Pro*C/C++ Precompiler Error when using OTT and CODE=CPP

Question

I am trying to precompile a Pro*C application for the company I am working.
Generating Include file and Intype file with OTT succeeded.
But invoking the Pro*C precompiler results in error messages concerning
the processing of the "size_t" structure being involved by including
the file "oci.h" in the OTT-generated Include file. This file in turn
seems to include "ociextp.h", "ociapr.h", "nzt.h" which cause the
precompiler to complain: (i translated some terms to english)
proc code=cpp cpp_suffix=cc intype=diacron.typ
'sys_include=(/u01/app/oracle/product/8.1.7/precomp/syshdr,
/usr/lib/gcc-lib/i486-suse-linux/2.95.2/include,
/usr/include/g++,/usr/include,/usr/include/linux)'

And the beginning code in the file transact.pc looks like:

#include <sqlca.h>

char username="***********";
MYTYPE *MyPtr;
EXEC SQL END DECLARE SECTION;

=============================================================
By the way, i figured out so many different settings and
alternative code placements now, I satisfy all guidelines of
the Pro*C-Programmers Guide, but I don't get that stuff running!
I'd appreciate any help!

Answer 1

When I first ran into this problem I scoured this forum and found the usual suspects (add the proper path to the pcscfg file by doing a "find /usr -name stddef.h -print"). Assuming that you did this and changed the reference from Suse to your distribution you can move to the next point.
I did this and still ran into problems. It turns out that with my distribution and version (Mandrake 8.1), I needed to reference the egcs version of these includes which were not installed by default. I needed into install the egcs packages. After this I had two references to stddef.h in my usr/include path. One was quite obviously the egcs version. I needed to use that one. It cleared up the problem.
[jflynn@CN83845-A /]$ find /usr/lib -name stddef.h -print
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/2.96/include/stddef.h
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/egcs-2.91.66/include/stddef.h
so I modified the pcscfg file as:
sys_include=(/usr/include,/usr/lib/gcc-lib/i586-mandrake-linux-gnu/egcs-2.91.66/include)
