Re: [Newbies] Re: problem with big dictionary
Thanks for this workaround - it works now. But highest value for -memory parameter is 880MB (on my Ubuntu Linux). If I try greater value than 880MB, squeak falls down with message: bad address: negative. pf Klaus D.

Petr, yes, there seems to be a limit = 1GB in the 32bit VM's. It is perhaps possible to bypass the problem by using the -mmap argument but I have no experience with that. Perhaps you find a more recent VM executable which fits: - http://www.squeakvm.org/unix/ IIRC 1GB of memory is addressed in the 64bit VM's. /Klaus On Wed, 18 Oct 2006 17:23:00 +0200, Petr Fischer wrote: Thanks for this workaround - it works now.
