I've been working on building a Ptolemy release that supports Itcl3.0/Tcl8.0.4/Tk8.0.5, and I keep thinking I'm almost done, but then run into further problems. At this point, I have a set of tar files that work reasonably well under Solaris2.5.1. The biggest problem is that parts of Tycho are not as well polished as they should be. In particular, the keyboard menu traversals do not work as well as they should. I'm also hoping that the next release will work better under Cygwin32. There have been a number of problems with that port. The current big problem is that the SDF Tk demos hang. The reason is that in Ptolemy 0.7.1, the Cygwin port did not use itimers and the event loop speedups. In the current sources we are using the event loop, which results in a 10x speed up. My guess is that this is the problem. Another problem that I'm running into is that when I untar the distribution using Cygwin tar I don't own the files, the administrator user owns them. As a result, I have to run chmod -R a+w $PTOLEMY. The Cygwin port required that some non-MSDOS compliant filenames be changed. In $PTOLEMY/lib/colors, there were directories with '%' in the name and a directory named 'con'. I renamed these directories and modified ptfixtree so that it automatically fixes the Ptolemy tree facets. Since the Itcl changes and the Cygwin file name changes are not backward compatible, we decided to call the next release 0.7.2devel The changes between 0.7.1 and 0.7.2devel do not include very many new stars or increased functionality, the changes are mainly there to cover ports. I'm willing to make the 0.7.2devel sources available on a limited basis, but they are not ready for public consumption yet. If you (or anyone else) wants access to the new tree, send me email, and I'll tell you how to download them. I think that having a few more people hack on the 0.7.2devel tree will help us figure out the bugs and get this released. BTW - Tcl Blend starts up from within pigiRpc. However, we have had various problems with pigi hanging, so it is likely that there are problems. You can download Tcl Blend 1.1 sources from http://ptolemy.eecs.berkeley.edu/~cxh/java/tcljava/ -Christopher -------- Hi Hackers, I have a lot of work devoloped in Ptolemy 0.7 (rebuilt from scratch on a SUN Solaris 2.6 platform) and I am tring to create some Tcl "gluing" scripts to interface all this stuff with other environments. For example, I ran into Tcl Blend which allows to easily interface Tcl with Java objects. However such package is available for Tcl8.0 whereas Ptolemy 0.7 uses ITcl based on Tcl7.6. ITcl has already the "class" definition needed by Tcl Blend, but may be there are other improvements in Tcl8.0 which are not present in ITcl. Could anybody give me more information on such problems? Do you know if and, in case positive, how it is possible to update the ITcl in Ptolemy 0.7 to Tcl8.0 including new Tcl extensions developed by myself or others (such as Tcl Blend)? Thank you.
