PRO*C compiling AIX 5.3

In November, I posted a workaround here to this issue which I had run into and which had been previously referenced on this list. At that time I couldn't tell precisely which AIX release introduced the problem, but this morning I received an email from Christoph Brändle which ties it down to 5300-06 and identifies that Oracle 10g Release 2 still exhibits this problem on AIX 5.3.  

KEN WALLIS You have posted a problem concerning the /usr/include/standards.h and its solution in the www.orafaq.com <http://www.orafaq.com/> mailing list last November.  

I just run into the same problem today with AIX 5300-06 and Oracle 10.2.0.2.0. Apparently, Oracle 10g Release 2 is still not able to handle the #warning.  

We also have an AIX 5300-05 machine, and here the problem does not occur. I was able to verify that the change in the standard.h file occurred with the patch from 5300-05 to 5300-06.  

You might want to add this comment to your valued posting.

PRO*C compiling AIX 5.3
2007-11-27 - By Ken Wallis

In July, Brian Shanblatt posted a query to this list regarding a problem with 9.2 Pro*C and AIX 5.3 for which there was no adequate answer (http://dba.5341.com/msg/81329.html).

However, his post turned up in a Google search when I ran into the same error with the same components and this helped me understand that I had a soluble problem which I have now overcome. I wanted to add some value by posting a follow up.

Brian, I recently ran into this same issue with a properly installed version of Oracle 'Pro*C/C++: Release 9.2.0.1.0' on AIX 5300-06. It appears that between AIX 5300-04 and 5300-06 IBM put a section into /usr/include/standards.h with this #warning line and Pro*C/C++ doesn't like it. This warning then appears to throw off the entire precompilation phase such that simple types such as size_t aren't defined and everything falls in a heap.

After unsuccessfully trying various fiddles involving DEFINE= in my proc invocation, I decided that rather than modify standards.h in /usr/include, I would make a local copy of standards.h in the directory with my source code and header files and edit that.

I changed IBM's:

#if defined(__IBM_PP_WARNING)
#warning The -qdfp option is required to process DFP code in headers.
#else
#error The -qdfp option is required to process DFP code in headers.
#endif

into:

#if !defined(__IBM_PP_WARNING)
#error The -qdfp option is required to process DFP code in headers.
#endif

My proc invocation already included INCLUDE=., so this local version of standards.h got pulled in instead of IBM's one and the proc command in the makefile then went through successfully.

Hi Peter and all.

Thank you for your reply.

I just did an install of the 9.2.0.8 patchset, which upgraded and relinked everything.

The same problem occurred with pro*c on the standards.h file.

I then relinked the precompilers and the shared client libraries.

Same error.

It might have something to do with the AIX patchsets. Metalink lists a whole bunch, and I will have the sysadmins on the machine check that we have them.
