问题

I have an crossplatform implementation of own protocol, data-structures and logic written on Haxe. How I can build and use it in my enterprise-application (with native UI) for iOS and OSX?

How to create iOS- / OSX- library from Haxe and use it in native application

Actuality: 12.2014; HXCPP-ver.: 3.1.39~git.

Dependency: hxcpp

1. Haxe -> Library

Create a new Haxe-project with main class named HxModule.

src/HxModule.hx

class HxModule
{
    public static function main()
    {
        Sys.println('Hello from HxModule: "${test()}"');
    }

    @:headerCode
    public static function test():Int
    {
        return 101;
    }
}

build.hxml

-main HxModule
-cp src

-lib hxcpp

# this is for Mac OS X:
-D HXCPP_M64

# this is required on Windows. the "d" stands for debug:
#-D ABI=-MTd
--each

# at this phase we create a binary for tests
-cpp out/cpp/module


--next
# at this phase we create a binary for tests
-cpp out/cpp/module

-D static_link
-D actuate

Build: $ haxe buid.hxml

2. Xcode-project <- Library

Create a new Xcode-project. It can be for OSX or iOS, Application or Cocoa Framework.
In the 'Project' / 'Build Setting' / 'Header Search Paths' add paths to dependencies: (all paths must be full/not-relative and recursive)
1. out/cpp/module/include - you have to fix it to full path;
2. {your-haxelib-repo}/hxcpp/{version}/include - {here-yours};
3. /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include
In the 'Project' / 'Build Settings' / 'Apple LLVM 6.0 - Language - C++' change values:
- 'C++ Language Dialect' = GNU++11 [-std=gnu++11]
- 'C++ Standard Library' = libstdc++ (GNU C++ standard library)
In the 'Project' / 'Build Phases' / 'Link Binary With Libraries':
- HxModule.a
Rename file: AppDelegate.m -> AppDelegate.mm
Edit AppDelegate.mm:

AppDelegate.mm

#import "AppDelegate.h"
#import "HxModule.h"

@implementation AppDelegate
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    NSLog(@"test: %d", ((int)HxModule_obj::test()));
}
@end

Additionally for autocomplete and better navigation you can add into Xcode-project the reference groups from directories:

include from output of Haxe;
include from haxelib hxcpp.

Possible problems:

At the time when this text was written only one possible issue. It can be solved by editing the file {haxelib:hxcpp}/include/hxcpp.h. Simply add a few lines at the beginning of the file:

{haxelib:hxcpp}/include/hxcpp.h

#ifndef HXCPP_H
#define HXCPP_H

// Standard headers ....

// Custom override by @suhinini
#define Class HxcppClass

// Basic mapping from haxe -> c++

typedef int Int;
typedef bool Bool;


// Windows hack
#define NOMINMAX


#ifdef _MSC_VER
   #include <typeinfo.h>
   namespace hx { typedef ::type_info type_info; }
...

see after // Standard headers .....

Example project.
