Correct! IronPython 2.6.2 will work ALMOST correctly on Ubuntu 10.10, IF you use the binary which is linked for .NET 2.0. The error I experienced is that the black typeface on the default Gnome Terminal (with a white background) turns to light grey when IPy starts. If you switch Gnome Terminal to the black background, all is well. I assume that change happened after 2.6.b2. The version of mono is a more interesting story. (Bear with me, I spent a lot of time last week learning this.) Ubuntu has made the corporate decision to go with mono as part of their core. Ubuntu will not work without mono, and about 40 supported applications (they tell me) use mono. This is great news for the mono people, IMHO. But it comes with a cost. Mono is created on a Redhat-like system, SUSE. This is easy to understand, since the core group lives at Novell, the sponsor of SUSE. It seems that Redhat/SUSE have diverged enough from Debian that a significant amount of patching is required to make the stock (SUSE) release of mono work correctly on Debian. [An explanation for Windows users still following along: Ubuntu is a derivative of Debian, and uses most of the some packages. It has a MUCH faster release cycle, which I why I, and many others, use and prefer it. I attended my first meeting of the Utah Python Users Group last week and took a quick informal survey of the laptops present. Ubuntu:20.5, OS/X:2, other Linux:0, Windows:0.5. This in a place where lots of people work or worked for Novell, and the general population of programmers is heavily invested in Microsoft. The .5 is my (dual boot) laptop.] The Debian maintainers apply their patches to the LTS [long term support] version of mono, which at this point is 2.6.3. One of the Debian mono maintainers has supplied a patched 2.10 mono as a PPA on launchpad, but he only supports LTS versions of Ubuntu, which 10.10 is not. Therefore, the newest (i.e. .NET 4) software will not run on the newest Ubuntu. A very frustrating paradox. I received several suggestions about how to get around this problem, most of them involving virtual machines, or sandboxes. Since Redhat and SUSE are not as heavily invested in mono, they run more current versions. The latest suggestion, which I must rebuild my Linux partition before I can test, is this: v v v v v v v from Christopher James Halse Rogers <r...@ubuntu.com> sender-time Sent at 7:24 PM (GMT+11:00).
