Hi,
crypt(3) does not need -lcrypt on macOS, but need -lcrypt on Linux.
How does autotools determine what library is need to be linked based
on the source code? Thanks.
This is really an Autoconf (configure script) issue and not an
Automake issue. The common approach using Autoconf is to test various
known permutations (starting with nothing, and then adding crypt)
until linking succeeds.
I expect that there is already a macro from the Autoconf macro archive
which handles this case.
