I'm using FreeBSD 11.1.  Things have changed a little since
they switched from gcc to clang.  I'm also running on an am64
install.

First, I had to rebuild mk.  The supplied binary expected the
libc shared library to be named libc.6.so, but the one present
on the system is just libc.so.  In doing that, I found there was
no setfcr-FreeBSD-386 source file.  Copying the Linux one
made it possible to build lib9.  Now I'm fighting with the floating
point stuff.  None of the FP constants are found.  I seem
to remember running into the same thing last year and did
eventually sort it out.  The other problem then was that a
couple of the X libraries weren't part of the 32-bit support
and I could only build emu-g.

I haven't thought about anything along those lines with the
hosted versions, but a while back I did start putting together
a bootable live CD running natively.  Graphics were limited
to standard VGA (640x480x16 IIRC) and I ran out of momentum
when messing around with Ethernet drivers on older laptops.

For a hosted version, as long as you only targeted various
Unices, you could probably have a shell script that figured
out which emu to run based on the output of uname.

Until now I did not have a need for this, so I do not know.
But often there is a need for a compact live VM with a ready OS that
must be run on a public terminal. This is a problem. Live USB I can
not load to the terminal, it forbidden. I found only Puppy Linux in
the Virtual Box, but it works very slowly.

I many times used Inferno on the desktop in the past, but I had
FreeBSD. It was usability. And here on Windows10x64 now the emu don't
start. It's a pity.

A modern OS to become popular should have a Live USB and ready-made
assemblies for almost everything. I'm sorry that Inferno does not have
a power now.

That reminds me. Weren’t there some Inferno ports for micro controllers, along 
the lines of the Arduino variants or their industrial counterparts?

Do you think that few people have heard about Bell Labs?
Almost everything. Read about and try about.

But every time when a new hands tries to take it and use it this is not

Programming on Linux is not at all like programming on Android, but it
did't stop the Android.
It's not because in Java, it because released powerful IDE and SDK

Now there is no diff what the language, they are created for almost every

And virtual machine too. Inferno is compact and beauty, it deserves to be

Some folks did put Inferno onto an Android phone:

I think part of what drives the directions many companies
take is how easy it is to bring new people on board to do
the development.  It's probably quite easy to bring in people
to program on a Linux based platform, easier than bringing
people in to learn an OS they probably haven't even heard
of.

Well, that is right, but not works yet

I'm a longtime admirer of the creativity of people from Bell Labs and
when there is an opportunity I try to study, use and promote Plan9 and
Inferno
For example, I did the version of Inferno for vending machines.
Unfortunately the company chose Linux
I don't understand why there is still no Inferno for smartphones, it
was sharpened for such devices

Lack of powerful integrated development tools is the main drawback.
Folks need IDE. Like VS Code. Or Anacode.
And also ready-made live distributions for launching from USB and
installing on a desktop with simple copying without admins privileges.

Now I have not even been able to install the Inferno on Win10x64. I'm
not admin on public terminal. I have no time and power to update and
fix it. I'm refugees.

I would very much like to see better times for both axes. So far they
are only donors of global and genius ideas and technologies

It works out to be the sweet spot where a lot of considerations come
together.  First, I like to teach OS from an internals point of view.  I
feel that one should understand how one's tools work before using
them.  Second, like a lot of people of my generation, the way I really
learned about operating systems was from Lions commentary on
6th Edition.  For years, I had been thinking about writing an OS text,
but had been teaching from Tanenbaum using MINIX.  It was getting
somewhat problematic in the days when no one was running VMs
for everything and students were getting to where they didn't know
how to partition drives and run other OSs.  Then when Vita Nuova
released the Inferno source, it was like all the pieces fell into place.
It's well-written and carries a lot of the same ideas as Plan 9.  Students
don't have to allocate any extra hardware or even configure a VM.
It's small and simple enough that we can cover all the major elements
of it as well as the general principles in one term.  But they're able
to get some exposure to the internals of a real system and not just
something created for illustrative purposes.

With the ubiquity of VMs these days, a good argument could be
made for using Plan 9 in a VM for the course.  Maybe someday
I'll look at adding Plan 9 chapters to the book, but at least for now,
I'm finding Inferno works quite well.

Don't go to any trouble on my account.  I'm at the same point
I usually am when getting ready to teach my winter term OS
course.  I've got it built, but without the X11 support on my
FreeBSD machine.  It does build and run on our Linux cluster
with the X11 support though, so I can at least demonstrate
it to the students there.

And for the record, the fix to the missing FPxxx constants
was to copy over the defines from the MacOSX version of
the lib9.h file.

I had given some thought to adding amd64 support in at
least the hosted versions, but as usual the round tuits have
been in short supply.

Re: [9fans] Inferno on Plan9

I used Inferno from bitbucket.org but wasn't able to build on FreeBSD 
11.x/amd64 so I just reverted back to FreeBSD 9.3/i386.  But I may try to build 
using 11.1/i386 with gcc.  I'll have to use KVM on OpenIndiana to try it though 
since I don't have a spare physical machine at the moment.

Which version of FreeBSD did you use, and did you use the

No need to run makemk.sh on Plan9. See INSTALL for details:

On Plan 9, of course, the host system's normal version of  mk should

I've installed Inferno on FreeBSD but how do you build it for Plan 9?  The 
makemk.sh file and without looking, I think the mkconfig file too, reference 
gcc.  And the makemk.sh has /bin/sh.  Do I have to install a Bourne or Korn
