This is the implementation of Paolo Denti's and Justin DeWind's ZeroMQ Universal Framework for iOS devices.

I haven't done anything all that exciting; I followed directions and solved a discrepancy.
All kudos go to the above authors.
Compiled with: Xcode 5.0.2, for iOS 7.0 and ...
... submod:zeromq4-x release:v4.0.4
... submod:czmq2-x release:v2.0.3
Usage of the Framework is Paolo's Step 5, but I do have an errata!
- just create a normal ios project
- drag the
ZeroMQ-iOS.frameworkfolder in theFrameworksgroup (check the copy checkbox) - click on the project, build settings, add
-lstdc++to “Other Linker Flags” (the C++ standard library is needed by zeromq) - add the framework headers (just add
$(SRCROOT)/ZeroMQ-iOS.framework/Headers) to the “Header Search Path” compiler directive - just use normally zeromq in your application (the only note about is that you should
#include "zmq.h"instead of#include <zmq.h>)
Errata: The “C++ Standard Library” setting in the Xcode project determines the “Other Linker Flags” that you must include. If libc++ (LLVM C++ standard library with C++11 support is specified, then the flag must be -lc++ instead of -lstdc++.
From Justin's blog:
Because I don't save xcuserdata in git, Justin's step: “Configure aggregate target build against the ‘Release’ configuration” must be done for the user compiling the project.
Right-click on the lib Product and “Show in Finder”. Go up one directory and find the result in: Release-iphoneuniversal.
Files that need to be public in the framework should be added in the: Build Phase for the target Aggregate: ZeroMQ-iOS: Copy Files. Justin also warns (which I encountered), “Ensure that the header files are copied into place [at compile time] (XCode is known to mess this up on occasion)”.
