If it works, then the information on http://bugs.squeak.org/view.php?id=7358 is probably valid for Cog as well as for the regular VM. If it does not work, then there is more to the problem and I'll reopen the issue on Mantis. As far as I know, there have been no reports of libuuid failures on the Unix VMs since Ian changed to using an internal UUIDPlugin, so this is an easy fix if it works for Cog also. Dave

Re: [Pharo-project] UUID and Cog?

by Eliot Miranda

...and if you want to try and make the UUIDPlugin internal you need to edit unixbuild/bld/plugins.int & unixbuild/bld/plugins.ext to move it from external to internal, then (if you've already configured) make reallyclean and repeat the configure step before making.

[Pharo-project] birthday party: who is coming?

by StÃ©phane Ducasse

Hi guys I will need to know who is coming. I told noury and luc so far that I will invite them later because else we will be too many. The idea is that we will have a buffet or something like that during lunch the saturday and play games, listen music.... the afternoon. Else if you want an idea for a simple gift.... I'm missing some dvd of Miyazaki :) Quentin knows and can probably be reached at QuenThi Ducasse <quenthi.ducasse(a)free.fr>. Stef
