[Bug c++/13682] New: Compile error with cstdio: fgetpos not declared on AIX

[richard_wheeler at cinfin dot com]

Attempting to compile C++ module from Berkeley-db 4.2.52 that gets the 
following error.  I do not understand why it is having a finding the standard 
library functions.  I am hoping someone here could point me the right way.

Thanks

Not a bug, looks like you GCC is not really compiled for you OS version.
In the preprocessed file, I see:
# 295 "/cmDevTest/Dev/local/bin/../lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h" 2

extern int fgetpos64(FILE *, fpos64_t *);
......
using :: fgetpos

Why did the compiler did not pick up the actual entries in stdio.h?  I attached 
the file referenced.  It shows the following at that position in the file:

extern int	fgetpos(FILE *__restrict__, fpos_t *__restrict__);
extern int 	fseek(FILE *, long int, int);
extern int	fsetpos(FILE *, const fpos_t *);
extern long	ftell(FILE *);

Because it looks like one of your header file somewhere either in installed by gcc or your system 
header files is changing the definition. Still not a GCC problem, try to make sure that all of system 
header files are uptodate.  And then reinstall GCC.

Are you saying that the line in the .ii file is not the actual header file 
being used by GCC?

The general reply to this was "your GCC was not compiled for your system". 
That isn't the case.  I have two compiles on two different systems.  One if
version 4.5.0 and the other version is 4.3.1 compiled on AIX 5.3 TL05 CSP.  The
4.5.0 version I just finished compiling and it still has the problem.

[Bug c++/13682] Compile error with cstdio: fgetpos not declared on AIX

[oliver at FreeBSD dot org]

------- Comment #8 from oliver at FreeBSD dot org  2009-08-20 07:31 -------
I fixed this on my AIX system by changing
/opt/pkg/gcc34/include/c++/3.4.6/cstdio.

I uncommented the undef's:

<snip>
// Get rid of those macros defined in <stdio.h> in lieu of real functions.
#undef clearerr
#undef fclose
#undef feof
#undef ferror
#undef fflush
#undef fgetc
/* get db4 to compile #undef fgetpos */
#undef fgets
/* get db4 to compile #undef fopen */
#undef fprintf
#undef fputc
#undef fputs
#undef fread
/* get db4 to compile #undef freopen */
#undef fscanf
#undef fseek
/* get db4 to compile #undef fsetpos */
#undef ftell
#undef fwrite
</snip>

This made db4 compile..... So I guess this is of course a gcc problem because
this headers are supplied by gcc!
As in #7 stated, on AIX the functions are redefined to use the 64-Bit functions
for large-file support. #undef'ing them later removes the definition to the
64-Bit functions but only them are declared on aix when large file support is
defined.

------- Comment #7 from patrick133t at yahoo dot com  2008-06-03 18:19 -------
I see this on AIX 5.3 also. I tracked it down by creating a simple program that
just does a #include <string> and then saw that it worked when compiled as:

g++ -c -o bar.o bar.cc

However, it fails to compile when I do

g++ -c -D_LARGE_FILES -o bar.o bar.cc

I then grepped all the files that get included in the preprocessed output and
found only these two reference _LARGE_FILES:

/opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3.2/include/stdio.h
/opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3.2/include/sys/types.h

The problem appears to be that stdio.h makes the following definitions that
then get #undef'ed in cstdio:

#define fseeko fseeko64
#define ftello ftello64
#define fgetpos fgetpos64
#define fsetpos fsetpos64
#define fopen fopen64
#define freopen freopen64

Because of these defitions, the prototypes in the preprocessed output have a 64
on the end but the using ::fsetpos do not have them, and we get the error.

I really think this is GCC's problem and not caused by AIX headers.
