I assumed nodejs is C++ software that would compile on any Linux arch, but I guess the V8 Javascript engine does some low-level stuff that needs be ported to every CPU architecture. The V8 Website mentions: x86, Arm, MIPS, PPC64, s390, RISC-V and Loong64. Not much support for legacy or big-endian platforms.
Not much support for legacy or big-endian platforms.
All PPC, most MIPS and some ARM systems are big-endian.

I've read that some or all ARM chips can be switched to work in either mode.

All three architectures are big-endian AND little-endian.
Unfortunately nodejs will most likely never run on m68k.

Yeah, MIPS processors are like that too, but while in my experience
most ARM systems run little-endian, most MIPS systems run big-endian.

I've written code for a lot of PPC-based systems, not one has ever been little-endian. I do see they now exist, but appear to be pretty rare.
Similarly, all the MIPS-based systems I've developed for have been big-endian.

I'm glad you did. I was not aware that nodejs / V8 is so damn picky
about the CPU. I thought it would compile on any Linux / BSD. But unfortunately that is the way the web devs / companies are heading for quite some time. Creating libraries and web sites / apps on monstrous JavaScript frameworks. Wasting so much resources that you need very performant JS engines and faster computers. They don't see why you want
to run nodejs on legacy devices, especially not on very very old retro computers like an Amiga ;).
The problem with V8 is that it's
jitting to native object code; so unless you've got a backend
for that, it won't run on your platform.
I'm a bit surprised there isn't a fallback to either a
portable p-code or just straight-up interpreter.

The chance of that might increase if there is already a Spider Monkey (Javascript Environment) available on M68K?
Which SpiderMonkey version is required? Wiki says 1.8.5 for 3.16 IIRC. Older versions are in Debian, newer versions don't build on m68k AFAIK.

I don't see why it wouldn't, provided you can find a recent
enough OS and toolchain. The problem with V8 is that it's
jitting to native object code; so unless you've got a backend

I'm running the following, and as others have now posted java/javascript is the limiting factor now.
Linux m68k 6.1.0-1-m68k #1 Debian 6.1.4-1 (2023-01-07) m68k GNU/Linux "Debian GNU/Linux bookworm/sid"
Believe it or not, LE PPC exists!
So I hear! :-)
Is there a modern M68K system available (to buy) that'll run a
modern linux?

Certainly not as-is (we don't fully support any big endian targets
today). Is there a modern M68K system available (to buy) that'll run a modern linux?
Emu68 (the one for the PiStorm) is using the big-endian mode for it's
m68k emulation.
Linux m68k 6.1.0-1-m68k #1 Debian 6.1.4-1 (2023-01-07) m68k
GNU/Linux "Debian GNU/Linux bookworm/sid"
That's a pretty recent Linux, all right. I don't see why
the C++ bits wouldn't compile, but Digital Man would obviously
know a lot more than me about this.
Real hardware? There are some FPGA solutions and a bare metal emulator
on Raspberry Pi (Emu68, PiStorm). I doubt that they are a good
solution for running Linux.
The java bits would be the issue, and the Bit-wise of the code in Sync.

Synchronet uses Java? Or do you mean finding a suitable JavaScript
engine? Those two are rather different. :-)
I thought someone said that SpiderMonkey 1.8.5 was in the Debian
package repos for 68k Linux?

I said that, but I was wrong.
Ah. Too bad. I wonder how hard it would be to get it
to compile.

Just use the libmozjs-1.8.5-dev package (or similar) that's included
with the distro (if there is one), rather than trying to use/build the
one included in the Synchronet git repo.
