Can't find libzmq.so under RHEL about ffi-rzmq HOT 5 CLOSED

The next version (master in github) will allow you to copy the library to /path/to/ffi-rzmq/ext which is the first place it will look for the library.

I will also add /usr/lib64 to the search paths. I wish this was standardized...

We installed the zmq library via a Redhat gem which installed it as /usr/lib64/libzmq.so.1. It looks like the libzmq.rb file doesn't find it in this directory. Could you add an override so that the path could be specified via a config/initializer or maybe add /usr/lib64 and /usr/lib to the search paths (although I think the .1 suffix will still confuse it).

Our workaround was to ln -s /usr/lib64/libzmq.so.1 /usr/local/lib/libzmq.so

Thanks! Will it still find it in lib64 if it's named with the .1 extension?

I don't know. Try cloning the github repository (where I've already added that path) and run 'rake spec' from that top directory. Let me know if it works.

I think that the FFI library knows to look at any *.so regardless of additional suffixes, but I am not certain.

It didn't find the file with .1 extension. It does work if I do "ln -s
libzmq.so.1 libzmq.so" in the /usr/lib64 directory.

This issue should really be resolved by the FFI support in the various Ruby runtimes (MRI, JRuby, Rubinius). Finding the correct library is FFIs job especially when all of the paths are correct.
