Solaris and undefined symbol inet_pton

[Jeffrey Walton]

Hi Everyone,

Continuing on the Solaris 11.4 i86pc build of OpenSSH. I added ac_cv_func_inet_pton=yes and ac_cv_func_inet_ntop=yes to configure and we got past the compile problem. Also see GH #153.

Now there is a small link issue:

The functions are part of libnsl on Solaris. LDNS should include these libraries in this exact order: -lresolv -lsocket -lnsl. See man pages section 3: Library Interfaces and Headers, page 331.
