[zeromq-dev] Not a valid DLL error

[Eric Hill]

Here is how Windows searches for a DLL:

http://msdn.microsoft.com/en-us/library/7d83bc18(v=vs.80).aspx

References are for ActiveX or .Net frameworks, which libzmq.dll is not.
 What language is your application written in?  C?  C++?  For C
applications, the linker links to libzmq.lib, which contains a definition
of the libzmq.dll export table.  The idea is that once an exe is linked,
Windows will take care of loading the libzmq.dll into the app for you.  If
Windows can't find it, then you get the error you're seeing.

Since you said you put it in the bin/debug folder, I assume you're building
a release build and now your exe is in bin/release?  Did you put the
libzmq.dll in that folder?
