The Berkeley EECS Ptolemy project has a 0.6 beta release. To answer the first question: "Ptolemy is a research project and software environment focused on design methodology for signal processing and communications systems. Its scope ranges from designing and simulating algorithms to synthesizing hardware and embedded software, parallelizing algorithms, and rapidly prototyping real-time systems. The work is conducted by the DSP Design Group of the Department of Electrical Engineering and Computer Sciences of the University of California at Berkeley. The project is directed by Prof. Edward Lee and Prof. David Messerschmitt. The project is named after the second century Greek astronomer, mathematician, and geographer." I got it working during the alpha period for FreeBSD but haven't had time to do a formal port of it. It should work out of the box once you get the bleeding edge development environment installed - see requirements below. Anyone using an earlier Ptolemy version will want to test this beta if they have the time. If there are any ambitious sound users "it would be nice" to test out the sound demos and get them working- you need a Sun compatable /dev/audio, which I believe we have. REQUIREMENTS: The pgcc port of 2.7.2 in ports; libg++-2.7.1 from prep; gmake 3.74 ports; pt-0.6beta.oct.src.tar.gz, pt-0.6beta.other.src.tar.gz, pt-0.6beta.src.tar.gz See http://ptolemy.berkeley.edu/pt0.6beta.html More than 64 MB swap to compile (I went to 96) The specific instructions for FreeBSD are in the distribution in ptolemy/mk/config-freebsd.mk. I also have a build script that I use if anyone needs it. -- Temporarily via "hdalog@zipnet.net"... Peter Dufault Real-Time Machine Control and Simulation HD Associates, Inc.
