Hi folks,

please find a patch attached to properly compile and link GNU coreutils 
8.31 on HP-UX IA64. As of now, it does not compile out of the box.

The patch includes these changes:

* basenc.c: HP aCC does not allow anonymous unions inside structs, I 
have named it otherwise the compilation fails
* blake2/blake2.h: __attribute__((packed)) does not exist in HP aCC, use 
#pragma pack
* copy.c, mkfifo.c: disable SELinux code if it is not available
* system.h: use __attribute(x) on a GNU-style compiler only
* configure.ac, local.mk: use HP aCC-style linker options for libstdbuf

Compile instructions:
> export PREFIX=/opt/ports/coreutils
> export LIBDIR=$PREFIX/lib/hpux32
> export CONFIGURE="./configure --prefix=$PREFIX --libdir=$LIBDIR"
> export CPPFLAGS="-I$PREFIX/include -D_INCLUDE_STDC__SOURCE_199901"
> export LDFLAGS="-L$LIBDIR"
> autoreconf -fi
> FORCE_UNSAFE_CONFIGURE=1 gl_cv_have_include_next=no ac_cv_func_getacl=no ac_cv_func_aclsort=no ac_cv_header_sys_bitypes_h=no $CONFIGURE
> gmake install

The patch isn't perfect, some issues need to be discussion because I 
don't know yet how to solve them:
* copy.c, mkfifo.c: for some reason the code compiles w/o changes 
although SELinux is not available
* I have disabled the compilation of b2sum completely because gmake 
repeatedly quits with:
> gmake[2]: *** No rule to make target '/var/tmp/AAA000546.i', needed by 'src/b2sum-md5sum.o'.  Stop.
> gmake[2]: Leaving directory '/tmp/system-compile/gnu/coreutils-8.31'
> gmake[1]: *** [Makefile:12647: all-recursive] Error 1
> gmake[1]: Leaving directory '/tmp/system-compile/gnu/coreutils-8.31'
> gmake: *** [Makefile:6827: all] Error 2
* The configuration of PIC and shared library is for HP-UX now. At best 
autotools would determine that with some default m4 file.

Note: I am not subscribed to this list.

Regards,

Michael

These selinux interfaces are provided by gnulib,
and so should automatically by ignored on HPUX.
I.E. I'm not sure this part is needed at all.

That's a bit awkward,
also this file comes from blake2 upstream source on github,
so you might want to broach the change there.

The only use of __attribute is:

src/libstdbuf.c:/* Use __attribute to avoid elision of __attribute__ on SUNPRO_C etc.  */
src/libstdbuf.c:static void __attribute ((constructor))

So we should probably have special __hpux handling in that file
rather than doing the above.

This is all dependent on stdbuf actually working on your platform.
Possibly the most appropriate change would be to use __attribute
rather than __attribute__ in configure.ac

This would need to be conditional,
again if stdbuf does actually work on hpux.

Thanks for the bug report. I installed the attached patches to coreutils=20
on savannah to fix some (but not all) of the bugs, and some other=20
C99-related bugs I noticed, and have some further comments and questions.

Fixed in the 3rd attached patch, in a slightly-different way.

As near as I can make out, that code (a) doesn't need the packed=20
attribute on any popular platform, and (b) wouldn't be portable among=20
Standard C platforms even if Standard C had the packed attribute. I'll=20

As you noted, this patch isn't needed (the code builds without it) so=20
let's omit the patch.

I don't see why these patches are needed. 'configure' should arrange for=20
libstdbuf to be built only if you are using GCC. If libstdbuf is being=20
built when you use HP-UX aCC, that suggests there is a bug in=20
'configure.ac' and we should fix that bug rather than try to port=20
libstdbuf to HP-UX.

Why do you need all those flags and why do you need to use gmake? Plain=20
'./configure; make' should work. The fact that you need those flags=20
suggests that there is a bug in configure.ac, and it'd be better to fix=20
the underlying bug than to try to paper around it (and possibly=20
introduce further bugs).

Presumably your top-level Makefile is messed up somehow. Please=20
investigate the rule for building b2sum that is in 'Makefile', and try=20
to figure out how it got corrupted. It might be a bug in the way=20
'configure' calls 'sed', or a bug in your 'sed' or 'awk' implementation.

Plain './configure; make' should work and if it doesn't work we should=20
fix it. Normally it does not build shared libraries or try to use PIC;=20
although you can arrange for it to do so that is lower priority for us.

I'll cc: this email to contact@HIDDEN to let them know about the=20
problem (if you're just catching up you can see the thread at=20
<https://bugs.gnu.org/35650>).

We shouldn't simply push this problem upstream to the BLAKE2=20
maintainers, as the BLAKE2 code is now in coreutils and if it breaks a=20
build then it's our responsibility to fix it. So for now I installed the=20
attached patch into coreutils, which I hope works around the BLAKE2=20
code's problem.

The underlying problem is that the reference code's definition of the=20
BLAKE2_PACKED macro assumes that the compiler is compatible with either=20
GCC or with Microsoft's C compiler, and HP-UX aCC is neither. As far as=20
I can see, for blake2.h on typical current platforms, there is no need=20
to use __attribute__ ((oacked)) or the Microsoft equivalent because the=20
data structure is already packed well enough, so the attached patch=20
simply skips the attribute unless we know that it will work.

I also noticed that the BLAKE2 code is not portable code according to=20
either POSIX or to the C standard, since it assumes types like uint64_t=20
that both standards say are optional. If that's OK with the BLAKE2=20
maintainers then the attached patch should suffice, as it should be=20
"good enough" for most common platforms. If you want the code to be=20
portable, you'll need to arrange for it to pack and unpack by hand, at=20
least on platforms that don't support a packed attribute and/or don't=20
support types like uint64_t.

How try that out? I have it in place and we'll know it in an instant:

aCC does not exit with non-zero, it just prints a warning. configure.ac 
makes false assumptions here at the end. Personally, I don't need 
stdbuf. If it really should only be compiled with GCC, you should test 
for GCC only.

Drop the hunk for system.h if you think it is not necessary.

I agree here, I will take on this in the next round of patches if you 
don't mind. I wanted to avoid a huge patch in the first place.

Right now, it is a bit awkward. After a 'gmake clean' and 'configure' 
it works again. I will leave it as-is for now and maybe have a look at 
it later.

See above.

OK, I installed the attached patch to try to fix this problem with
'configure'. Please give it a try. We may need some more patches to fix
the problems you evidently observed with #include_next, getacl, aclsort,
and sys/bitypes.h.

I do not really understand the purpose of the patch as it does not 
really test for PIC/shared. This [1] is a viable approach I have taken 
to make it work for linker style on HP-UX. I guess one could steal that 
and reuse for -fPIC/+z.

WDYT?

According the manual [1] the compiler supports #include_next, but for 
some strange reason it does not when -include is used. The funny thing 
is -include isn't even in the manual.

This one comes from:
 > @USE_XLC_INCLUDE_FALSE@src_b2sum_CPPFLAGS = -include config.h

I will inquire this with HPE because it looks fishy to me.
I don't know how to solve this differently for now, but to disable 
include_next in configure.ac if the compiler is aCC.

I checked acl.m4, headers in /usr/include/, manpages with errno as well 
as the affected C files:

* configure properly detects everything
* the code compiles flawlessly

so both ac_cv_func_getacl=no ac_cv_func_aclsort=no can be dropped.

Note: I don't have ACLs explcitly in use on our servers.

the ac_cv_header_sys_bitypes_h=no is redundant because there is no such 
header file. It would default to no anyway.

So we're down to #include_next and the linking/PIC issue.

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.

=C2=A0 $as_echo_n "checking whether this system supports stdbuf... " >&6;=
 }
=C2=A0 CFLAGS=3D"-fPIC $CFLAGS"
=C2=A0 LDFLAGS=3D"-shared $LDFLAGS"
=C2=A0 stdbuf_supported=3Dno
=C2=A0 # Note we only LINK here rather than RUN to support cross compilat=
ion
=C2=A0 cat confdefs.h - <<_ACEOF >conftest.$ac_ext
=C2=A0 ...
=C2=A0 _ACEOF
=C2=A0 if ac_fn_c_try_link "$LINENO"; then :
=C2=A0=C2=A0=C2=A0 stdbuf_supported=3Dyes
=C2=A0 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.

Better yet, let's stop using the -include option as it's not portable.
The -include option was used only to attempt to keep b2sum.c identical
with upstream, but we've already given up on that for other reasons, so
I installed the attached patches to fix this (the first patch drops
-include, the second patch lessens changes from upstream).

Its support for the -include option is flaky.  Problem reported by
Michael Osipov (Bug#35650).  Plus, we could run into other
compilers that don=E2=80=99t support any option like -include.  Change th=
e
code so that -include is not needed.  Although this causes us to
depart from the upstream version, we=E2=80=99re already doing that for
other reasons.
* configure.ac (USE_XLC_INCLUDE): Remove, as there=E2=80=99s no
guarantee a compiler will support something like -include.
* src/blake2/b2sum.c [HAVE_CONFIG_H]: Include <config.h>.
* src/local.mk (src_b2sum_CPPFLAGS): Add -DHAVE_CONFIG_H.
Do not use -include or a substitute.
