Problem with installation of Octave

Arjen Markus
Hello,

when I updated my installation of Cygwin with Octave (4.2.2 to be
precise) and tried running it (while having an X server running), I
ran into a problem with D-bus:

D-Bus library appears to be incorrectly set up; failed to read machine
uuid: Failed to open "/etc/machine-id": No such file or directory See
the manual page for dbus-uuidgen to correct this issue.

Apparently, installing Octave was not enough, I had to install D-bus
separately. When I had done that, the problem was gone. I guess this
is an omission in the dependencies for Octave. Note: this problem
occurred both with and without the GUI that Octave comes with (octave
--no-gui gave the same error messages).

Kind regards,

Arjen Markus

Hi Arjen,
noted, however I see that dbus shoud be pulled by xinit

Are you using the X server without xinit ?

Regards
Marco

Re: Problem with installation of Octave

I checked the various packages that I have installed regarding X:

libX11-devel, libX11-xcb1, libX11_6, libXau-devel, libXau6,
libXcomposite1, libXcursor1, libXdamage1, libXdmcp-devel, libXdmcp6,
libXext6, libXfixes3, libXfont2_2, libXft2, libXi6, libXinerama1,
libXmuu1, libXrandr2, libXrender1, libXss1, libXtst6,
libxcb-composite0, libxcb-devel, libxcv-ewmh2, libxcb-glx0,
libxcb-icccm4, libxcb0image0 (and some other X-related libraries, just
skipping them, as they seem not to add more information), xauth,
xcursor-themes, xkbcomp, xkeyboard-config, xorg-server,
xorg-server-common, xorgproto.

There is no command "xinit". I start the X server using the command
"X" and that seems to work fine. However, I do see a pacakge xinit now
that I explicitly look for it.

Regards,

Arjen

Re: Problem with installation of Octave

Jay Abel
I'm using tcsh and for some reason the default configuration for X11 keeps
leaving zombie dbus processes, none of which seem to be reachable.  For
example, when running Octave I get an error that dbus wasn't replying.  Now,
if within the open xterm window I type dbus-launch and then I run octave,
there is no error.  I noticed that running dbus-launch in the xterm window
creates three environment variables beginning with DBUS_ but the default
startup only creates the first one, DBUS_SESSION or some such.

Any idea what I'm doing wrong?
