Message 1784 - Posted: 30 Oct 2005, 22:27:11 UTC

Please report any issues with the new linux client in this thread.

This client is the first new revision of the old linux client. It should support most of the BOINC functions that the windows client supports and should more or less be equal in appearance and behaviour.

It was compiled on Sourceforge\'s compile farm using a 2.6.x kernel under Fedora core 2. Due to the fact that Fedora core 2 is a relatively recent distribution there may or may not be library issues that need to be resolved.

Nope. Part of this test is to try out some of the new mirror software, this can be done by both Windows and Linux hosts. The focus of the results, however, will mainly be on finding problems in the linux client (because most Windows issues are already known).

I probably should have made this more clear in the newsposting - thanks for asking!

I just tried attaching a new machine (Dual Opteron 250 running 64bit Linux) to the project and it didn\'t like it much:
2005-10-31 08:49:54 [BURP] Starting result 139in0.zip__ses0000000139_frm0000000600_prt00000.wu_1 using blender version 4.20

This is with BOINC 4.43.

Looking at your result the error was \"blender_4.20_i686-pc-linux-gnu: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory\".

Could you try symlinking that to libstdc++.so or libstdc++.so.0 and see if it works? It should be in /usr/lib or something similar.

Bummer, I just spent last week installing that 32bit compatibility package on a bunch of other machines for a totally unrelated reason. I\'ll throw some RPM packages at it and see if that improves things...

Does your system contain anything that looks like libstdc++? It\'s a pretty common library I guess, but perhaps not common enough to dynamicly link against it...

I fixed the problem on my AMD64 system by installing the compat-libstdc++-33-3.2.3-47.3.i386 package and it\'s rendering happily now. I\'m running Scientific Linux 4 which is bascially the same as RHEL4. Given that Fedora is used as the basis for RHEL, I would think a similar solution would apply to Fedora also.

Hmm, spoke too soon... Some of the frames are working but I\'m getting a different error code now:
2005-10-31 16:09:33 [BURP] Starting result 139in0.zip__ses0000000139_frm0000001146_prt00000.wu_4 using blender version 4.20

Anything I can do to help track this one down ? (It\'s result id 83683)

Now that\'s pretty odd, it starts up fine but dies pretty quickly because of lack of communication from the core client (BOINC):
No heartbeat from core client for 31 sec - exiting
CCom: 0.049310 - 29.453000
Lost heartbeat, killing everything...
Exit requested by child or CC

Could you try updating your core client to version 5.x?

I upgraded to 5.2.5 and apart from some slightly odd temporary file upload problems which have gone away now, it seems to be working OK.

Thanks for the help! Compat-libstdc++-33-3.2.3-47.3.i386 package works greatly with Fedora! I was able to get libstdc++.so.5 for Ubuntu from here:

http://packages.ubuntu.com/hoary/base/libstdc++5.

Haven\'t seen any new problems yet.. :)

I get slightly different messages on the console:
2005-11-01 12:36:25 [BURP] Started upload of 139in0.zip__ses0000000139_frm0000002459_prt00000.wu_2_0

This may be a Linux specific thing... Speaking of Linux, I notice that v5.2.6 is out; does anyone have a link to a version history or a changelog which says what changed between the versions ? I\'ve had a poke round the main BOINC site but can\'t even find announcements of the new versions.

It\'s not linux specific; I\'ve had lots of these errors reported by my windows client during session 139 and it looks to me like a server issue. It can take an hour but so far all transfers affected by this on my PC have eventually gone through.
