[zeromq-dev] What is the difference between libzmq.dll and libzmq.lib under windows?

[Pieter Hintjens]

Hi Seref,

First off, 22MB for a static lib seems wrong. That may be pulling in a
lot of debug info or something, but it should be more or less the same
size as the DLL.

Second, when you use the import library (basically it replaces each
exported method call by a shim to the DLL method), it's finding the
DLL on the path, otherwise the program would crash when it tries to
call any 0MQ function. If it works, that's because the DLL is on the
path..

Lastly, if Scala basically compiles to C, you should be able to work
either with DLLs or static libs, so long as you use the same build
model consistently. It gets messy if you mix static and dynamic.
