PHP :: Bug #30995 :: Net-SNMP5.2 causes compile failure in ext/snmp/snmp.c

 [2004-12-06 10:53 UTC] robbat2 at gentoo dot org

Description:
------------
(Apologies if this is a dupe, my ISP is having some issues tonight)
PHP4* and PHP5* (including the latest releases AND CVS checkouts) do NOT compile on a system with Net-SNMP 5.2*.
This is because Net-SNMP has become more standards-compliant and got rid of some AES192/AES256 stuff they had.
To conform with RFC3826, these are the changes they made:
http://cvs.sourceforge.net/viewcvs.py/net-snmp/net-snmp/snmplib/snmpusm.c?r1=5.10&r2=5.11&only_with_tag=MAIN
http://cvs.sourceforge.net/viewcvs.py/net-snmp/net-snmp/snmplib/snmpv3.c?r1=5.9&r2=5.10&only_with_tag=MAIN
http://www.ietf.org/rfc/rfc3826.txt
Note the removal of the following symbols:
usmAES192PrivProtocol
usmAES256PrivProtocol
PHP uses the above 2 symbols.
I've got a patch for ext/snmp/snmp.c to make PHP compile properly for all versions of net-snmp now.
Patch for PHP4:
http://dev.gentoo.org/~robbat2/php4-netsnmp52-aes.diff
Patch for PHP5:
http://dev.gentoo.org/~robbat2/php5-netsnmp52-aes.diff
Reproduce code:
---------------
Install NET-SNMP-5.2*
configure with SNMP turned on
try to build.
Expected result:
----------------
should compile fine.
Actual result:
--------------
