[amontoison]

@jfowkes It's related to SSIDS.

[nimgould]

Please provide line numbers, we'll never find anything wthout them

[nimgould]

Which compiler? ssids is known not to work with ifx, so is this ifort?

[nimgould]

We have

error #5633: Internal compiler error: segmentation violation signal raised Please report this error along with the circumstances in which it occurred in a Software Problem Report. Note: File and line given may not be explicit cause of this error.
compilation aborted for fkeep.F90

when compiling with the latest
ifx (IFX) 2024.2.1 20240711
Copyright (C) 1985-2024

(and previous versions)

I thought we had made a policy decision not to use ssids in interface tests, the tests for ssids should be for the fortran?

[nimgould]

I have no idea what happens on a Mac

[jfowkes]

@nimgould I think he means the error happens on a Mac with an Intel processor (ifort/ifx are no longer supported on macs, Intel are bitter that they got dropped in favour of ARM).

[amontoison]

Sorry but it's the version cross-compiled by Yggdrasil so it's in release mode (-O3) and harder to debug.
I cross-compiled it with GCC 9.1.

[amontoison]

It also fails on Mac ARM so the issue is related to Mac.
The cross-compiler for Mac ARM is GCC 12.1. 🤔

[nimgould]

OK, but I'll be searching for a molecule in an ocean on a distant planet without a line number to examine

[amontoison]

Ok, I think that the issue is the library of C++.
With the cross-compiler, libgalahad_* is linked to libc++ and not libstdc++.

In Meson, I have these flags:

# Link flag for C++
lstdcpp = '-lstdc++'
if host_machine.system() != 'linux'
  if cxx.get_id() == 'clang' or cxx.get_id() == 'clang-cl'
    lstdcpp = '-lc++'
  endif
  if cxx.get_id() == 'intel' or cxx.get_id() == 'intel-llvm'
    lstdcpp = '-cxxlib'
  endif
  if cxx.get_id() == 'intel-cl' or cxx.get_id() == 'intel-llvm-cl'
    lstdcpp = '/Qcxxlib'
  endif
endif

but I compile everything with g++, even on Mac so I don't understand why it's linked to this library at the end.

[amontoison]

You can debug it on Mac mini with the help of Jari.
You just need to compile GALAHAD with clang and clang++.

[nimgould]

I tried to compile GALAHAD with flang here in linux land the other day, and it couldn't cope with ssids ... what fortran compiler were you using with clang?

[nimgould]

Actually, it was worse than that, flang hasn't implemented many of the features we need, e.g,
Compiling spm error: loc("/home/nimg/Dropbox/fortran/optrove/galahad/objects/pc64.lnx.fln/double/spmf.F90":97:4): flang/lib/Lower/CallInterface.cpp:949: not yet implemented: support for polymorphic types

[jfowkes]

@amontoison are you maybe using clang++ as the linker at the end? I don't think SSIDS will play nicely with clang++.

[amontoison]

I need to check the builds on Yggdrasil.
This is the PR: JuliaPackaging/Yggdrasil#10257

I don't see anything wong in the logs:

@imciner2
Ian, do you have an idea why I have an error with libc++ on Mac while I cross-compiled GALAHAD with the compilers gfortran / gcc / g++ (Yggdrasil) and linked with -lstdc++'?
I didn't wanted to compile with clang++ and clang because it was never tested with these compilers.
