Re: [Pharo-dev] Deployment process for Pharo :)

by Mariano Martinez Peck

I saw his presentation and I very much liked him showing that. It shows at least the first steps someone could follow in order to provide a "self contained" app that could be download and run with double click in Unix/Windows/Mac. As always, it may not be 100% complete, but really a good step forward that worth sharing with the community.

I didn't send a mail to the mailing list because I was not able to find a small reproducible test case. Maybe it is the same case as this one since my final thought was that it was a compiler problem and not VM. Marcus, do you think a workaround could also be applied to 4.0? If true, I can check if that solves my crashes or otherwise keep trying to see if I find a smaller case. Thanks! -- Mariano http://marianopeck.wordpress.com

The method icon is that of a #halt for now for active breakpoints. I improved the Nautilus integration: the icon is now a button. If clicked, the breakpoint is removed. Marcus

It correctly eliminates the unused block, but it *should* emit a return self instruction (as it would for a method with an empty body), but it doesn't, which is why the VM crashes. Cheers, Henry
