It might also depend on encryption/password hashing options you chose when installing the OS. in my case (FreeBSD 4.2-Release using md5 password hashing), i found that php was using libcrypt.so. i also found that libcrypto.so had the functions listed above and libcrypt.so didn't. i didn't really want to mess with the configure script since i don't understand the syntax, after running the basic configure, i went and edited config_vars.mk. in EXTRA_LIBS i just added -lcrypto and when i next compiled it all worked.. the right library to use in your case may vary. actually, i still have problems. when PHP runs it whines that it can't find the MIB modules, e.g., ... Cannot find module (SNMP-MPD-MIB): At line 0 in (none) Cannot find module (SNMP-USER-BASED-SM-MIB): At line 0 in (none) Cannot find module (SNMP-NOTIFICATION-MIB): At line 0 in (none) Cannot find module (SNMP-TARGET-MIB): At line 0 in (none) Cannot find module (SNMPv2-TM): At line 0 in (none) that does no harm for me though (since i don't use those modules) so i haven't gotten around to fixing that. tiger.
