Hi
There are several reports (not only for Fluka) that on the latest Mac OS
versions, due to a problem in Xcode, the is a BUS error running code
with weak linker symbol.
Do you have any other message related to the error, for example
something like:
"Program received signal SIGBUS: Access to an undefined portion of a
memory object"
If so, please try relinking using the script in attachment (rename it
lfluka and substitute to the one in $FLUPRO/flutil before linking the
Fluka executable again*). It should fix (temporarily) the issue by
invoking the old linker. In case this is indeed the problem, I
understand there is a newer version of Xcode on the Apple developer site
which fixes the issue. Invoking the old linker is an option deprecated
by Apple and it will not work forever, however it is worth a try since
it will put you back in operation immediately and it is much simpler
than upgrading Xcode.
* $FLUPRO/fluka -m fluka -o flukahp
Please let us know if indeed this is your issue, and if so, if the
enclosed script works.
Ciao
Alfredo
