bug#35650: [PATCH] Improving HP-UX support

[Osipov, Michael]

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
