amd64 native VM missing from SDKs

I wanted to play around with croquet but I haven't found a 64bit VM in
either of the SDKs that I have downloaded. I have a amd64 squeak VM,
but it isn't linked to the OpenAL libs so it segfaults on OpenAL's
createContext. (With my squeak vm, the networked version outputs:
SocketPlugin: ignoring unknown option 'SO_REUSEPORT'
and then throws a two zero divide errors in squeak. It doesn't go any
further)


I do not want to install 32bit libraries, but I'd be willing to do a
/little/ VM hacking if it hasn't already been done. The problem is
that I can't find the vm sources (are they in monticello?) and I'm not
really familiar with slang or monticello. When I got the 64bit squeak
vm working on this machine, I basically just modified C code from a
subversion checkout using a few patches from the internet.


thanks

Sources are at squeakvm.org - be sure to read the 64 bit FAQ first:

ok I didn't realize that the croquet and squeak vm used the same
source code base. Because that version seems to be too old to run
croquet, I rebuilt my squeak vm using the latest subversion sources:

It also seems I still get zerodivide errors from:
Float>>/
Float(Number)>>roundTo:
Scrollbar>>setValue:
PluggableListMorph(ScrollPane)>>hSetScrollDelta
PluggableListMorph(ScrollPane)>>extent:

which make it almost impossible to use the system browser.


When I run it under gdb, it acts a little different but it still
crashes after I try to drag out the simple world and cancel the
emergency evaluator
