Description Stepan Kasal 2006-10-13 15:39:25 UTC
With perl-5.8.8-10 on i686, I see a warning whenever I run aclocal:

Use of uninitialized value in concatenation (.) or string at
/usr/share/autoconf/Autom4te/XFile.pm line 229.

The message does not appear with perl-5.8.8-8 on x86_64.

Lines 216-229 are:
sub lock
  my ($fh, $mode) = @_;
  # [...]
  if (!flock ($fh, $mode)

The message comes from the call to "lock" in /usr/bin/autom4te.
(autom4te is executed by aclocal.)

Steps to reproduce:
wget http://ftp.gnu.org/pub/gnu/gawk/gawk-3.1.5.tar.bz2
tar xjf gawk-3.1.5.tar.bz2
cd gawk-3.1.5

a fix

The message is triggeted by this: $ENV{'MAKEFLAGS'}

The issue is fixed in autoconf-2.60, where is this patch taken from.

Comment 2 Stepan Kasal 2006-10-13 17:05:43 UTC
There is one factor which I missed previously: the message appears only when
working in a NFS mounted directory.
But then it is triggered by every call to autoconf, automake, autoheader, or

fixed in FC6, Rawhide and RHEL-5 with autoconf-2.59-12
