PCC-S-02015, unable to open include file(gnu/stubs-32.h)

Question

Hi,
I was trying to precompile one of the sample files from the "Pro*C/C++ Precompiler
Programmer’s Guide" and I got this error message:
Fehler in Zeile 7, Spalte 11, in Datei /usr/include/gnu/stubs.h
# include <gnu/stubs-32.h>
..........1
PCC-S-02015, Einfügedatei konnte nicht geöffnet werden.
(Which means "unable to open include file")
I couldn't find any an answer on the forum, so I figured it out for myself.
I just wanted to post it so in case somebody else faces the same problem, they would have the solution here.
The machine is a virtual Linux host running on a 64Bit architecture, so I was surprised why is it looking for stubs-32.h and not stubs-64.h.
The answer is in the stubs.h file:
#include <bits/wordsize.h>
#if __WORDSIZE == 32
# include <gnu/stubs-32.h>
#elif __WORDSIZE == 64
# include <gnu/stubs-64.h>
#else
# error "unexpected value for __WORDSIZE macro"
#endifSo let's check the bits/wordsize.h file:
#if defined __x86_64__
# define __WORDSIZE     64
# define __WORDSIZE_COMPAT32    1
#else
# define __WORDSIZE     32
#endifSo I figured out you can define __x86_64__ in two places:
The file: precomp/admin/pcscfg.cfg
Most probably you just need to add define=__x86_64__ and that should do the trick.
Unfortunately I couldn't try it because I didn't have write permission on that file.
The other way is to pass it in the command line:
proc sample1.pc MODE=ORACLE DEFINE=__x86_64__+
This way the precompiler created the output .c file without errors.
Cheers
PS: Don't try to define the __x86_64__ in the .pc file, or you'll get a warning when you compile the .c file. Not a big deal, just desn't look good :-D

Answer 1

Ideally speaking your pcscfg.cfg should have the paths to the directories where you will be getting all your headers from
Based on what linux flavor & version of gcc you have the following directory will have the headers you are missing
/usr/lib/gcc/ABC-XYZ-linux/<gcc_version_no>/include
where ABC could be i386/i586 depending on the hardware and XYZ could be the linux flavor like redhat/suse/whatever you have
