It looks like commit 7ff204c83595cd7d6b7b6a813d9fda97afd25198 introduced an error on some systems such as FreeBSD, whose grep doesn't support -P.

num() {
   echo "$1" | grep -P -q "^[0-9]+$"
}

./configure now reports:

grep: The -P option is not supported
seed_buckets                  4

Is -P required?


Hello Bex,

Does it work for you to replace -P with -E?

Alternatively, what if we replaced grep with

test "$1" -eq "$1" 2>/dev/null


Replacing it with -E works.
