Put milestones on opensmalltalk-vm, open new entries on opensmalltalk-vm issue tracker, put engineering force to solve pharo-specific build failures. In one word, help us to help you.

Maybe Truffle is a possible future for you, more solid than 100% own fork for sure.

I'm willing to help Pharo, I've helped producing Pharo brand 64 bits windows VM more than one year ago. I'm struggling to make the community beneficial to all, but I don't feel like I get a lot of support and wonder if I'm not completely mistaken when I see all the efforts deployed to tear it apart... > Stef > > On Tue, Nov 7, 2017 at 9:00 PM, Torsten Bergmann <[email protected]> wrote: > > Hi, > > > > by accident I stumbled upon the following code in > AnnouncementSubscription: > > > > makeWeak > > action isBlock ifTrue: [ self error: 'Not currently available due to > missing ephemerons support']. > > ... > > > > My understanding is that we have Ephemeron support in Pharo now working. > Right? > > > > Anyone with more insights who knows how to fix/complete this?
