The patch alters the 'configure' script so that it's pickier about
rejecting warnings from the compiler.
The 'configure' script should be testing for -fPIC and -shared. It
should have something like this.
$as_echo_n "checking whether this system supports stdbuf... " >&6; }
CFLAGS="-fPIC $CFLAGS"
LDFLAGS="-shared $LDFLAGS"
stdbuf_supported=no
# Note we only LINK here rather than RUN to support cross compilation
cat confdefs.h - <<_ACEOF >conftest.$ac_ext
...
_ACEOF
if ac_fn_c_try_link "$LINENO"; then :
stdbuf_supported=yes
fi
So there should be an -fPIC and a -shared in the command line, but there
isn't in the diagnostics you mentioned. This is puzzling because the
diagnostic output you mentioned in <https://debbugs.gnu.org/35650#20>
did have -fPIC and -shared. So my guess is that somehow your 'configure'
script wasn't regenerated properly after you upgraded to my recent patch.
Please investigate why that is. I suggest looking into your updated
'configure' script to see whether it matches mine in this area. You can
also try putting the shell command 'set -x' into the 'configure' where
you want more debugging output.
Or, it might be easier for you to regenerate the source code from
scratch, by running this on a GNU/Linux platform:
git clone https://git.savannah.gnu.org/git/coreutils.git
cd coreutils
./bootstrap
./configure
make dist
and then unpacking and building the resulting tarball on HP-UX.
