compile error in memcached gem

[jboutelle]

Greetings Even,

We are looking to use the memcached ruby gem that you wrote to help with performance. We encountered this compilation bug when we attempted to install the gem.

Thoughts / ideas?

Actions taken:

1. clean EC2 instance US-West: ami-e32273a6 (CentOS 5.4) m1.small (32 bit)
2. compiled and installed: libevent-1.4.13-stable
3. compiled and installed: memcached-1.4.5
4. created /etc/ld.so.conf.d/memcached.conf 1 line of content: /usr/local/lib
5. gem install memcached

Skipping a lot of compiling information; this was the error we received:

Not sure but you may need a SASL2 development package installed on Centos.

fauna's suggestion worked for me on vagrant/ubuntu:

sudo apt-get install libsasl2-dev

[asoules]

libsasl2-dev fixed this problem for me, on Ubuntu 9.10.

[darscan]

Seems that libsasl2 is called cyrus-sasl on Centos, but even after installing cyrus-sasl and cyrus-sasl-devel I couldn't get the gem to install. Has anyone managed to get this running on Centos?

[chirantan]

I already have libsasl2-dev installed but I still got this issue on Ubuntu 10.04 - the Lucid Lynx. This was because I already had a partial (failed) gem installation in my gems directory. I did an rm -rf on the directory and has tried re-installing the gem. This time it worked.

[ajeje]

I had the same problem on Ubuntu 11.04. Installing libsasl2-dev fixed the problem for me.

[lanrion]

me too.

[padcom]

Works with Ubuntu 12.04 too

[egonSchiele]

extconf didn't notify me about sasl, but installing cyrus-sasl and cyrus-sasl-devel on CentOS v 6.3 worked for me.
