Installing memcached 1.2.6 Edit

Created 2/28/2009, updated 3/12/2020

Installing on Mac OS X Leopard 10.5.6

First we install libevent, a prerequisite for installing memcached:

wget http://www.monkey.org/~provos/libevent-1.4.9-stable.tar.gz
tar xzvf libevent-1.4.9-stable.tar.gz
cd libevent-1.4.9-stable
./configure
make
make verify
sudo make install

Now moving on to memcached itself:

cd ..
wget http://www.danga.com/memcached/dist/memcached-1.2.6.tar.gz
tar xzvf memcached-1.2.6.tar.gz
cd memcached-1.2.6
./configure
make
make test
sudo make install

Installing on Red Hat Enterprise Linux 5.1

When I tried the same procedure on RHEL I found that memcached wasn’t able to find the libevent library at runtime.

This is because it gets installed by default in /usr/local/lib and that is not in the dynamic loadpath.

Troubleshooting options

# confirm "not found" for libevent
ldd -v ./memcached
# see where memcached is looking for the library
LD_DEBUG=libs ./memcached -vv

Workarounds

# export path before launching memcached
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
./memcached

Final solution

That run-time workaround strikes me as a bit ugly. I tried some other tricks at compile-time, but nothing worked.

In the end I decided that installing libevent into /usr/lib rather than /usr/local/lib was the least hideous alternative.

So the final installation incantation was:

wget http://www.monkey.org/~provos/libevent-1.4.9-stable.tar.gz
tar xzvf libevent-1.4.9-stable.tar.gz
cd libevent-1.4.9-stable
./configure --libdir=/usr/lib
make
make verify
sudo make install
cd ..
wget http://www.danga.com/memcached/dist/memcached-1.2.6.tar.gz
tar xzvf memcached-1.2.6.tar.gz
cd memcached-1.2.6
./configure
make
make test
sudo make install
