OCaml/ppc64

[David Woodhouse]

Bored again, playing with OCaml/ppc64 for a bit of light relief.

boot/ocamlrun ./ocamlopt -nostdlib unix.cmxa -g -I stdlib -I ../otherlibs/unix ocamlbuild/ocamlbuild_executor.cmx ocamlbuild/ocamlbuild_pack.cmx ocamlbuild/ocamlbuild_unix_plugin.cmx ocamlbuild/ocamlbuild.cmx -o ocamlbuild/ocamlbuild.native
/usr/bin/ld: ocamlbuild/ocamlbuild_pack.o(.text+0x500c): unresolvable R_PPC64_REL24 relocation against symbol `ceil@@GLIBC_2.3'
/usr/bin/ld: final link failed: Nonrepresentable section on output

How do I make it link against -lm? Why doesn't this bite elsewhere?

At least on i386 it is linked against -lm. It isn't visible from
the build command.

David got it building in the end, and I've rebuilt all of the OCaml
packages in Rawhide (again ... and on the same day that OCaml 3.10.2
was released as well ...)

They all build without error on ppc64 but that doesn't necessarily
mean they will run.  Just building them exercises the bytecode
interpreter (written in C) and if we're lucky ocamlc.opt and
ocamlopt.opt and on a rare few packages some tests.  If someone can
lay their hands on a ppc64 machine they can try them out.

On the other hand it was a good enough excuse to finally get rid of
'ExcludeArch: ppc64' everywhere.

Rich.

Mail me a SSH public key, and/or tell me what to test.

All I've done this time is dust off the old patch I had for 3.09.3 and
make it build again. I haven't done any real work. So I still expect to
see that SEGV in freetennis which stopped me from shipping the patch
before. Although every other test case I could come up with was working
fine.
