FahCore_a7 0.0.17 fails to start on Ubuntu 14.04 LTS

Either because of version 0.0.17 or the core URL switch, this machine has been trashing a7 work units until it is assigned an a4 work unit. It's an original Core 2 Duo without AVX and uses the SSE version of the core.

Last successful a7 with 0.0.16 from fahwebx.stanford.edu:

Is it possible the AVX version of the core was placed in the file location where the SSE version should be? Were there compiler or dependency changes between 0.0.16 and 0.0.17?

The only dependencies I'm aware of are minimum versions of glibc (2.17) and glibc++ (3.4.15).

If you navigate using Nautilus or Files to the sub directory containing FahCore_a7 and open a terminal there (right click - Open in Terminal - assuming you have nautilus-open-terminal installed ... otherwise you might have to navigate there using Terminal and the cd command) ... then you can type:

Code: Select all

ldd FahCore_a7
to see if any dependency errors exist.

If your versions are too old you may be able to install newer ones by downloading the needed deb file.

Yes, it's possible. How did you download/install FAHCore_a7?
-----------------
Similar to what "bollix47" said (but not the same) navigate using Nautilus or Files to the sub directory containing FahCore_a7 (it's actually /var/lib/fahclient/cores/cores.foldingathome.org/Linux/AMD64/Core_a7.fah) and open a terminal there (right click - Open in Terminal - assuming you have nautilus-open-terminal installed ... otherwise you might have to navigate there using Terminal and the cd command) ... then you can type:

Code: Select all

./FahCore_a7
to execute that program. It will print useful information to the terminal, including a line that either reads SMID:sse2 or SMID: (something else).

The core was automatically downloaded by FAHclient as indicated in the second log snippet.

Manually starting FahCore_a7 produces the same two dependency missing lines as above.

Edit: This looks similar.

Have you installed the updates for 14.04 (v3.13)? Those pre-reqs may be included as part of the Long Term Support process.

Have you installed the updates for 14.04 (v3.13) or even to 14.04.5? Those pre-reqs may be included as part of Ubuntu's Long Term Support process.

(I've had problems finding CXXABI/GLIBCXX in the past and I don't remember what update I installed that fixed them.)

Yes, Ubuntu version is 14.04.5 LTS and kernel is currently 3.13.0-149.

In the issue I linked to, jcoffland mentioned compiling with one version older to keep FAHClient compatible with 14.04.5 LTS.

To me it looks FahCore_a7 0.0.17 was built with a newer compiler. In my first log snippet, you can see 0.0.16 mentions "Compiler: GNU 4.9.2". Since it doesn't start now, I can't see the current Compiler version. It's possible that the same compiler was used but a code change or bugfix used a feature not present in CXXABI_1.3.7.

Is there an accurate list of supported Linux distros? The Linux system requirements looks outdated since it mentions Ubuntu 11.04.

In case it's useful, here's some strings output.

Newer compilers are potentially the problem. Newer compilers generally come with newer versions of the libraries, but there's a pretty good chance that you CAN upgrade the library on your version of Ubuntu without causing any difficulties.

The entry CXXABI_1.3.9 is required by GROMACS (which is used in FAHCore_a7), so you need upgrade your library to a version that contains that entry. I may have upgraded my library or I may have installed it separately -- I don't remember.

This issue was closed in an earlier version of FAHClient but apparently has come back.

Open a terminal & try the following:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test 
sudo apt-get update
sudo apt-get upgrade
Restart the folding client.

I just hacked on my old Ubuntu 12.04 install to get it working with A7 V17 (V16 worked fine). Updating the C++ libs and gcc to the Trusty/Xenial versions did the trick.

Or the distribution ... those library issues are the reasons why I upgraded my old server to 16.04 ...
