Thanks Levente. Unfortunately it did not work:<br>
<br>

Seems like you have to build it yourself. Fortunately it's very easy,<br>
since Eliot commits the generated sources to the svn repo. So you can<br>
build a CogVM/StackVM without VMMaker. Here is how:<br>
<br>
"How to build the Cog Croquet VM on Unix<br>
-------------------------------<br>
1. Install the tools (gcc, X11-devel, etc (e.g. libpng, libX11 & libxt<br>
source))<br>
2. Check out the following sources from svn (if you haven't already<br>
- if<br>
you're<br>
reading this in unixbuild its likely you've already got the sources)<br>
svn co <a href="http://www.squeakvm.org/svn/squeak/branches/Cog/platforms" target="_blank">http://www.squeakvm.org/svn/squeak/branches/Cog/platforms</a><br>
svn co <a href="http://www.squeakvm.org/svn/squeak/branches/Cog/src" target="_blank">http://www.squeakvm.org/svn/squeak/branches/Cog/src</a><br>
svn co <a href="http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild" target="_blank">http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild</a><br>
3. Open a shell, cd into the unixbuild/bld directory and execute<br>
../../platforms/unix/config/configure CFLAGS="-g -O2 -msse2<br>
-D_GNU_SOURCE -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1<br>
-DCOGMTVM=0" LIBS=-lpthread<br>
make install prefix=WhereYouWantTheVmToGo<br>
4. At the end of it you'll get a new VM in the path provided via<br>
-prefix"<br>
</blockquote>
<br>
Are there any additional requirements like gcc version, for instance?<br>
<br>
I ask because I get errors on the above instructions, on FreeBSD 6.4,<br>
running gcc 3.4.6. I can attach configure's output and whatnot, if<br>
you're interested.<br>
</blockquote>
<br>
If configure failed, then please attach the output and continue this<br>
thread on the vm-dev list.<br>
</blockquote>
<br>
I didn't expect the instructions to work, since FreeBSD isn't Linux. So<br>
having said that, I've attached the output from configure (which looks<br>
fine, to my untrained eye) and the output from make install (which<br>
generates errors).<br>
<br>
That first error:<br>
<br>
In file included from /usr/home/frank/temp/src/vm/gcc3x-cointerp.c:21:<br>
/usr/include/malloc.h:3:2: error: #error "<malloc.h> has been replaced<br>
by <stdlib.h>"<br>
<br>
is probably the culprit, I suppose?<br>
</blockquote>
<br>
Yes, maybe I'll learn to hack a bit first. If I manually edit gcc3x-cointerp.c and replace malloc.h with stdlib.h, compilation does indeed proceed much further. </blockquote><div><br></div><div>Then the code needs to read something like</div>

The low-space watcher is running, at least before the problem<br>

<br>
In which case you want to do the following:<br>
* Launch your app and wait until it's in the "growing state"<br>
* Hit F2 and from the VM's preference menu choose "Debug" and then<br>
"Print all processes"<br>
<br>
This will dump a list of all the call stacks of all processes. One<br>
of them is the culprit consuming memory and you'll probably be<br>
able to tell quickly from just looking at it (if not, you can<br>
email the output here but it typically takes a domain expert to<br>

Thanks for this pointer, Andreas.<br>

This time it was a Cog VM which spasmed, which I use for my client<br>
(Squeak 4.1 for server for use with linux vm - I have no ability to<br>
compile a linux Cog vm: would love if someone posted one that could<br>
be launched headless for my webhost).<br>
</blockquote>
<br>
Cog works, but i think you're trying to use the -headless switch,<br>
which (is deprecated) and tells the vm to use the X11 display, but<br>
with no window. Servers usually don't have X11, so it won't work.<br>
You better use -vm-display-null (and -vm-sound-null). Try squeak<br>
--help for further useful options (like tuning Cog).<br>
<br>
</blockquote>
<br>
I am trying to use the -headless switch. Good to know it is<br>
deprecated. So you happen to have a Cog for linux binary (version 17<br>
- 20), which I could use?<br>
</blockquote>
<br>
I have one, but I'm not sure it will work on your server. You can find<br>
it here: <a href="http://leves.web.elte.hu/squeak/cog17.tar.gz" target="_blank">http://leves.web.elte.hu/squeak/cog17.tar.gz</a> . It's built on<br>
ubuntu 10.04 and is optimized for core2.<br>

It started running at 100% and I did your F2 -> Debug Options -><br>
Print all processes. It started dumping a LOT to the Debug Console,<br>
then it froze, still at 100%, but no increase in memory now and it<br>
went (Not Responding) and greyed out the window.<br>
<br>
Luckily, I was able to see enough of the stack that was causing<br>
problems. It is infinitely looping in this method:<br>
<br>
LanguageEnvironment class>>#localeID: localeID<br>
^self knownEnvironments at: localeID ifAbsent: [self localeID:<br>
(LocaleID isoLanguage: 'en')]<br>
<br>
This has nothing to do with my code, except I must be calling<br>
something that enters this loop. It happens in both Cog (Windows)<br>
and Squeak4.1 (Linux <headless> and Windows).<br>
<br>
Not sure how to fix this.<br>
