ZeroMQ-Framework

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 5.1.1, for iOS 7.1 and ...
... submod:zeromq4-x release:v4.0.4
... submod:czmq release:v2.2.0

Usage of the Framework is Paolo's Step 5, but I do have an errata!

Write a iOS client using the new ØMQ framework

just create a normal ios project
drag the ZeroMQ-iOS.framework folder in the Frameworks group (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++.

Recompilation

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)”.

Note: czmq_prelude.h: #include <crt_externs.h> // commented out, because removed from SDK by Apple

Brian's Notes

Configure zeromq

First run ./autogen.sh to create ./configure. Then run ./configure

Configure czmq

First run ./autogen.sh to create ./configure. Then run PKG_CONFIG_PATH=../zeromq4-x/src ./configure

czmq

Fixed to build for iOS

Xcode 6.1

update to OCUnit
