MSIX Packaging SDK

DESCRIPTION

The MSIX Packaging SDK project is an effort to enable developers on a variety of platforms to package and unpackage 
application packages for the purposes of distribution from either the Microsoft Windows Apps Store, or 
2nd/3rd party stores.  To that end, the file format of these packages need to be in a format that is easily 
digestible to through the Microsoft Windows Apps Store back-end ingestion processes; which means that the 
file format for these packages will be an .AppX package.

OVERVIEW

The MSIX Packaging SDK project includes:

1. Cross platform API support for unpacakge of .appx package

The scheduling of the highlevel work listed above will be determined with respect to the relative priorities.

The MSIX Packaging SDK project includes:

    msix            - A shared library (DLL on Win32, dylib on MacOs, SO on Linux and Android) that exports a subset
                      of the functionality contained within appxpackaging.dll on Windows.  See:
                      https://msdn.microsoft.com/en-us/library/windows/desktop/hh446766(v=vs.85).aspx
                      for additional details.

                      On platforms that do not support COM (e.g. anything _other_ than Windows) instead of
                      CoCreating IAppxFactory, a c-style export: CoCreateAppxFactory is provided instead.
                      See sample folder at root of package for cross platform consumption examples

                      Finally, there is one exports 'Unpack' that provides an simplified unpackage implementations.
                      
    makemsix        - A command line wrapper over the Unpack implementation.  This tool exists
                      primarily as a means of validating the implementation of the MSIX Packaging SDK internal
                      routines and is compiled for Win32, MacOS, and Linux platforms.

SETUP INSTRUCTIONS

Step 1: Clone the repository:
    git clone https://microsoft.visualstudio.com/DefaultCollection/_git/xPlatAppx
Step 2: Initialize git submodules:
    git submodule init
    git submodule update

ISSUES

If you are using Visual Studio 2017 and you run into errors about not being able to find the v140 toolset, then 1st:
    step 1: Install the Microsoft Build Tools (https://chocolatey.org/packages/microsoft-build-tools)
    step 2: start -> visual studio installer -> Visual Studio Build Tools 2017 -> Modify the 2014 toolset -> individual components 
    step 3: make sure that VC++ 2015.3 v140 toolset for desktop is selected and then unselect VC++ 2017 141 toolset
    step 4: close, then re-open the solution.

File->Open Folder->navigate to project root and select "CMakeLists.txt"

See: https://blogs.msdn.microsoft.com/vcblog/2016/10/05/cmake-support-in-visual-studio/
for details regarding how to configure your environment.

Xcode clients: 
--------------
open terminal, from project root:
mkdir build && cd build && cmake -DMACOS=on -G"Xcode" ..
open xcode
File->Open->navigate to project root/build and select "Project.xcodeproj"

See: https://www.johnlamp.net/cmake-tutorial-2-ide-integration.html#section-Xcode for additional details

Make Android on Windows:
------------------------
Unpack the latest Android NDK to c:\android-ndk
Unpack Ninja-build to c:\ninja
Add c:\ninja to the path environment variable
Create a folder under the root of the enlistment called "android", cd into that folder, then run the following command to create ninja build files:

cmake -DCMAKE_ANDROID_NDK=c:/android-ndk ^
    -DCMAKE_ANDROID_NDK_TOOLCHAIN_VERSION=clang ^
    -DCMAKE_SYSTEM_NAME=Android ^
    -DCMAKE_SYSTEM_VERSION=19 ^
    -DCMAKE_ANDROID_ARCH_ABI=x86 ^
    -DCMAKE_ANDROID_STL_TYPE=c++_shared ^
    -DCMAKE_BUILD_TYPE=Release ^
    -DAOSP=on ^
    -G"Ninja" ..

To compile, run the following command from the android folder:

ninja
