#ofxiOSBoost for Boost 1.58.0

Boost C++ Libraries 1.58.0 Pre-compiled for iOS

• Addon with Boost 1.58.0 for iOS / Xcode
• Precompiled library and Command to build yourself
• Master is currently a Fat Lib of All Standard Architectures
• Check Branches for others or to be specific
• Designed for use as an open frameworks addon, however should definitely work for other iOS projects
• Built with clang++ and using libc++ and std=c++11
• License: See Boost License LICENSE.MD

============

Where to checkout?

• For openframeworks: Checkout in the addons folder like so: addons/ofxiOSBoost
• For others: anywhere you please

============

How To Link to an Xcode Project?

In Xcode Build Settings for your project:

• Add to Library Search Paths ( LIBRARY_SEARCH_PATHS ) $(SRCROOT)/../../../addons/ofxiOSBoost/libs/boost/lib/ios
• Add to Header Search Paths ( HEADER_SEARCH_PATHS )
  $(SRCROOT)/../../../addons/ofxiOSBoost/libs/boost/include

In the Target under Build Phases

• Add to 'Link Binary With Libraries' the boost.a found in the ofxiOSBoost/libs/boost/lib/ios directory.

If not openFrameworks just add the libs/boost/include to Header Search Paths and the libs/boost/ios to Library Search Paths

============

Architectures in Pre-Build Library (Fat Lib)

See the other branches on this repository (All libc++ std=c11)

• arm64 : (iOS 7, 8 64bit only) [iPhone 5S, iPhone 6, iPhone 6 Plus, iPad Air]
• armv7 : (iOS 5, 6, 7, 8) [All devices]
• i386 : (iOS Simulator iPad 2, 3, 4, iPhone 4S, 5, 5C)
• x86_64: (iOS Simulator iPad Air, iPhone 5S, iPhone 6, iPhone 6 Plus)

Check Apple's Hardware sheet if you need to verify: Apple's Device compatibilty Matrix

** Armv7s has been removed due to Apple phasing our the requirement from the STANDARD_ARCHITECTURES.

============

How to Build?

1. You don't need to. This has the pre-compiled versions of BOOST for you to use
2. If you would prefer to build it yourself checkout the script included in the scripts directory.

=============

How to use Build Script

• Download files (suggested you download the files to addons/ofxiOSBoost for openFrameworks)
• Double click and run scripts/build-libc++.command (this will download the 1.58.0 version of boost and begin compiling the library).
• Once completed in the terminal continue with the next steps.
• Add the ofxiOSBoost to your project (src and libs for your chosen architecture)`

Alternative Build Script:

• Build using libstdc++ by running the scripts/build-libstdc++.command

Clean script

• Run the clean script from scripts/cleanAll.command to remove pre-compiled code and the final built library

Troubleshooting:

Undefined symbols link error (For libc++ release)

If you use libraries like serialization you might see link errors in Xcode 6 especially when the framework was built using --with-c++11 flag.

    Undefined symbols for architecture i386:
    "std::__1::__vector_base_common<true>::__throw_length_error() const", referenced from:
    void std::__1::vector<boost::archive::detail::basic_iarchive_impl::cobject_id, std::__1::allocator<boost::archive::detail::basic_iarchive_impl::cobject_id> >::__push_back_slow_path<boost::archive::detail::basic_iarchive_impl::cobject_id>(boost::archive::detail::basic_iarchive_impl::cobject_id&&) in boost(libboost_serialization_basic_iarchive.o)

You have to change your project or target build settings.

Under Apple LLVM 6.0 - Language - C++ make the following changes

C++ Language Dialect to C++11 [-std=c++11] C++ Standard Library to libc++ (LLVM C++ standard library with C++11 support)

Parse errors when including boost/type_traits.hpp

If you happen to include <boost/type_traits.hpp> header file, you may see compile errors like this

Unexpected member name of ';' after declaration specifiers

To fix this problem, include the following line in your porject ***-Prefix.pch file.

#define __ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES 0
