icu @67.1_4: ppc64 build fails

[barracuda156]

Opening a dedicated ticket, since this appears to be one of the core problems with building for ppc64. I have added muniversal portgroup, depends_skip_archcheck-append python27, depends_skip_archcheck-append ld64 and depends_skip_archcheck-append llvm-3.4 - otherwise it asked for building llvm-3.4 universal, which is known to fail: ​https://trac.macports.org/ticket/64253

I also changed the linker to +ld64_97 as recommended here: ​https://github.com/classilla/tenfourfox/issues/498#issuecomment-418912902

Then icu build proceeded with gcc-mp-7, but eventually failed on this:

This error:

ld: absolute addressing (perhaps -mdynamic-no-pic) used in icu_67::FixedDecimal::getFractionalDigits(double, int) from plurrule.o not allowed in slidable image. Use '-read_only_relocs suppress' to enable text relocs

Is quite commonly found when building some code archs. The fix is usually to do what the error is telling you to do, ie add:

-read_only_relocs suppress

to the linker args.

You will find a number of cases in the ports tree where I did this, and perhaps others have done it too, I didn't look at them all. You usually need to restrict that linker flag to just the build archs where the error is generated, as it is not accepted by some other build archs.

If you grep the ports repo for read_only_relocs you will find some reasonable-looking examples.

As to WHY this is needed, the best explanation I have come across is here:

[kencu (Ken)]

By the way, it is quite possible that we might find some issues with ppc64 and ld64-127.

I believe that by the time ld64-127 was being worked on at Apple, ppc64 was dropped, and only the vestigial ppc7400 was left. So there might well have been no error checking and no debugging being done to any significant degree with respect to ppc64 in ld64-127.

cctools is likely worse -- the version we use in macports has not been tested against ppc64 in more than a decade. I had to do some work just to get i386 working again on the last upgrade, and even after that someone found a weird rounding error that had been missed by upstream as the code path was never used.

So -- buyer beware!

yes, me too.

-read_only_relocs suppress changed the error message slightly, but it still failed similarly.

At this moment in time, I have no idea why it fails. This looks wrong, but may not be the whole error:

I'll attach the full log for anyone inspired.

[kencu (Ken)]

I tried building with -no-pie in the CFLAGS and CXXFLAGS, but that did not fix it. Then I added -Wl,-read_only,relocs,suppress to the LDFLAGS, along with the -no-pie and that also did not work.

I wondered if perhaps something was up with ld64-97, which I am using at the moment to link, but using /usr/bin/ld to do the link also failed in a similar way.

So -- something about the way that function is written and is linking is making ppc64 darwin very cranky.

Just exactly what it is, I don't know at the moment.

[kencu (Ken)]

barracuda, can you try building ICU outside of macports with your handmade gcc7 (and if that fails, one of the newer ones)?

Do it like this:

cd ~
mkdir icutest
cd icutest
cp /opt/local/var/macports/distfiles/icu/icu4c-67_1-src.tgz ./
open /opt/local/var/macports/distfiles/icu/icu4c-67_1-src.tgz
cd icu/source
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

then use the path to your desired gcc7 in here:

CC="/opt/universal/bin/gcc-mp-7 -m64 -O2" CXX="/opt/universal/bin/g++-mp-7 -m64 -O2" PYTHON=/opt/universal/bin/python2.7  ./configure

and then do this:

make VERBOSE=1 -j4

and see what happens.

If any of your gcc versions inside or outside of macports can build icu 64 bit, let me know.

Yeah, so same error exactly...

Is there any gcc version you have that uses Iain's tools (cctools/ld64)? gcc11?

At the moment, I don't know if this is a ppc64 linker bug, or something to do with the way that function is written in ICU.

No, since from what I understood from Iain, at the moment it is pointless to use his xtools, there is unresolved library conflict issue. (Correct me if I am wrong.)

I am very much willing to try rebuilding gcc11 with linking to his xtools, once we have a procedure to accomplish that.

[kencu (Ken)]

different function, at least. So it’s not just that one function.

OK, this looks to me like gcc or ld64 issue, not ICU or MacPorts issue.

next step might be to see if Iain’s tools fix it with his patches to ld64.

Hmm, I tried now with gcc11 and it looks it might have built.
