I'll... Wait, that makes perfect sense. The machine that it worked on had 32-bit libs installed before I ever tried running boinc; the ones I have tried it on since then haven't.

Hey, it's working -- looks like it was the 32-bit libraries. The WGC apps are still i686, of course, which leaves us with the question of what exactly about the 64-bit version is 64-bit.
Thanks a lot. 7.10 is a really shiny release, and now everything is working perfectly. Sure makes my day. |

Glad I could help.
However, it looks like you downloaded the wrong file. http://boincdl.ssl.berkeley.edu/dl/boinc_5.10.21_x86_64-pc-linux-gnu.sh gives: boinc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux 2.6.0, dynamically linked (uses shared libs), stripped |

I might have run the command on a 32-bit copy or my old boinc executable by mistake. You're right, the one which is working does identify as 64-bit.
----------------------------------------EDIT: But I am very confident that it, the 64-bit version, was not working previously. [Edit 1 times, last edit by Former Member at Oct 22, 2007 3:21:43 AM] |

If you set the owner to 500 and that isn't actually your UID then it will definitely fail to execute. The group also isn't correct and, unless you're really logged on as a user named 'user', the user name could be wrong too. Do note that this is all garbage. Ignore it. |

But how so?

Bryn: My user isn't 'user', but since the root account is disabled I figured it would be counterproductive to give away my user name randomly. Your Linux user name, if posted to a public forum, is completely useless to anyone viewing it but the point is, if you start changing the ownership of files to assorted non-existent names you'll only be cooking up a heap of problems for yourself. Just repeat what you've done except use your actual user name instead of 'myuser', or 'user' etc. Remember that for Ubuntu, the user name is used for both UID and GID. Did you actually disable the root account yourself? Possibly not a Good Thing unless you've made other arrangements to become root. Ubuntu 'kind-of' forces the use of sudo for root-related activity which is no bad thing - other distributions just leave the root account set up as er, the root user with the root password requested during installation.

It's less useless if my user name on that forum is the address of the machine in question, which runs an ssh server, and if I haven't set up denyhosts or a firewall yet. Not that all of those factoids are actually true. I'm not sure why the UID/GID were 500; maybe it's a default of some sort.
What I did was copy the terminal output, put it into a text document, and replace my user name. I do disable the root account when using a distro that enables it by default; however, Ubuntu does not set up a root password by default. |

But how so? Why would it? So long as the file is executable to the user running it, its ownership is utterly irrelevant. (This should be self-evident: If ownership were required to execute a file, only root could run any of the standard utilities!) All of my boinc programs are still owner/group 500/500 because I haven't bothered to change them. |
