Hello,

browsing around I came across this board:

https://www.cnx-software.com/2021/11/27/visionfive-v1-risc-v-linux-
sbc-resurrects-beaglev-single-board-computer/


and cpu is Dual-core Sifive U74 RISC-V processor.

would lazarus work on that platform?

Thanks in advance.

AFAIK work is being done to support RISK-V, so  follow that.

Good news, nice card, right?

Right,
The compiler for riscv is also in trunk/main, so you can try it out.
If it is in trunk/main it means it is almost feature complete and open
for testing.
There are a few members who are interested, so keep following and

I wonder if anyone managed not cross-compile, but run Lazarus on
RISC-V

Granted, dektop computers are expensive now, like

But at least they are already possible.

My general experience looking- some years ago- at FPC and Lazarus on
various platforms was that once the compiler was OK Lazarus just
worked.

The issues tended to be (a) oversights in the compiler/RTL/FCL
makefiles where a particular library wasn't built for that platform
and (b) issues relating to endianness or alignment (most of which got
sorted when I was whining at the developers about SPARC support,
except possibly for an alignment issue in lhelp).

I definitely had Lazarus running natively on SPARC (Linux and
SunOS/Solaris), ARM (Linux on an NSLU2 "Slug") and possibly on MIPS
(Linux). The fact that it could be built and would run on a Slug,
albeit with lots of swapspace, suggests that it would probably build
and run on a Linux-capable RISC-V board which will almost certainly
have more resources... perhaps I should say /proportionately/ more
resources, allowing for the bloat that's affected almost all code over
the last ten years.

The availability of RISCV development kits for £10 and chips for
around $0.10 in quantity might be a game changer.

I'll report back when I have time, but if Dave can do it... :-)
