After upgrading to pecl-memcached-2.1.0, memcache support is broken. At startup, I get this message: PHP Startup: Unable to load dynamic library '/usr/lib64/php5.4/lib/extensions/no-debug-zts-20100525/memcached.so' - /usr/lib64/php5.4/lib/extensions/no-debug-zts-20100525/memcached.so: undefined symbol: memcached_server_micro_version in Unknown on line 0 This is because the libmemcached version in portage (1.0.4) is too old. The API fix is here : http://bazaar.launchpad.net/~tangent-org/libmemcached/trunk/revision/1032#libmemcached-1.0/server.h Quick fix: upgrade dev-libs/libmemcached to 1.0.10 (so please, bump it ! ;)), and raise the pecl-memcached dependancy to require this version at least. Thanks !
Hi, Any news here ? pecl-memcached-2.1.0 is still broken in tree due to the missing libmemcached-1.0.10 Bump is requested here: #431440 and here: #429542
Using 1.0.4 I get the following: hermes ~ # php -i | grep memcached memcached support => enabled libmemcached version => 1.0.4 memcached.compression_factor => 1.3 => 1.3 memcached.compression_threshold => 2000 => 2000 memcached.compression_type => fastlz => fastlz memcached.serializer => php => php memcached.sess_binary => 0 => 0 memcached.sess_lock_wait => 150000 => 150000 memcached.sess_locking => 1 => 1 memcached.sess_prefix => memc.sess.key. => memc.sess.key. Registered save handlers => files user memcached So it works fine with 1.0.4. The upstream changelog also says it requires only 1.0.x. The dep string in pecl-memcached was wrong though, so I created a revbump to fix that.
So how can be explained the undefined symbol message I get when starting php ??? which is solved by upgrading libmemcached... The libmemcached commit is pretty obvious... For the record, the emerge --info (this is a hardened system, may be it can make the linker behave differently, stricter ?): # emerge --info pecl-memcached Portage 2.2.0_alpha124

Currently, I make pecl-memcached-2.1.0 run with a libmemcached-1.0.10 in a local overlay. If I downgrade libmemcached to 1.0.4, it fails to start again: # php -i | grep memcached /etc/php/cli-php5.4/ext-active/memcached.ini memcached memcached support => enabled libmemcached version => 1.0.10 memcached.compression_factor => 1.3 => 1.3 memcached.compression_threshold => 2000 => 2000 memcached.compression_type => fastlz => fastlz memcached.serializer => php => php memcached.sess_binary => 0 => 0 memcached.sess_lock_wait => 150000 => 150000 memcached.sess_locking => 1 => 1 memcached.sess_prefix => memc.sess.key. => memc.sess.key. Registered save handlers => files user memcached
this is solved for me with the libmemcached bump to 1.0.11
