Been getting these compute errors immediately on my smartphone: https://lhcathome.cern.ch/lhcathome/result.php?resultid=251147453 Any ideas?

You may check if this is also applicable to your android device.

Right, I checked the kernel version and it seems to be a 32-bit system. Thanks.

What you are seeing is this:

The current "android" executable is just a big statically linked linux executable, built on a linux machine.
The newer versions of android do not like this.

We put a filter in on the android version to stop this executable being sent to the newer versions of android, but it does not seem to work due to a bug in boinc itself, which I hope will be fixed at some point.
Perhaps Nils or Laurence can comment on that last bit since it is out of my hands :)


Eventually I will make a real android executable if I get the time - the annoying part is making a fortran compiler that will work with the android libraries.
