I actually have 1 unit that succeeded, but it was a noise unit (30+ spikes in under 2 minutes), all other 30-ish units failed with SIGSEGV. This is on BOINC 7.4.53 on Android 7.1.2 (LineageOS 14.1)

OK, that's what I meant. I assume it will pick up a new app when it's ready, like Einstein did?

So is it safe to run SETI on Android 5 (as in it won't unnecessarily ask for work) ?

Einstein runs fine indeed, I've set the other projects (including this one) to "no work" for now to prevent downloading unprocessable tasks.

I somewhat naively updated my Nexus 5 phone to Cyanogenmod 12 (which is based on Android 5.0.2) today... This resulted in BOINC still working (using the latest version) but the seti binaries fail to run because they are not Position Independent Executables. Are there any plans to support Android 5?

That´s great news, looking forward for some more SETI work!
7) Questions and Answers : Wish list : build without graphics (X11) (Message 875812)

I've made an update to the port (not committed yet) to make X11 optional and to update Astropulse to version 5.03 It can be fetched from [1]. It is also available as a patch to the current port version from [2]

The clients compile but if you don't select X11 with Astropulse, the Astropulse client will crash when starting up :( If anyone knows a *proper* fix (i.e. not adding graphics-only include files) for this, let me know.

I get these messages from time to time on my FreeBSD box, usually when the cpu is drowned in work (load > number of cores). The excessive load causes the BOINC manager to not pick up the "I'm alive" signal from the science processes, and consequently thinks they have terminated, so it restarts them. The excessive load can also cause the science processes to be asleep for more than 30 seconds, in which case they don't send the "I'm alive signal", but are still running.

I figured out that the problem is specific to astropulse, setiathome does respect the --disable-graphics option (and consequently builds a slightly smaller binary :) )

Post:
After I ported the setiathome 6.03 and astropulse 5.00 to FreeBSD I've got some requests if it would be possible to compile the clients without graphics support. This way it is possible to run the clients on headless stations without having to install X11.

There is a --disable-graphics knob in the configure scripts but currently it is broken, because (as far as I can see) the state information of the math part of the astropulse client is stored inside a graphics structure (why?). This used to work fine in the previous version of the setiathome client (5.27).

I might be able to come up with some patches myself (against SVN head). Is there any interest for this?

Today the FreeBSD port astro/boinc-setiathome-enhanced got updated. It installs setiathome 6.03 and astropulse 5.00 from source.


This would not have been possible without Dotsch' help. Thanks Dotsch!

I'm now using revision 333 of setiathome and revision 354 of astropulse.

The problem with that astropulse revision is that it effectively kills the --disable-graphics switch of configure, since the developers have made the IMO rather peculiar decision to put the current state into the graphics shared memory. I have some patches to make the switch useful again, but I guess I have to change the source code more than just adding some missing #ifdef BOINC_APP_GRAPHICS ... #endif tags to make it work.

The whole point of releasing setiathome 6 was that the science and graphics part are two separate pieces IIRC. Shouldn't astropulse do the same, for people who cannot or don't want to run the graphics part?

Google doesn't know the fold_buf_{long|short}_{pos|neg} functions either.


ap_client_main.cpp: In member function 'void Astropulse::Client::init()':
ap_client_main.cpp:708: error: 'fold_buf_long_pos' was not declared in this scope
ap_client_main.cpp:709: error: 'fold_buf_short_pos' was not declared in this scope
ap_client_main.cpp:712: error: 'fold_buf_long_neg' was not declared in this scope
ap_client_main.cpp:713: error: 'fold_buf_short_neg' was not declared in this scope
Most possible an undeclared variable, because of work in progress. You could always tell svn to download an older revision.


I know. Is there a list of svn revisions used as releases?

Substituting sh with bash helped, but now I get a compile error for astropulse.
This is probably an error in the source code. I'm using SVN for both astropulse and setiathome:

Am I right that SVN always contains the latest source code?

Strange, astrpoulse passed configure with sh on FreeBSD 7.0

But I will try bash.

Does anyone know what's going on?
