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:

       * Debug enabled:             no

Am I doing something incorrectly? Thanks.

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, Sep 24 '12 at 23:25
My mistake, `pylibmc` still raises `TypeError: libmemcached does not support SASL`. — John Keyes, Sep 24 '12 at 23:32
Why? My second comment was to clarify that my first comment was incorrect. — John Keyes, Oct 08 '12 at 12:42

OK so here is a way, it's obviously not the 'correct' way but SASL support in libmemcached seems somewhat bitrotted.

Download libmemcached-1.0.8 (1.0.9 and later require code modifications sadly as SASL support hasn't been kept up-to-date with changes in the code).
Untar, change to folder.
sed -i -e s/ax_cv_sasl/ac_enable_sasl/ m4/ax_sasl.m4
sed -i -e "s/-pthread -pthreads/-lpthread -lpthreads/" m4/ax_pthread.m4
./configure
make
sudo make install

This should get it up and running on OSX (you need to do the same on Linux, or at least I did with Ubuntu).

Hi David, I tried this and the results of the configure (http://codepad.org/SN414faT) still do not indicate SASL support. Is that true or just a reporting bug? – John Keyes Oct 08 '12 at 09:04
I've followed the steps and it does appear that SASL support was compiled (http://codepad.org/MSIV76ir) but after following these steps (http://trondn.blogspot.fr/2010/02/memcached-with-sasl-on-opensolaris.html) it appears that the build was unsuccessful (http://codepad.org/haQ6AB6Z). – John Keyes Oct 08 '12 at 22:29
Hey John, one thing I had wrong was I recommended libmemcached 1.0.9. I should have said 1.0.8. The later version requires a small change to the code, it's an easy one but I'd say just use 1.0.8 as the above instructions work fine for it. – David Terei Nov 08 '12 at 20:40

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.
