I'm unable to run squeak

Hello, I have IBM ThinkPad T42, Gentoo with Linux kernel
2.6.14-gentoo-r2, using gcc 3.3.6. I have tried binary version,
compile vm from sources (downloaded from
http://www.squeak.org/Download/ - it is version 3.7.7) and finaly also
install older version from portage. Always I get this:

$ squeak Squeak3.8-6665full.image

Before segmentation fault for very short moment window is displayed.
I'm attaching strace. Any idea how to make seqak working on my
computer?

Thank you

I don't know why you're having that problem - but there is an updated ebuild for
that version of the VM that went in yesterday. It's in the unstable branch, so
you'll need to put these lines into your /etc/portage/package.keyword file:

dev-lang/squeak ~x86
dev-lang/squeak-basicimage ~x86
dev-lang/squeak-fullimage ~x86

(you can choose whether to use basicimage or fullimage)

Then emerge squeak. Note that there's a problem with the current ebuild in there
where if you've got the "threads" USE flag enabled, the compile will break. This
has already been fixed by the developer though, and should be OK by tomorrow. In
the meantime, doing:

#USE="-threads" emerge squeak

Should get you a working squeak instance, hopefully without segfaults :) It
certainly works for - although I'm using a 2.6.x kernel version (which may be
your issue).

You may want to try :

$ squeak -memory 200m Squeak3.8-6665full.image

or

$ squeak -mmap 200m Squeak3.8-6665full.image

Thank you, but new version of ebuild didn't help. I have tried play
with CFLAGS but I still get same segmentation fault.

> $ squeak -memory 200m Squeak3.8-6665full.image

Still same result. I have tried change how many memory to use but
seems it's not reason of my segmentation fault.

Thenks for advices

Now, I'm not an expert Squeaker as such. Try:

- Making sure that Squeak isn't trying to load plugins from elsewhere
than where it is meant to load them. This is a bit tricky; there are a
few places it (iirc) looks automatically. Delete them all? Rename them?
You use Gentoo, so I assume you're smart enough to work out how. In my
experience, applications loading the wrong libraries crash.

- Do you have any "odd" files in the current working directory? Try
running squeak completely from a single directory (including plugins,
image and executable).

- Are you using a 64-bit build? I'm seeing stat64() in the strace, so it
seems so. Have you tried making a 32-bit build instead, or downloading
the 64-bit VM (google for it... I'm too lazy to find a link)?

(wow... squeak looks *really* hard to find its plugins!)

The strace also has a stack trace at the end which appears to be trying
to make a snapshot? This I don't understand - it should only happen if
you save and quit the image.

I also see that neither the FilePlugin or the SecurityPlugin are found.
Do you have your plugins configured correctly?

Otherwise I'm afraid you'll have to wait until somebody who knows stuff
can help you.

nax@naxbook ~ $ squeak -version

From strace I can see which directories are searched for plugins (I
can't rename /lib or /usr/lib, but there isn't any file loaded
according to).

No, I have tried run it from empty directory with single image and it
fail in same way.

No, I have ThinkPad T42 with mobile centrino (Pentium M) which is
32bit architecture. Even if I have some wrong configuration and
building 64bit VM why then fail this binary distribution
http://ftp.squeak.org/current_stable/unix-linux/Squeak-3.8-6665-i686-pc-linux-gnu-3.7.7.tar.gz

I don't have an idea what does this mean, but Squeak never ever
successfully run on this laptop. I have installed VisualWorks, but
Squeak seems to be more confortable for me. That's why I really want
to run Sqeuak and learn smalltalk in this environment.

>I also see that neither the FilePlugin or the SecurityPlugin are found.

I don't thing that I have any plugins installed except that comes with
ebuild or standard installation (any FilePlugin or SecurityPlugin it
didn't installed).

Today I have noticed that better mailing list for my problem will be
wm-dev so thanks for all advices on this list.
