Description
I have made a patch to make singular build on ARM ; that patch made its way upstream in singular-3-1-3, which isn't in sage yet.
So I'm attaching my patch here, in hope sage will either use my patch or use a newer upstream.
PS: the upstream report is: http://www.singular.uni-kl.de:8002/trac/ticket/299

sage 4.7.1 has shipped with a singular which doesn't build on ARM. When will a new (hence fixed) singular make its way into sage?

Hopefully during the Sage/Singular? Days (SD34) at the end of September, cf. #10903.
Otherwise you could make a new Singular spkg with your patch, based on Sage's latest one, which is singular-3-1-1-4.p13 from #11550 (merged into Sage 4.7.2.alpha0).

Julien, can you confirm that this ticket can be closed when #10903 gets merged?

If nothing was broken since my work with upstream, then indeed that ticket can be closed.
If a new problem arises, then that will be a separate issue.
I have to say that the discussion in bug #10903 where HAVE_ELF_SYSTEM shows up makes me nervous... that looks so wrong when you see the patch "Patch to directly detect ELF support" I gave upstream!

It's not that easy: the platforms in question do not define __ELF__
. In fact, they aren't fully ELF compatible, (it's about Macs), but Singular just needs an ELF-compatible dlopen here.

Then perhaps I should consider providing a patch basically doing s/HAVE_ELF_SYSTEM/HAVE_DLOPEN/g...

Can anyone test this on ARM now that #10903 has been merged?
comment:9 Changed 8 years ago by
I meant: test the new singular spkg from #10903 (merged in sage-4.7.2.alpha4) on ARM?
comment:10 follow-up: ↓ 11 Changed 8 years ago by
Is the spkg attached to the bug report the one to use, or am I supposed to also add the patches?

It seems the problem was building the spkg on ARM. So it should be sufficient to build the spkg from #10903 on ARM.
Of course, if you want to test that it actually works, you also need the patches. But instead you can also download and build sage-4.7.2.alpha4, which includes the new Singular spkg.

I downloaded : http://boxen.math.washington.edu/home/release/sage-4.7.2.alpha4/sage-4.7.2.alpha4/spkg/standard/singular-3-1-3-3.p1.spkg

From those the first one worries me most : why is it trying to find main in a lib!? I think that last linking line lacks something like "-shared" !
