Headless Squeak on Redhat - HELP!

I have a small (P3) server running Redhat, and I'm
trying to get Squeak running on it. Since there's no
monitor, and the graphics subsystem isn't started in
the usual runlevel, I need to run Squeak headless.

I put image and change file into a directory (read,
write, owned by user A) that should copy a couple of
files when run, using Smalltalk addToStartUpList:
MyClass. I load it up in Windows, and it works fine.

I load it in Linux:
[root@myserver A]# squeak -headless

The cursor goes to the next line, and nothing happens.

Any idea what's going wrong? How do I correct it? I
will happily furnish any other info or troubleshooting
that is needed.

THANK YOU!
Albegadeep

Unfortunately all our psychics are busy working out the Lottery results for me for this coming Saturday, so you're going to have to do some diagnosis yourself :-P.

It sounds like your image is starting up fine; a cursor on the next line is all I'd expect. Have you checked to make sure the files aren't actually been copied and that everything is working fine? Have you checked the obvious things, such as running it in headless mode under your development environment (your Windows machine) to see if it behaves the way you expect?

My initial suspicion is that something platform-related isn't working - permissions, directories that don't exist, the current working directory is wrong, a plugin is missing, or something like that.

I can think of several paths forward. Either:

- Use OSProcess to write debugging information to stdout, or a logging solution like writing directly to a log file or using Toothpick.

- Install VNC on the image and access it from another host to diagnose the problem.

- If the X11 libraries are installed on your server, grab the Cygwin X server and ssh client, "ssh -X" to your linux server and run Squeak with the GUI that way.

- Use REPLServer (which I wrote, so I'm biased ;-) ) to access the remote image and work out what's happening.

I'm assuming you're able to find each of these packages using Google and common sense.

Hi,

unfortunately I can't help. But I'd like to take the chance to maybe get an answer to a similar problem.

I got a virtual server running with a Suse 9.3 Linux. Usually there's no X11 installed (but I tried so some month ago, just to see whether this helps with my problem).

I never got Squeak running headless. I always get a segfault. I tried it with different vm, I think the current one is compiled from svn.
Compiling the vm and all that works. Now today upon that mail I tried it again and it looked a bit more promising, but still I don't get it running.
On my local Linux I got no such problems, even though this usually makes more trouble due to being a 64bit machine.


Now, if I use the default image, installed with inisqueak in some directory and try to start it with

squeak -vm display=none

I get the following output (I was already quite happy about that in an awkward way as usually I see much less :)

-----------------------------------

using as command

squeak -headless

I get

>
Segmentation fault

-2126831928 UndefinedObject>?
2142441752 ByteSymbol>?
Speicherzugriffsfehler

------------------------------------------

if I use the sq3.9-7067web07.12.1 image, where I initially tried to start VNC in order to use the image once running remotely I get with

squeak -vm display=none sq3.9-7067web07.12.1.image

the following

>

-2128125960 UndefinedObject>?
2138702056 SmallInteger>?
Speicherzugriffsfehler                       --> memory access error

-------------------------------------------

but with

squeak -headless sq3.9-7067web07.12.1.image

I get again the one from above with -vm display=none and the other image. Which doesn't make too much sense to me
as -headless is supposed to equal -vm display=X11 -headless, what would make sense to not work correctly as
I either don't have it installed or at least not working correctly.

I hope this is just a silly error on my side. Maybe somebody can help me.

Thanks for any help.

Can't help with the seg fault, but in any case your image tries to  
open the sources file and fails.

You should disable the warnIfNoChangesFile and warnIfNoSourcesFile in  
production images.

This might very well be the case for Albegadeep, too.

Something that might help diagnosing (not in this case, but for Unix  
deployments in general) is to log errors to stderr. I added this to  
the OLPC version recently:
