Configuring SASL support in libmemcached

Question

I'm trying to build libmemcached with SASL support on OS X Mountain Lion.

I have built memcached (1.4.15) with SASL support:

 $ memcached -S -vv
 Initialized SASL.
 slab class 1: chunk size 96 perslab 10922
 ...
 slab class 42: chunk size 1048576 perslab 1
 <17 server listening (binary)
 <18 server listening (binary)
 <19 send buffer was 9216, now 3728270
 <20 send buffer was 9216, now 3728270
 <19 server listening (udp)
 <20 server listening (udp)
 ...

I am trying to build libmemcached with SASL support too. I have tried the following:

 $ ./configure --prefix=/usr/local \
 --with-memcached-sasl=/usr/local/bin/memcached
 ...
 $ ./configure --prefix=/usr/local \
 --with-memcached-sasl="/usr/local/bin/memcached -S"
 ...

But the resulting configuration summary is the same for both:

Am I doing something incorrectly? Thanks.

• John Keyes: It works when I set ac_enable_sasl=1. Is this a variable that is supposed to be set by autoconf? It seems like a cheat to me.
• John Keyes: My mistake, pylibmc still raises TypeError: libmemcached does not support SASL.

Answer 1

This is not possible on OS X Mountain Lion (and possibly other versions of OS X). I'm going to raise the issue with the libmemcached team.
