Support for FreeBSD capsicum doesn't work on FreeBSD 10.1, due to cap_rights_init which returns a struct, instead of an int.
Did its return value change in FreeBSD 10? (Presumably it didn't change between 10 and 10.1.)
I think that we should follow OpenSSH and not test cap_rights_init.
If there are no systems that offer Capsicum but that don't have cap_rights_init(), there's no need to check for it. The comment there is # # Check whether various functions are available. If any are, set # ac_lbl_capsicum_function_seen to yes; if any are not, set # ac_lbl_capsicum_function_not_seen to yes. # # All of them must be available in order to enable capsicum sandboxing. # but, if there aren't any systems that have some but not all, testing for all of them is overkill. However, AC_CHECK_FUNCS is intended not to care what type a function returns - unless a header is included that declares a function, it gets declared within the test program as returning char, so the compiler shouldn't choke on returning its value from main(). Is this failing due to the *linker* rejecting it because of mismatched function signatures? _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
