Thanks! That worked.

I guess the build/dist/pharo-vm/resources/img.image - which I thought would be a minimal functional image - isn���t. I was trying to get the startup .st code working first, and didn���t try any other image.

I get a bunch of stderr log messages about
��Cannot locate any of #('libgit2.1.4.4.dylib' 'libgit2.1.0.1.dylib' 'libgit2.1.0.0.dylib' 'libgit2.0.25.1.dylib'). Please check if it installed on your system

but I can ignore those easily enough.

Thanks, now I can get to my experiment.

Sure, but I���d need a bit more of information from your side, because from my side, I just compiled latest version and did:

# Compile VM

$ git clone ��� repo

$ cmake -B vmbuild -S repo

$ cmake ���build vmbuild ���target install

#Download a pharo 10 image

$ wget -O- https://get.pharo.org/100 | bash

#Create your script

$ tee -a hello.st << EOF

Transcript show: 'hello world!!';cr.

EOF

$��./build/build/dist/Pharo.app/Contents/MacOS/Pharo Pharo.image st hello.st --save --quit

hello world!

Hi Guille,

I���m just trying to run the img.image that comes with the pharo-project install.

All I want at this stage is to execute `Transcript show: ���hello world���;cr.` (and have that show on std-out or std-err) and exit.

Hi Dave,

a couple of quick hints that could lead us to a solution:

- what image are you running on top? what version?

- is the image source file close to the image/VM?

- if the process seems frozen, you can send it the SIGUSR1 signal so it dumps a log of the execution

�� ��kill -SIGUSR1 pid

That dumps��

��- the native stack

��- the smalltalk stacks

That would show you quickly where the problem is, very probably there is an infinite recursion in pharo code.

Hi,

I���ve built a stackVM straight out of the box from the instructions at��https://github.com/pharo-project/pharo-vm��to run some experiments. So I���m trying for a simple Hello world on stdout/stderr. I assumed on headless Transcript would go to some useful place, so I tried,

I have a hello.st
-----
Transcript show: 'hello world!';cr.
"(Smalltalk at: #Transcript) show: 'hello world!';cr."
-----
and run-test:
-----
#! /bin/sh
#
# Run it with a headless Pharo:
#
DIR=~/git/pharo-project/stackVM/build
VM=$DIR/vm/Debug/Pharo.app/Contents/MacOS/Pharo
#IMAGE=$DIR/dist/pharo-vm/resources/img.image
IMAGE=img.image
ls -l $VM $IMAGE
grep . "$@" /dev/null
set -x
$VM -vm-display-null -headless --logLevel=4 $IMAGE "$@" --save --quit
-----

and I get:

and 40 minutes later it exits having been kill -9���ed

Once, it exited quickly, but I have no idea what was different that time. Also ���save does seem to do anything.

If it reliably exited, I could experiment, but I have no idea what���s happening.

Help! (and Thanks in advance)
