[aspect-devel] Floating Point Exception error for simple setup

Hi Felipe,
'cmake' is only a helper program that sets up a proper Makefile for
compiling aspect. To actually change your executable you will always
need to recompile aspect after changing things with cmake (see
https://cmake.org/overview/ for a more lengthy explanation). Try typing
'make' in your build folder
(/home1/04020/unfelipe/packages/ASPECT/build/) and start the model
again. This should help.
@Timo: I know the FP_Exceptions are very helpful in debugging, but it
seems the test for their availability is really fragile and breaks on
many clusters. This is basically not our fault, but I have the feeling
half of the crashes currently reported on github or the mailing list are
caused by them either being falsely activated by the build system, or
manually activated although they are not available on the system. Do you
think it would help to switch them off by default and hide their cmake
option behind an 'Advanced' switch? It would save us a lot of
meaningless crashes and mails ;-). I have started to simply disable them
manually on every new system, since I only need them on the ones that I
use for developing.
Best,
Rene
