Description Marius Schamschula 2021-11-08 18:16:59 MST

I have been made aware that there is an issue with

lib/util/arc4random.c and lib/util/arc4random_buf.c making use of the minimum() macro, but this macro is only defined in lib/util/arc4random.c (in line 59) and not in lib/util/arc4random_buf.c:

arc4random.c:59:#define minimum(a, b) ((a) < (b) ? (a) : (b))

Symptom:

sudo will configure (with a sprintf warning), build, install, and activate OK, but invocation of sudo then fails with:
dyld: Symbol not found: _minimum

Solution:

include the definition of the minimum() macro also in lib/util/arc4random_buf.c
