[Bug-tar] tar-1.13.93

[Harald Koenig]

Hi,

I've buid  tar-1.13.93 on various plattforms  and found some minor problems 
which I'd  like to report:



1) ICONV_CONST

all plattforms:  src/utf8.c needs ICONV_CONST which does not get set by
the configure script.  

there seems to be code for a test in m4/iconv.m4, but just running 
autoconf didn't help, so I had to set this manually...



2) snprintf

src/xheader.c needs snprintf.  

SunOS-5.5.1 does not have snprintf at all.  
either you have to provide a workaround (and check in configure), 
or just use snprintf as it's totally save to print one long integer
into a 64 byte buffer (as it's used in xheader.c).

AXP OSF1-V4.0 does have snprintf only in /usr/lib/libdb.*, so you need "-ldb" 
for linking.


3) /dev/zero, tests and HP-UX

hpux (al least 10.20, 11.00, 11.22) doesn't have /dev/zero by default (11.11 
does).
this causes two tests to fail:

        listed01.sh
        multiv01.sh

while it's possible (as root) to create that device on HPUX 11.* with

        mknod /dev/zero c 3 4 
        chmod 666 /dev/zero

but this won't work for hpux 10.20.   for 10.20 it's only possible to use

        mknod /dev/zero c 3 3
        chmod 666 /dev/zero

(minor id 3 instead of 4!) which doesn't zero the read buffer and thus
gives back random trash (so better call it /dev/trash ;-)


a portable way to produce a stream of NULL bytes would be e.g.

        yes "" | tr '\012' '\000' | ....




4) strtoull

AXP OSF1-V5.0 does have strtoull, needed by lib/strtoumax.o.
from that config.h :

        /* Define to 1 if you have the declaration of `strtoull', and to 0 if 
you
           don't. */
        #define HAVE_DECL_STRTOULL 0

        /* Define if you have the 'long long' type. */
        #define HAVE_LONG_LONG 1

because lib/strtoimax.c only includes a prototype but no code:

        #ifdef UNSIGNED
        ...
        # if !HAVE_DECL_STRTOULL && HAVE_UNSIGNED_LONG_LONG
        unsigned long long strtoull (char const *, char **, int);
        # endif

I don't have  a workaround for that one yet.
I'm using gcc-3.3.2 on AXP OSF1-V5.0 (and all plattoforms).




here is a list of tested plattforms:

HP-UX-B.10.20
HP-UX-B.11.00
HP-UX-B.11.11
HP-UX-B.11.22
FreeBSD-4.7
RedHat-6.2
RedHat-7.1
RedHat-9.0
SuSE-6.2
IRIX64-6.5
AIX-4.3
AIX-5.1
SunOS-5.5.1
SunOS-5.8
OSF1-V4.0
OSF1-V5.0


thanks for gnu-tar !!
