Compiling samba 2.2.8 on HP-UX 11.00 - conflicting

[Ladner, Eric (Eric.Ladner)]

Comment the definition of vsnprintf out altogether.  If there is a
header for it in stdio.h, then it's a libc function (or something) and
shouldn't be redefinied in the source.  Wrap the whole function top to
bottom in a comment or find the HAS_VSNPRINTF definition in the main
definition header file and set it to 0 (I can't remember if that
funciton is wrapped in a define, but it should be).  I'm curious why if
some combination of HP-UX/gcc has the funciton, it's not beinig
identified at ./configure time and not compiled.

Thanks Eric, that fixed one of the functions. The functions are declared
as:

in stdio.h:
     extern int snprintf(char *, __size_t, char *,...);
     extern int vsnprintf(char *, __size_t, const char *, __va__list);

in snprintf.c:
 int vsnprintf (char *str, size_t count, const char *fmt, va_list args)
{  int snprintf(char *str,size_t count,const char *fmt,...)

I removed the const from the snprintf function in snprintf.c and that
fixed that conflict, but I'm not sure what to do about the vsnprintf
function. I can't see any differences! Then again, I'm not the worlds
greatest C programmer, so I'm probably missing something blindingly
obvious. Does anyone know what I can change in the vsnprintf function to
make the compiler happy?

Thanks

Adam Fox.

I believe the only difference is a 'const' modifier on one of the
arguments in the declaration of the function.  I can't remember if I had
to comment out the implementation part of the fucntions or not.

I edited the source and added the const to the file that didn't have it
and all was right with the world.

of snprintf


Hi all,

I'm trying to compile samba 2.2.8 on a HP-UX 11.00 system. I've run the
configure script without any arguments, but when I run 'make' I get the
following error:

Compiling lib/snprintf.c
lib/snprintf.c:777: conflicting types for `vsnprintf'
/var/bin/../lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.0/include/stdio.h:494:
previous
declaration of `vsnprintf'
lib/snprintf.c:792: conflicting types for `snprintf'
/var/bin/../lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.0/include/stdio.h:493:
previous
declaration of `snprintf'
*** Error exit code 1

I did some searching on the mailing list and found other people having
the same problem with other versions of samba, but I didn't find any
solutions. When I ran configure the following was reported about the
printf functions:

checking for asprintf declaration... no
checking for vasprintf declaration... no
checking for vsnprintf declaration... yes
checking for snprintf declaration... yes
[...]
checking for vsnprintf... yes
checking for snprintf... yes
checking for asprintf... no
checking for vasprintf... no

One suggestion I saw was to comment out line 492 and 493 of the stdio.h
from the HP-UX include directory, but I'm not too keen on mucking around
with the HP files. Is it possible to not redefine the snprintf functions
and just use the one that comes with HP-UX?

Any help is appreciated.
