Possible problem with context using the ARM 64bit download for Apple Silicon M1

Possible problem with context using the ARM 64bit download for Apple Silicon M1

[Keith McKay]

[-- Attachment #1.1: Type: text/plain, Size: 2765 bytes --]

Hi all

I have been using ConTeXt (X86 64bits) on my mac mini Apple Silicon M1 
and it works well using Rosetta translation for the M1. I recently 
installed the ARM 64bits version (separately from the X86 64bits 
version) which I assume does not require translation using Rosetta. 
However I had a error with the lmt_shade command in the ARM 64bits 
ConTeXt verson but not in with the X86 64bits version of ConTeXt. The 
MWE is shown below. This is actually taken from the LuaMetaFun manual. I 
also noticed that some figures are missing in the manual (Chapter 7, 
Shade) which is part of the ARM 64bit tree but not in the manual in the 
X86 64bits tree.

Best Wishes

That arm version was an experiment so it's definitely not in sync with 
the latest luametatex/lmtx combination. It was crosscompiled on an intel 
mac which took ages so it stuck as experiment. Because th eintel bin 
runs on the arm mac it has a low priority (unless someone donates an arm 
mini to the farm). So, forget about the arm apple bins for now.

We do generate windows arm but that's because it's easy to do, boit that 
we have a machine to test if it actually works.

Btw, in the latest upload the metafun manual should compile ok (Otared 
tested till we had all working in lmtx which does some things 
differnetly deep down; there were also some resources missing).

Thanks for your reply Hans.

I half suspected that the ARM version was experimental but thought I 
should report it anyway.

Much as I would love to donate an ARM mini to the farm the best I can do 
is offer to compile on my mac mini Silicon M1, however, I would have to 
add the caveat that this is something I have never done so would need a 
lot of hand holding.

Best Wishes

it would mean opening up your machien to mojca, adding it to the compile 
farm etc etc .. not a good idea, keeping it running 24/7 because we 
cannot afforc to miss a binary ... so we just wait till these arm 
machines make in into our homes .. no hurry i guess

Are the source files and test cases in a Git / Mercurial / Fossil / whatever repository somewhere? It would be easy enough to set up an automated daily check to see if there had been a change and then trigger a fresh build.

It doesn't even need to be that integrated - just a check on the latest intel binary and if that has been touched then trigger a download and local compile.

If Keith's scripting skills aren't up to it then I could do it and then developer sign and upload the resulting binary to OneDrive or similar.
