Please would you let us know what you were trying to do rather than just sending us a dump of output

@jajhall Thank you for responding. I was building HiGHS; as you can see, atomics does not link, because 32-bit hardware does not support 8-byte atomics. GCC can emulate those, however it should be linked against libatomic.

Ideally configure stage should implement a test for hardware support for 8-byte atomics, if it fails without libatomic, then it should be added, and -latomic flag passed to the linker during the build.

As an example, see: https://github.com/facebook/rocksdb/blob/5fc57eec2b44337289f25c1b5687beb54ad709a2/CMakeLists.txt#L296-L312

I'll see what we can do, but support for 32-bit architectures is very low priority

Thank you. I am not asking to dedicate time to specifically support 32-bit platforms, but libatomic linking is trivial to add, and that will be a definite improvement.

P. S. I can actually take care of that, let me first ensure everything builds and tests pass.

@jajhall Sorry, been a bit busy. I have built HiGHS for ppc32, no extra patching (just libatomic linkage to unbreak the build), and 100% of tests pass.
I reckon, no reason not to support 32-bit platforms, as of now. It works.

@galabovaa Can the CMake patch in the link be incorporated?

galabovaa · 2023-05-18T20:19:12Z

Yes, the patch just needs to be modified to not require C++ 17 and we can add it to CMake. I will do that

barracuda156 · 2023-07-06T23:25:29Z

@galabovaa Has this been done, as of 1.5.3?

df73034 adds a conditional libatomic dependency to the meson.build.

barracuda156 · 2023-10-15T08:05:35Z

@HaoZeke Thank you, I will test it.

HaoZeke · 2023-10-15T12:05:04Z

@HaoZeke Thank you, I will test it.

Actually for 32-bit systems and the meson build, it is better to use #1460 and build with -Dhighsint64=False (otherwise it will segfault at runtime). This combination (the PR+build option) is tested on SciPy's CI (Linux 32-bit). Please report back if it doesn't work.

barracuda156 · 2023-10-15T12:34:14Z

@HaoZeke We built it with CMake: https://ports.macports.org/port/HiGHS/details

Do we need some special config options in that case? (I would rather not switch to meson, it is not mature enough build system IMO.)

P. S. Sorry, did not check it right-away when replied above.

That's alright, I from a quick look, it seems like HIGHSINT64 is off by default in CMake so it should be fine without any special considerations (this might change in the future so it might be best to explicitly set it in the cmake invocation).

jajhall · 2023-10-15T14:01:54Z

'HIGHSINT64' will always be off by default

jajhall · 2023-10-31T13:21:00Z

Is this fixed?

Fixes ERGO-Codegh-1294
