Hi,
has anyone managed to install OCaml+OPAM on a IBM BlueGenemachine?
- When I try to compile the OCaml compiler with gcc, I get a Makefile
error related to a missing none.o file.
- To install OPAM, I do the following:
|wget https://raw.github.com/ocaml/opam/master/shell/opam_installer.sh -O - | sh -s /usr/local/bin/
but OPAM tells me it does not have a binary distribution for my architecture (ppc64)
- I tried to compile the code into bytecode on an Intel machine and copy it to the BlueGene, but the ocamlrun ppc won't
execute the bytecode generated for Intel. Is there an endianness incompatibility in the bytecodes?
I don't know what else I can do to make my code run on a BlueGene machine (Mira at Argonne), and I am trying to convince people
that HPC is not only limited to Fortran or C/C++ using MPI and OpenMP :-(
Help !!!
Anthony

Using the current development version of OCaml, everything compiles perfectly under ppc64. I could also install opam with no problem.

I've already compiled opam using ocaml 4.01 or 4.02 on ppc64el without any issues. So, I am a bit surprised. Maybe I've missed something though.

In my experience, all four architectures didn't cause issues wrt. ocaml projects (or ocaml itself). So, I'm genuinely interested in hearing what could go (or went) wrong there and how observed issues were fixed. ocamlopt is certainly not available everywhere and sometimes, one has to put a little patch relevant on bytecode architectures. but i didn't see more complex or deep issues there. -- Mehdi ^ permalink raw reply [flat|nested] 6+ messages in thread

If this is correct, "opam switch" should be fixed but I suspect many OPAM packages don't work on bytecode architectures (is there any QA done on such architectures?). In Debian, we often have to fix packages... Cheers, -- Stéphane ^ permalink raw reply [flat|nested] 6+ messages in thread
