[9fans] plan 9 ports to unix (including libdraw)

[9fans] plan 9 ports to unix (including libdraw)

[Russ Cox]

I've been using Unix (FreeBSD) for day-to-day work for a few
weeks now, and have started to bring over some Plan 9 tools to make
life a bit more hospitable.

Mk was already done, and Scott Schwartz did sam over the summer.

As I mentioned before, I did a fairly complete libdraw port
that is enough to compile samterm almost unchanged from the
current sources (the only real change was to use a named
pipe instead of /srv for the B file).

It has been working pretty well for me on FreeBSD and for
Rob on Mac OS X.  I tested it on Linux but haven't exercised
it very much.

This morning I compiled my crossword puzzle player without
any changes -- just worked (well, except for a little bug in the
libdraw port which I fixed).  I am hopeful about other things
compiling easily.

I'd love to see the plumber and acme made to work, though that
will require some reengineering to eliminate dependence on Plan 9
features.  I'm not likely to have time in the near future, though.
If anyone is interested and has time to hack, I'd be happy to do
a brain dump.

On a similar note, I have a 9P2000 drawterm that is very very alpha.
If you have time to bang on it, I'd be happy to share.  It's not
quite ready for regular use though.  Email me off-list.

I have a plumber that reads from a named pipe and is single threaded.
I'll post it when I get it to compile with your latest plan9 lib ports.

Thanks Russ for your porting Plan 9 tools.
I have downloaded and compiled.

It seems the absence of a directory plan9/lib causes
compile error.

Just for fun I tried compiling my xscr ports for linux/fbsd using your
plan9.tar.gz port...

Here's what I had to add in order to get them going, cvs diff against
the current repository (unchanged parts skipped):

both lrand and frand are from /sys/src/libc/port, with the definition of
'srand' in lrand commented out -- it just uses the unix libc one by default.

that was supposed to go just to russ, sorry...

ps: USED() in Plan 9 accepts more than one argument, USED() in unix' plan9
libs does not..

To avoid unnecessary duplication of effort, let me note that I'm very
close to having the unix ports running on sparc solaris.

It's been pretty straightforward -- most of what I have so far was
done in an afternoon.  Right now, however, my threads crap out on the
first call to a shared library.  I may have to spend some time
learning more about the dynamic linker than I ever wanted to know
(although, it's possible that I've simply misread the abi *again*).

If anyone feels like poking at it I can send files and diffs.

Kudos to Russ.  The ports are already making life better for me on
Linux/386.

I just hope we can settle on a definitive port.  I've done three
myself of the same bits (save for libdraw) and Russ has done a few
previously, too.  Every time I've thought it was much better than the
last, yet there's always another.

of late i've been assuming context of things i read a lot, and letting
that overwrite what the message actually says. it's caused problems. i
think my head's broke. so when i read:
   ...close to having the unix ports running on sparc solaris.
somewhere between my eyes and my brain "unix" turned into "plan 9". i
got *really* excited for a few seconds. :-(

I've managed to compile most of the port under cygwin.

cp Make.FreeBSD-386 Make.CYGWIN_NT-5.0-386

in libthread/label.h, change:
 #if defined (__i386__) && (defined(__FreeBSD__) || defined(__linux__))
to:
 #if defined (__i386__) && (defined(__FreeBSD__) || defined(__linux__) || \
 defined(__CYGWIN__))

cp asm-Linux-386.s asm-CYGWIN_NT-5.0-386.s

in lib9:
cp ffork-Darwin.c ffork-CYGWIN_NT-5.0.c
cp rendez-Darwin.c rendez-CYGWIN_NT-5.0.c
(cygwin provides pthreads, so I'm using that interface)

Compiling sam fails, though, with:
disk.o(.text+0x27c): In function `diskwrite':
/yadda yadda/plan9/src/cmd/sam/disk.c:108: undefined reference to `_pwrite'
disk.o(.text+0x31e): In function `diskread':
/yadda yadda/plan9/src/cmd/sam/disk.c:120: undefined reference to `_pread'

Haven't been able to test anything yet.

When a windows port is started, I'll try libdraw under mingw. Some of the
rest compiles, but I can't remember which parts.

Seconded.

Well I have now...

cd src/libthread; make tprimes
gives a slew of errors. maybe cygwin really doesn't have pthreads (though
the headers are there) or it could be a linker problem. I'm getting *lots*
of "undefined reference to foo" messages.

Anyone have better luck?

Re: [9fans] plan 9 ports to unix (including libdraw)

[Bruce Ellis]

you'll find somewhere in the cygwin pthread headers a comment along
the lines of "we don't really support pthreads because we can't swap
stacks".  i didn't look into it any further.

Speaking of ports -- I have had this idea for a long time to hack
xterm (or rxvt) and make them understand plumbing the way rio does.
It shouldn't be too hard, and I'm just curious whether somebody
else has thought of it already.

Comments ?

Thanks,
Roman.

rio doesn't understand plumbing

  sure it does -- otherwise you won't be able to select something
  and tell it "plumb this".

Maybe I should read the ported libs

Perhaps I interpret your 'understand' too deeply.

#include <plumb.h>
Plumbmsg *m;
m = emalloc(sizeof(Plumbmsg));
.. fill m
plumbsend(fd, m)

[9fans] ppp modem connection

[John P. Cummings]

hi-

i'm having problems setting up a ppp connection.  i'm using a xircom
56k pc card modem on my thinkpad t22.  it didn't seem to be recognized
at first, so i went ahead as if i knew what i was doing and added
"XM5600" from it's idstr to the list of modem in pcmciamodem.c.  it
seems to work, the modem is recognized, and i can dial out.  i think
my problems are related to my ignorance of network configuration in
plan9.  here is some random output from my attempts, if i can send
anything else, please let me know.
