I had to remove the VisionFive2[1] GUI packages before updating to a mostly
regular debian sid. This allowed me to more easily install the tools needed
to bring gForth up from source.

Euro800 for a 14" laptop? [Also uses StarFive JH7110 SOC]

Sorry for -ve view. When/if Imagination Technologies release the
driver source for the GPU the JH7110 SOC becomes very attractive,
and this would help lead to further rounds of development.

ISTR Anton installed RISC-V gForth a decade ago, but couldn't find post.

Interesting. So there's a Debian for the VisionFive2 (when we got our
VisionFive1, there was only Fedora). What conflicts are there between
the tools needed to bring up Gforth and the GUI packages?

We compiled Gforth on a virtual machine emulating RISC-V (RV64GC) in
2018 <***@mips.complang.tuwien.ac.at>.

In February 2022 we got a VisionFive1 (with Fedora 33), and built
Gforth on it <***@mips.complang.tuwien.ac.at>.

I clicked on all the links, but am still in the dark why I should
want this 140$ pcb?

Can I add my own instruction set to it, does it have FPUs, will it
do automatic differentiation?

Then you probably don't. We have the VisionFive1 to do testing and
development on RISC-V. But you can do it on an emulator as well.

Post by mhx
Can I add my own instruction set to it,

You can run emulators, but it's better (much faster) to run them on
your Ryzen or maybe a Raspi 5.

Post by mhx
does it have FPUs

Yes, but again, if you want FPUs, your Ryzen or a Raspi 5 will be better.

Post by mhx
will it
do automatic differentiation?

With the right software, sure.

A RISC-V version of ciforth for linux is available via
https://home.hccnet.nl/a.w.m.van.der.horst/lina.html
This is a linux version.
It has been tested on DongshanNeZha STU board with only minor
shortcomings under Ubuntu 22.04.
