Re: [Wlug] AMD64 and 32-bit apps

I'm currently running Gentoo for AMD64 on a dual Opteron system. Everything works fine, and I'm really happy with it. I have been able to run binaries compiled on 32-bit x86 systems without any problems so far. It sounds like you need to do some cross-compiling for 32-bit x86. I've never done that, so I can't say how well that would work, but if you have the "cross" and "multilib" USE flags, you should have all of the components you need to do that. I have also run 32-bit Slackware on the Opteron box, and that worked fine. So if you don't want to deal with the AMD64 and cross-compiling issues, you could just install a 32-bit Linux distro on it with no performance hit. Keep in mind that there aren't anywhere near as many Gentoo packages in Portage that are marked stable for AMD64 as there are for x86, so that may be a problem for you if you can't live without some specific package. There are other possible issues if you intend to use your AMD64 box as a desktop system. For example, Flash doesn't seem to work on AMD64 yet, and I don't think you can play WMV files, even with the 32-bit libraries. If you want to know more about my specific experiences with AMD64 on Linux, feel free to contact me or drop by the Sin Lab. -James > Recently I've begun considering migrating over to the amd64 platform (my > motherboard just died on my athlon xp system, much to my chagrin) and > figure this is a good place to ask for users experiences.

AMD64 and 32-bit apps

by Carlton C. Stedman II

Recently I've begun considering migrating over to the amd64 platform (my motherboard just died on my athlon xp system, much to my chagrin) and figure this is a good place to ask for users experiences. I'm not worried about my video card drivers, since NVIDIA has great amd64 support, at least, so I'm told. My main concern is that I need to install some 32-bit emulation libraries and kernel modules, so I've read, to compile 32-bit apps, and that some compiled 32-bit apps will only work under a 32-bit environment, requiring me to setup a seperate environment to chroot into. I'm running gentoo and I'm up to the task, just wondering if anyone has any experience in this specifically and anything I should be concerned about or not to worry too much about.

gnome-terminal/mutt question & solution

by Bill Mills-Curran

Ok, this is going to read more like a detective novel... :-) I'm using mutt in a gnome-terminal on fedora core 3, and I'm up to date (within a week) with updates. I find that, with the defaults, the terminal does not refresh when it needs to. A ctrl-L repaints the window just fine. I did (just now!) find a fix... Right clicking on the terminal -> Input methods and select "X input method"... Everything works fine, except this setting is not persistent. The setting affects all gnome terminals and new ones opened. However, if I first close all terminals and start a new one, the setting is lost. So, how to make the fix stick? I have no idea, but I did find this info on the subject: http://www.webservertalk.com/archive204-2004-9-379265.html This gives a link to a new terminfo file which you can use to fix the problem, and a nice way to install it without editing the distro-supplied file. Thus far it works fine. Bill

Re: [Wlug] fedora 1

by Lee Keyser-Allen

I just wanted to apologize for spamming the list (by spamming the list) with my attempt at humor ... I was just thinking about e-mail viruses, and I felt nostalgic about a time where e-mail viruses were a joke that could never happen because, quite simply (with exception of those people who used emacs) our mail reader was just a mail reader ... a method to display text on a text console. Some days I miss that. Other days, I just revel in gmail and get over it. So yeah, sorry 'bout that. I hope that at least three of you saw the humor ... 'cause then my ramblings weren't a complete waste of CPU cycles.

Re: [Wlug] fedora 1

by Lee Keyser-Allen

Are you talking about on the Windows side, or the Linux side?? The one virus that you should be concerned with on the Linux side is a particularly insideous virus called the "Good Times" virus. This has been around since the early 90s and can target any e-mail system. It continues its resurgence despite repeated efforts to put it down. You can find out more about it and how to protect against it at: http://ciac.llnl.gov/ciac/notes/Notes09.shtml or google Goodtimes virus. Consider this my public service for the year.
