp -l | grep "vac.C"; lslpp -l | grep "vacpp.cmp.core"; lslpp -l | grep "xlC.aix*"
xlC.aix61.rte 13.1.3.1 COMMITTED IBM XL C++ Runtime for AIX 6.1

Well... while I can't help with the specifics, it's known that DataStage is very particular about the compilers that will work with it. In your shoes I would be in contact with support, if you haven't already, but in the meantime I would check to see what exact compilers are supported by your DS version on AIX. You may need to upgrade DS or perhaps install the older version of the compiler? Heck if I know but we've seen many posts of issues similar to yours when someone attempts to use an "unsupported" compiler vendor or version. Sad

Thanks for the reply Craig.

I was told that the support for DS 9.1.2 on AIX was already reached the contract end time. Only help available is from the local unix SAs. BTW, I did try to compile a sample c++ program through the command line. That is also giving the same error. Unfortunately, still unable to find any solution from anywhere in the web.

Okay. But you should still be able to find out for your DS version and old O/S what compiler(s) are officially supported if the current one isn't to see if there's some way to get back to a working state. Another option could be to roll back to the previous O/S release for this server since it breaks DataStage (since I assume that's an important consideration) at least until you can upgrade DataStage to something that's actually supported and also supports that current O/S release. Food for thought.

"/usr/include/string.h". this concerns me. string.h is part of the C language and should not need a path to include it; has someone tried to override the standard one?

try this sample program. Can you compile this?

#include <cstring>
#include <iostream>
using namespace std;
int main()
{
char test[] = "test string and stuff";
char test2[100] = {0};
strcpy(test2, test);
cout << test <<" " << test2 << endl;
return 0;
}


-----
If that won't compile, can you get the release date on your compiler for me?
I don't know much about AIX. But assuming its generally unixish that should have worked.
