you should not need to use that. it's only needed if you remove the
existing copies of mk, iyacc, etc. in Linux/386/bin, which are included
in the svn copy.

>but i noticed some trouble with X11, etc.

ah. you probably have not installed various `developer' packages for X11 for Ubuntu.
not Inferno-related, but Debian packages that anyone needs on Debian/Ubuntu
to compile X11 applications.  ie, packages you select and install through
apt-get  or synaptic.

afd for sys->mount(2)

Hi!

mount(2) says:
 mount: fn(fd: ref FD; afd: ref FD, old: string, flag: int, aname: string): int;
 ...
 If the requested service requires authentication, the file descriptor afd
 must be open on an authentication file for the requested service;
 otherwise it should be nil.

But looks like mount(1) always set afd=nil, even when authorization used.
And I don't found any other app which use afd param.

How it was supposed to be used?
Why it isn't used now?
Maybe man page should be updated to explain current situation with
authorization in mount()?

hi all,

here is the update.

looks like it needed the package libx11-dev. once I installed it,
things were okay.

next, my machine has Core 2 Duo, so I was wondering if i should try
64-bit ubuntu. ubuntu came up fine but inferno didnt build there. i
didnt dig into the details but i thought there may be a 32-bit mode
which will take care of the disparity that inferno needs a 32-bit
architecture.

i have seen an error with graphics mode at least twice. i start emu as
given below and then i click on Start button and then the graphics
screen dies.

I've seen this sort of thing on FreeBSD as wel, but without
tk complaining about a font.  In my case it's been when I
start acme.  It started after an upgrade to the latest xorg.
So it looks like they changed something that breaks Inferno,
but I haven't had a chance to try to track it down.

hi,

i copied fonts from vitanuova's inferno release and then it seemed to
be better but i just noticed an issue: this time it is a graphics
screen freeze and i see this message:

dharani <at> dharani:~/inf090226_1130am$ emu -r. -g1500x1100
; ndb/cs
; wm/wm
emu: ../../src/xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int)
((xcb_req) - (dpy->request)) >= 0)' failed.

any clues? appreciate any help.

thanks

Re: afd for sys->mount(2)

mount will use the afd if the -9 option is given,
causing its use of Sys->mount via Factotum->mount to
have a non-nil afd, the result of a call to sys->fauth.

hi,

irrespective of screen size, graphics screen crashes with this message
either during start or once i start acme or so:

; ndb/cs
;wm/wm
tk: font not found: /fonts/pelm/unicode.8.font
emu: xcb_out.c:301: _xcb_out_flush_to: Assertion `((int)
((c->out.request_written) - (request)) >= 0)' failed.

any clues? currently, inferno is almost unusable.

thanks

Re: Fwd: linux distribution

This happened to me too on Linux: on Debian 5, Slackware 12.1,
OpenSuse 11. It seems that new Linux distributions tries to replace
Xlib with XCB (http://xcb.freedesktop.org/). On Debian 4 Inferno
graphics works fine. I think the Inferno graphics code should be
adapted to XCB.

It's not so much a matter of adapting the code to xcb
as just making code using the old interface make sure
that each Display* is only used in its own thread.
I did this for plan9port and 9vx.  It required a little care
but was not hard in the end.  The old, buggy code could
have crashed the old xlib too, it just would have been
a little harder.

There's not much point in moving wholesale to xcb
when the xlib version would still have to be maintained
for non-xcb systems and the xlib interface suffices
for this purpose.
