|

*
|
||||
* This file is based on "physfs_platform_windows.c" by Ryan C. Gordon and Gregory S. Read.
|
||||
* Windows Runtime-specific additions and changes are made by Martin "T-Bone" Ahrnbom.
|

*
|
||||
* Instructions for setting up PhysFS in a WinRT Universal 8.1 app in Visual Studio 2013:
|
||||
* (hopefully these instructions will be somewhat valid with Windows 10 Apps as well...)
|
||||
*
|
||||
* 1. In Visual Studio 2013 (or later?), hit File -> New -> Project...
|
||||
* 2. On the left, navigate to Templates -> Visual C++ -> Store Apps -> Universal Apps
|
||||
* 3. In the middle of the window, select "DLL (Universal Apps)"
|
||||
* 4. Near the bottom, give the project a name (like PhysFS-WinRT) and choose a location
|
||||
* 5. In the Solution Explorer (to the right typically), delete all .cpp and .h files in
|
||||
* PhysFS-WinRT.Shared except targetver.h.
|
||||
* 6. In Windows Explorer, find the "src" folder of the PhysFS source code. Select all files
|
||||
* in the folder.
|
||||
* Drag and drop all of the source files onto PhysFS-WinRT-Shared in Visual Studio.
|
||||
* 7. In Windows Explorer, find the file called "physfs.h". Copy this file into a folder of its own somewhere.
|
||||
* I suggest naming that folder "include". This will be your "include" folder for any projects using PhysFS.
|
||||
* 8. In the Solution Explorer, right click on PhysFS-WinRT.Windows and select Properties. Make sure that "Configuration" is set to
|
||||
* "All Configurations" and "Platform" is set to "All Platforms" near the top of the window.
|
||||
* 9. On the left, select "Precompiled Headers". Change "Precompiled Header" from "Use (/Yu)" to "Not Using Precompiled Headers".
|
||||
* 10. On the left, navigate to Configuration Properties -> C/C++ -> Preprocessor. In Preprocessor Definitions, add "_CRT_SECURE_NO_WARNINGS"
|
||||
* 11. Hit the OK button.
|
||||
* 12. Repeat steps 8-11 but for PhysFS-WinRT.WindowsPhone.
|
||||
* 13. In the Solution Explorer, find "physfs_platform_winrt.cpp" in PhysFS-WinRT.Shared. Right click on it and select "Properties".
|
||||
* 14. On the left, navigate to Configuration Properties -> C/C++ -> General. On the right, change "Consume Windows Runtime Extensions"
|
||||
* from "No" to "Yes (/ZW)". Hit "OK".
|
||||
* 15. Near the top of the Visual Studio window, select BUILD -> Batch Build... Hit "Select All", and then "Build".
|
||||
* 16. Now you have a bunch of .dll and .lib files, as well as an include folder that you can use in your projects!
|
||||
* 17. ???
|
||||
* 18. Profit!
