Thanks for the pointer to the ZeroConf. This is my first time using that. I'm used to the usual Ubuntu installation which provides a pharo-vm-x (GUI) and pharo-vm-nox (headless). The command line functionality is cool, but that's not what I want. By playing around, I figured out how to get --no-quit to work. I was trying ./pharo --headless --no-quit ./Pharo.image & and I needed ./pharo --headless ./Pharo.image --no-quit & I guess that makes sense knowing that --no-quit is actually to be processed by the script and not a flag for the VM. Anyway, I think I got it figured out. Thanks for the help, Jeff On Sun, Feb 15, 2015 at 9:34 PM, Sven Van Caekenberghe <sven@stfx.eu> wrote:

Fine.
All the ./pharo does is redirect to the vm with the --nodisplay flag.
So ?
When I try it without the "eval "ZnClient new get: 'https://google.com'"" part, I get the following in the terminal:
Usage: [--no-preferences|--preference-file=<FILE>][<subcommand>] [--help] [--copyright] [--version] [--list] [ --no-quit ] --help print this help message --copyright print the copyrights --version print the version for the image and the vm --list list a description of all active command line handlers --no-quit keep the image running without activating any other command line handler <subcommand> a valid subcommand in --list
Preference File Modification: --preference-file load the preferences from the given <FILE> --no-default-preferences do not load any preferences from the default locations
Documentation: A PharoCommandLineHandler handles default command line arguments and options. The PharoCommandLineHandler is activated before all other handlers. It first checks if another handler is available. If so it will activate the found handler.
Then pharo exits. It seems like it is just doing the command and then dies.
Yes, Pharo runs and exits because you do not tell it what to do, like any command line utility. Try --list to see all the options.
That's definitely different behaviour than a usual headless pharo.
I don't understand what you are referring to. This is the way it works with the so called Zero Config system, since quite a while, maybe this can help:
http://pharobooks.gforge.inria.fr/PharoByExampleTwo-Eng/latest/ZeroConf.pdf
(which might not be 100% up to date, I did not check, but it should help).
But the point is, what I said before works perfectly, why go look further ?
What is your concrete problem ?
Cheers,
Jeff

./pharo is the headless version ./pharo-ui is the version for running a GUI
these are both bash scripts that use the binary inside pharo-vm you can look at what's in them to understand what is going on
I don't want to be rude, but either you understand command line unix or you don't. To make things easier, there are the 2 top level scripts. I have no time to explain this from first principles, sorry.

This somewhat works. At minimum, the command for downloading the google home page works. On the other hand, the pharo-ui line caused an error: "pharo: could not find any display driver"
That's not a huge deal as this is on a remote server and I can run headless. However, when I try to do that (i.e., ./pharo-vm/pharo headless ./Pharo.image &), I get the same message about not finding a display driver.
I do get both vm-display-X11 and vm-display-null showing up as available drivers.

It seems some people are having trouble getting Pharo to work on Ubuntu 14.04.1 LTS 64-bit.
Here is one way to make things work.
Pharo (the VM) is a 32-bit executable dynamically linked to a number of libraries, each of which has to be present in its 32-bit variant in order to run Pharo and/or to use all features.
On a clean, stock, fully updated Ubuntu 14.04.1 LTS 64-bit, do the following (the X11, GL and asound libraries are not needed when you run headless on a server):
$ sudo apt-get install curl libc6:i386 libssl1.0.0:i386 libX11.6:i386 libGL.1:i386 libasound2:i386
$ curl get.pharo.org/40+vm | bash
$ ./pharo Pharo.image eval "ZnClient new get: 'https://google.com'"
$ ./pharo-ui Pharo.image
HTH,
Sven
PS: <Pro tip> You can use ldd to check if all dependencies of the VM and its plugins in the pharo-vm directory are satisfied
