Message 20861 - Posted: 17 Oct 2008, 19:01:02 UTC

I'm brand new to linux and am still getting my head around the command-line style interface (thought my DOS days were over, heh.)

I've got boinc up and running, however I don't see any options for adding boinc to the list of screensaver options, nor does anything happen when I click the "show graphics" icon from the boinc manager.

Any suggestions?

Which Linux distro?
Which BOINC version?
What kind of video card do you have?
Which project is this for?
Do you have OpenGL drivers loaded for your video card?

The screensaver does not yet work in Linux. You can view the graphics, if the application has graphics, with the "Show Graphics" button in the Manager. But no screensaver yet. Sorry.

Adding, How did you install BOINC? From the repositories or using what Berkeley proivides?

OK, I appear to be running the BOINC client and BOINC Manager in Ubuntu, but all my tasks say "computation error". I'm assuming that, being a noob to Ubuntu, I've screwed something up in setting up, though I see nothing to indicate where to look. Sorry to be vague, but I'm pretty much lost in space on this one.

Can you give us a link to one of the errored results. It's hard to determine what's going on without that information.

Well, I'm not sure what you mean by a link, but I'll give you what info I have:

Project: QMC@Home

Application: QMC@Home preRC1 5.01 [followed by a huge shifting string of odd graphic characters]

Name: four_peptidsm-ecp2.15207_2

Does that help?

edit: OOPS, mystery deepens. It runs ABC@Home just fine. OK, so it only relayes to QMC?

Go to your account at the project with problems, computers under this account, the computer in question with the problem, tasks, copy the link to one of the tasks with the problem and post it here.

Here's a Task ID with Work Unit ID:

Task ID: http://qah.uni-muenster.de/result.php?resultid=7408100

Does _that_ help?

Yes it does, although I must say I have never seen the error 127 before. ;-)
The BOINC version that you are using, did you download and install it from Berkeley or through your package manager? If from Berkeley, could you please install the recommended version 6.2.15 (from here).

I'm running 6.2.1.2, and I honestly cannot remember where I got it. I've d/l'ed 6.2.1.5, and will install it.

---
edit: Oh wait. I've got an even dumber question. Now that I've downloaded the 6.2.15 version, I can't figure out how to install it. I admit I've been corrupted by Windoze, but dang! This should be simple. Please help a PC!

Did you note, though that I'm running ABC@Home just fine? The problem appears at this point to be local to QMC, though I've only got two data points.

Yes, it is a system problem, and no, I cannot understand how to fix it. I do not know my way around Ubuntu (Linux) yet. I can't even figure out how to install the recommended (sh) version.

4 digits on the version number... must be installed from the package manager. Berkeley releases always have 3 digits.

There's one user on the QMC forums reporting issues with Ubuntu.

My suggestion is to post over there. If you don't hear from Martin or one of the other admins in a few days, I'll drop them an email.

I don't understand. I don't crunch QMC. I don't even read their forums. Do you mean you've gone to the QMC forums and have discovered other Linux users are having troubles, that there is a fix but you don't know how to do the fix? In that case you'll have to help me out a little by providing a link to the QMC forum where the problem and the fix is discussed. Sorry, I don't have time to hunt around for it.

There is a fix, but the cause is unknown, and the "fix" is a workaround that uses techniques that are far too advanced for my meager Unix skills.

Or do you mean there is a problem with QMC's system? If that is the case then just set QMC to No New Tasks and wait for them to fix their problem.

And that's exactly what I did. :-)

Try these install instructions. Maybe bookmark that page.

I've been there. I need to learn more before I can exerccise that option. Geez, I used to be the king of the (DOD) command line. :-(

BTW, your Ubuntu... is it the 64 bit version or the 32 bit version?

32

The 4 digits is a typo. His task details, for example this one show the version as 6.2.12. Ubuntu repos could be sending version 6.2.12 though.

Also, and I should have noticed this earlier, his task details show

Amolqc-preRC1-501: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory


So, CycloneRanger, that's your problem, you're missing a shared library named libstdc++.so.5 or else it's in a directory that's not on the search path.



Yep, sorry, it's 6.2.12 running with 6.2.15 downloaded but not yet installed. (Don't know how ... working.)

So I'm missing a shared library? Wonder why? It must be related to QMC, not to other projects, I guess.

A shared library is like a DLL in Windows.

Why are you missing it? Well, the standard answer is that you've never asked Ubuntu's package manager to install anything that needs that library. If you had then Ubuntu would have installed it for you. However, so many applications need that library, I am surprised you don't have it already. In fact, I rather suspect you do have it and the QMC app is falsely reporting that it's missing. So let's do another check to see if you have it or not and then decide what to do from there. Open a terminal and enter the following command:

 whereis libstdc++.so.5


Then post here and include the response from that command in your post, please.



administrator@ubuntu:~$ whereis libstdc++.so.5
libstdc++.so: /usr/lib/libstdc++.so.6

cp /usr/lib/libstdc++.so.5 /usr/lib/libstdc++.so.6 will make the copy.

I think that should be
cp /usr/lib/libstdc++.so.6 /usr/lib/libstdc++.so.5
(if I recall correctly) since the .6 version is the source.
