[Klone-users] error checking va_list caused by shift command

[Mickael Auger]

Hi KLone team,

I tested KLone 2.2.0 on two Linux :
   1- Mandrake Linux 9.2
   2- Ubuntu 7.10

For my first Linux I have an old "shift" command and I have any problem to
make KLone :)

But for my second Linux I have a new "shift" command and I have the next
problem at the first make :(

I search the cause of this problem and it comes "makl_checkfunc" function of
"makl_code.sh" called by "configure" :
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
makl_checkfunc          0   "syslog"
makl_checkfunc          0   "mkstemp"
makl_checkfunc          0   "localtime_r"
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Indeed this "makl_checkfunc" function call "shift" command 4 times, but the
third and the fourth are optionnals :
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
makl_checkfunc ()
{
    opt="$1"
    id="$2"
    nargs=$3
    flags="$4"
    shift; shift; shift ; shift
    ...
}
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
However the new version of "shift" command stops the process if there are
not enough parameter.

I know that this new behaviour is very strange and doesn't match with
documentation of "shift" but I think that other KLone users would have this
problem.

For information, I solve temporaly this porblem to replace the
"makl_checkfunc" calls in "configure" by :

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
makl_checkfunc          0   "syslog" "" ""
makl_checkfunc          0   "mkstemp" "" ""
makl_checkfunc          0   "localtime_r" "" ""
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

A lot of functions use the "shift" command without have enough parameter but
they don't called during my make process.

Bye.
