Eliot,
I am on 8 of these puppies. I'll try -m32 in the CFLAGS and let you know....after my doc appt. Rob

I have attached the error from make install...
/home1/vawhigso/public_html/squeakelib/Cog/platforms/unix/vm/sqUnixHeartbeat.c:161:3: error: #error "no high res clock defined"
If you look at the code the error is pointing you at:
#if defined(__GNUC__) && ( defined(i386) || defined(__i386) || defined(__i386__) \
|| defined(i486) || defined(__i486) || defined (__i486__) \
|| defined(intel) || defined(x86) || defined(i86pc) )
__asm__ __volatile__ ("rdtsc" : "=A"(value));
#else
# error "no high res clock defined"
#endif
you'll see the system expects an x86. Are you on an x86-64? If so you need to specify something like -m32 in the CFLAGS and/or supply a flag with te same semantics to configure.

Thanks Levente. Unfortunately it did not work:

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

In which case you want to do the following:
* Launch your app and wait until it's in the "growing state"
* Hit F2 and from the VM's preference menu choose "Debug" and then
"Print all processes"
This will dump a list of all the call stacks of all processes. One
of them is the culprit consuming memory and you'll probably be
able to tell quickly from just looking at it (if not, you can
email the output here but it typically takes a domain expert to
understand what's going wrong).
Thanks for this pointer, Andreas.
This time it was a Cog VM which spasmed, which I use for my client
(Squeak 4.1 for server for use with linux vm - I have no ability to
compile a linux Cog vm: would love if someone posted one that could
be launched headless for my webhost).
Cog works, but i think you're trying to use the -headless switch,
which (is deprecated) and tells the vm to use the X11 display, but
with no window. Servers usually don't have X11, so it won't work.
You better use -vm-display-null (and -vm-sound-null). Try squeak
--help for further useful options (like tuning Cog).
I am trying to use the -headless switch. Good to know it is
deprecated. So you happen to have a Cog for linux binary (version 17
- 20), which I could use?
I have one, but I'm not sure it will work on your server. You can find
it here: http://leves.web.elte.hu/squeak/cog17.tar.gz . It's built on
ubuntu 10.04 and is optimized for core2.

Thanks,

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