I've found a bug in autoconf related to the ls command's environment
variable QUOTING_STYLE.
By having QUOTING_STYLE=c in my environment, the following stanza fails.
### BEGIN ./configure stanza
# Do 'set' in a subshell so we don't clobber the current shell's
# arguments. Must try -L first in case configure is actually a
# symlink; some systems play weird games with the mod time of symlinks
# (eg FreeBSD returns the mod time of the symlink's containing
# directory).
if (
am_has_slept=no
for am_try in 1 2; do
echo "timestamp, slept: $am_has_slept" > conftest.file
set X `ls -Lt "$srcdir/configure" conftest.file 2> /dev/null`
if test "$*" = "X"; then
# -L didn't work.
set X `ls -t "$srcdir/configure" conftest.file`
fi
if test "$*" != "X $srcdir/configure conftest.file" \
&& test "$*" != "X conftest.file $srcdir/configure"; then
# If neither matched, then we have a broken ls. This can happen
# if, for instance, CONFIG_SHELL is bash and it inherits a
# broken ls alias from the environment. This has actually
# happened. Such a system could not be considered "sane".
as_fn_error $? "ls -t appears to fail. Make sure there is not a
broken
alias in your environment" "$LINENO" 5
fi
if test "$2" = conftest.file || test $am_try -eq 2; then
break
fi
# Just in case.
sleep 1
am_has_slept=yes
done
test "$2" = conftest.file
)
then
# Ok.
:
else
as_fn_error $? "newly created file is older than distributed files!
Check your system clock" "$LINENO" 5
fi
{ $as_echo "$as_me:${as_lineno-$LINENO}: result: yes" >&5
$as_echo "yes" >&6; }
# If we didn't sleep, we still need to ensure time stamps of
config.status and
# generated files are strictly newer.
am_sleep_pid=
if grep 'slept: no' conftest.file >/dev/null 2>&1; then
( sleep 1 ) &
am_sleep_pid=$!
fi
rm -f conftest.file
### END ./configure stanza
The reason for the failure is in the code
if test "$*" != "X $srcdir/configure conftest.file" \
&& test "$*" != "X conftest.file $srcdir/configure"; then
My ls is not aliased, but because of my use of the envar QUOTING_STYLE,
it makes $* look like this:
X "./configure" "conftest.file"
or
X "conftest.file" "./configure"
both of which fail the test.
Setting QUOTING_STYLE to an empty string causes ls to wig out in stderr
on each invocation, but it passes all of the tests for the two AUR
packages I was using it on, librelp and pcaudiolib. Within the above
stanza, QUOTING_STYLE needs to be accounted for to prevent this stanza
from failing incorrectly.
Relevant software versions follow:
ls (GNU coreutils) 8.30
autoconf (GNU Autoconf) 2.69
automake (GNU automake) 1.16.1
autogen (GNU AutoGen) 5.18.12
libtool (GNU libtool) 2.4.6.42-b88ce
Pacman v5.1.1 - libalpm v11.0.1
aurman :: 2.18-1
