I'm having a rediculously hard time trying to find a CentOS 3 installation disc image (or any other version before 5.6). This is the closest I've been able to find: http://mirrors.cmich.edu/centos/3.1/ But I don't see anything in any of those directories that looks remotely like a disc image. Even though the chart on this page seems to say that mirror should have them: http://www.centos.org/modules/tinycontent/index.php?id=30 On this page... http://isoredirect.centos.org/centos/4/isos/i386/ ...it *says* that that I can "download the .torrent files provided", but there's no torrent files listed there or at the mirrors, and the only other promising-looking link that page has is here: http://packages.sw.be/bittorrent/ Which, despite the url, doesn't even have any torrents at all, just a bunch of rpms. How's a torrent client supposed to use an rpm? I seem to remember having pretty much the same problem about a year ago when I blew a full day trying to get ahold of a copy of Debian. Eventually I gave up trying to find it and just went back to Ubuntu. I don't have a problem using VirtualBox for this if I need to (Assuming I can actually get ahold of an appropriate OS). I actually quite like VirtualBox; been using it a lot the past year, and I have plenty of disk space. But, if all I need to do is get my app to link againt an older version of libc, shouldn't there be a way to do that right there on my Kubuntu 10.04 system? I had been shying away from Alexander's suggestion of uClibc because uClibc's website says it sacrifices speed for size, and because it looks like a royal pain to get set up. But if I can't get this CentOS solution to work, I may give it a try anyway. Also, I've found on Google that the message I got ("linux.so.2: bad ELF interpreter: No such file or directory") is known to sometimes occur when running a 32-bit binary on a 64-bit system that doesn't have the 32-bit libs installed. In case that turns out to be my real problem and my webhosts are unwilling to install the 32-bit libs, can DMD still output 64-bit binaries when building on a 32-bit system? My guess would be "no" since linux seems enjoy crapping out when trying to compile for anything but the local system.
