Solaris pages apply to the Sun or Oracle operating systems. Generally speaking, Crypto++ attempts to support Solaris 9 and above. Solaris 10 and 11 should work out of the box.
Solaris 9 on i86pc may need
cryptopp.mapfile patched. Solaris 9's mapfile uses a different format than the current format used by Solaris 10 and 11.
