Hi, I may be wrong but it seems that CommonMusic is being replaced by Grace (and/or GraceCL). I have been using GraceCL on and off (I have not run cm proper in a while but when I did I never experienced segfaults). You can get grace(cl) here: http://sourceforge.net/project/showfiles.php?group_id=9766 but you need configured/compiled juce library in order to build it, instructions are included in the grace package. Oh and you can download a prebuilt binary of Grace and CM here (I think this one is at version 3.x.x): http://camil.music.uiuc.edu/Software/grace/index.html The package also shows you how to run cm as an inferior emacs process. I suppose your segfaults are related to the lisp implementation you use? IIRC CM works best with SBCL. But do not quote me on this, I have not been following the development of CM in a long time. So far I run GraceCL on Ubuntu 7.xx and 8.xx and it was all good for me (mind you, I have not tried any recent releases). I realize that I am not being very helpful, I figured I raise my hand as CM+ubuntu attracted my attention. Perhaps people on cmdist will be able to help: http://ccrma-mail.stanford.edu/mailman/listinfo/cmdist ./MiS On Sun, Dec 28, 2008 at 2:25 AM, bernie arai <bernie.arai(a)gmail.com> wrote: -- ./MiS 514-344-0726 http://www.creazone.ca
