MSIX Packaging SDK

DESCRIPTION

---

The MSIX Packaging format is an evolution of the Windows 8 era AppX package format as detailed at: 
https://blogs.msdn.microsoft.com/windowsappdev/2012/12/04/designing-a-simple-and-secure-app-package-appx/.  

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 Store, or 2nd/3rd party stores.  

The MSIX Packaging APIs that a client app would use to interact with .msix/.appx packages are a subset of those
documented here: https://msdn.microsoft.com/en-us/library/windows/desktop/hh446766(v=vs.85).aspx.  See 
./sample/ExtractContentsSample/ExtratContentsSample.cpp for additional details.

OVERVIEW

---

The MSIX Packaging SDK project includes cross platform API support for unpacking of .msix/.appx packages

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 all platforms instead of CoCreating IAppxFactory, a c-style export: CoCreateAppxFactory is 
                      provided.  See sample folder at root of package for cross platform consumption examples.

                      Finally, there is one export 'Unpack' that provides an simplified unpackage implementation.
                      
    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 [URL]
    
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.

BUILD

---

On Windows using Visual Studio 2017 nmake:
------------------------------------------
    makewin32.cmd

On Mac using make: 
------------------
    ./makemac
    ./makeios

On Linux using make:
--------------------
    ./makelinux
    ./makeaosp

How to compile for 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
