Can't get work on linux systems. I have a systems I run under windows and linux. Under windows the systems get work but when booted under linux they download a single WU. Here's one of them...http://www.enigmaathome.net/show_host_detail.php?hostid=180360
Project resource share is 8000. Only other project attached is WUProp Any ideas?

Also, it's a server install of ubuntu 14.04 running boinc-client version 7.2.42

Geez, I need typing lessons.

I can't get any work on any linux system. I have a systems I run under windows and linux. Under windows the systems get work, but when booted under linux they won't download a single WU. I have 5 linux VMs and 3 native installs. None of them will download any work. I've uninstalled the Boinc-client and reinstalled on several systems and still no luck. They're runnng ubuntu 14.04 server install with boinc 7.2.42. They download and crunch every other project just fine. I've even detached all other projects so just enigma remained. Nada. Any ideas?

scole, did you know Enigma won't run on ubuntu server? Must be a desktop install for some reason. Hope this helps.

Son of a b....you're correct. Installed a desktop install and viola. Thanks scole.

Strange, from this page I would not conclude that the server edition behaves other than the desktop in this respect. Must be that you did not include 32-bits libraries in your server install, or something like that.

I posted this to an older stickied thread, just in case anyone didn't see it:

Hi,

I use 64-bit Slackware on one of my computers, which "out of the box" isn't backwards compatible with 32-bit binaries (or binaries supporting both). I have no interest in making it compatible, but would love to get Enigma@home on it.

Does anyone know where I can get the source code to compile this 64-bit version (the binary must not link to any 32-bit library)? Also, to install it, is it just a matter of ignoring BOINC's "not for your system" error, quit, and just drop the binary in the Projects subdirectory?

Thank you!

As far as I have understood, you need to download the application source and compile the 64-bit executable yourself. I hope the project will compile a 64-bit app themselves.

I recently packaged a ready to built source, it is available at https://github.com/whs/enigmathome. The release page also have prebuilt binaries for multiple -march and OS.

I haven't test this yet, the project server refused to give me any works (could be because of the server, or my app_info.xml) so please give feedback if you do get any work with this on.

I cannot use this, here is why:

(TLDR: BOINC deletes the files enigma and wrapper on each start, and I cannot compile as I'm stuck with CMAKE v2.8)

The last stable version of vanilla Slackware (v14.1) was released in 2013, and installing the "slackware-current" rolling release would involve a major and possibly destructive overhaul. "Slackware-current" v14.2 is currently in its second beta version.

I was unable to compile the source, since the CMAKE version requires version 3, which is present in v14.2 Beta, while Slackware v14.1 uses 2.8. For this reason I could not generate a Makefile. I tried installing CMAKE from v14.2 Beta, but it requires newer libstdc++ which would surely cause chaos if I upgraded that.

So I attempted to use the binaries for Sandy Bridge (I have a Haswell Refresh i7-4790k), and put the four files into the projects folder. That didn't work because BOINC deletes "enigma" and "wrapper" on each start! The log gives a vague message about job.xml not being present, when it is present in that same folder.

Could you try removing

<file_ref>
<file_name>job.xml</file_name>
</file_ref>


from app_info.xml?

I could replicate this problem on my end as well, but I could not force BOINC to get more work so testing this is really hard.

Edit: I think that solves the problem. However, a new problem emerges. It seems that the job.xml I got from other optimized app could be out of date and the parameters to enigma executable are incorrect. I'll look into that.

That keeps the precompiled Sandy Bridge app in the folder, but every downloaded WU fails with "Computation error".

BTW I upgraded to slackware-current, since v14.2 is almost ready and they're taking backorders for DVD-ROMs. So if there's a need to compile from source I can do that. My CPU is Haswell Reloaded/Devil's Canyon which four steps higher than Sandy Bridge.

Should probably mention that I finally got tired with Slackware's two years of teasing and installed LinuxMint 17.3 XFCE. When using third-party repositories that are more up-to-date, I've found it to have the benefits I enjoy with Slackware without the inconveniences that Slackware has. A repository of up-to-date NVIDIA proprietary drivers allows me to use GPU-based SETI@Home, and being multilib compatible Enigma@Home works too.

So now I have a Windows and a Linux computer, both having the same i7-4790k CPU, GTX 960 GPU, and 32 GB RAM, and both working on the same projects, which doubles my contribution to BOINC including Enigma@Home.
