Problems installing the memcached gem?

Posts


Seeing something like this while compiling libmemcached or trying to install the memcached gem?

checking for style of include used by make... GNU
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: in `/opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems/memcached-1.0.2/ext/libmemcached-0.32':
configure: error: C compiler cannot create executables
See `config.log' for more details.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Turns out this error is quite misleading: what I was actually missing was the SASL development headers. This was all easily fixed with:

sudo aptitude install libsasl2-dev
sudo rm -rf /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems/memcached-1.0.2/ext/libmemcached-0.32
sudo gem install memcached

(Your path to the gem that failed to install properly could well be different, so double check in your error output from the failed install.)

  1. Thanks for this! I spent an hour and a half trying to fix it before coming across your post.
