[zeromq-dev] Ruby language binding

[Jim Hodapp]

I'm trying to run zeromq on a Mac running OS X Lion. I have Xcode installed as which gives me a Ruby installation of version 1.8.7. I have downloaded the latest zeromq stable version, ran ./configure, make and make install. By default it installed to /usr/local. Now I am attempting to install the zeromq Ruby language binding but cannot get it to find my zeromq installation. I have tried several things, but the following 2 are the ones that should work but don't:

sudo gem install zmq

sudo gem install zmq -- --with-zmq-dir=/usr/local/lib


Both result in the following output:

Building native extensions.  This could take a while...
ERROR:  Error installing zmq:
	ERROR: Failed to build gem native extension.

        /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb --with-zmq-dir=/usr/local/lib

checking for zmq_init() in -lzmq... no
extconf.rb:36: Couldn't find zmq library. try setting --with-zmq-dir=<path> to tell me where it is. (RuntimeError)

This is what is contained in /usr/local/lib:

drwxr-xr-x  3 root  wheel      102 Jan  4 08:12 pkgconfig

Any thoughts would be appreciated. Is there a way of running the gem installation with a verbose output?

Thanks,

Jim
