Is there a way to know if I am in iTimer VM?

Guys,

As you know, OSSubprocess does not work correctly in Linux unless you use the iTimer VM. I would like to open a warning (that growl thingy on bottom left of the screen) or something at loading / install time if I can detect I am under Linux AND under traditional linux VM (not itimer).

Do you know how can I do that?

The --version command line option to the VM prints "ITHB" as part of the version for itimer VM's. Not sure whether that is accessible from within the image though.

Cheers,

Max

OK... yeah, I don't know if that's accessible to the VM.

And related questions... could it be that for 6.0 the "default" linux VM is now threaded heartbeat rather than itimer? That looks like based on [1].

Also, for Pharo 5.0 which is the official place to download the threaded heartbeat Linux 32 bits VM?

Please can someone confirm?

Thanks in advance,

I thought it was the other way around, it doesn't work properly in itimer, only in threaded heartbeat?

Can't guarantee that to you.
Not unless the threaded-heartbeat-vm can be used hazzle-free (ie, without using sudo/..) ;)
