|
5 * |
|
6 * This file is based on "platform_windows.c" by Ryan C. Gordon and Gregory S. Read. |
|
7 * Windows Runtime-specific additions and changes are made by Martin "T-Bone" Ahrnbom. |
|
8 * |
|
9 * Instructions for setting up PhysFS in a WinRT Universal 8.1 app in Visual Studio 2013: |
|
10 * (hopefully these instructions will be somewhat valid with Windows 10 Apps as well...) |
|
11 * |
|
12 * 1. In Visual Studio 2013 (or later?), hit File -> New -> Project... |
|
13 * 2. On the left, navigate to Templates -> Visual C++ -> Store Apps -> Universal Apps |
|
14 * 3. In the middle of the window, select "DLL (Universal Apps)" |
|
15 * 4. Near the bottom, give the project a name (like PhysFS-WinRT) and choose a location |
|
16 * 5. In the Solution Explorer (to the right typically), delete all .cpp and .h files in |
|
17 * PhysFS-WinRT.Shared except targetver.h. |
|
18 * 6. In Windows Explorer, find the "src" folder of the PhysFS source code. Select all files |
|
19 * in the folder (ignore the "lzma" folder, we're not including 7Zip support because it's messy to compile). |
|
20 * Drag and drop all of the source files onto PhysFS-WinRT-Shared in Visual Studio. |
|
21 * 7. In Windows Explorer, find the file called "physfs.h". Copy this file into a folder of its own somewhere. |
|
22 * I suggest naming that folder "include". This will be your "include" folder for any projects using PhysFS. |
|
23 * 8. In the Solution Explorer, right click on PhysFS-WinRT.Windows and select Properties. Make sure that "Configuration" is set to |
|
24 * "All Configurations" and "Platform" is set to "All Platforms" near the top of the window. |
|
25 * 9. On the left, select "Precompiled Headers". Change "Precompiled Header" from "Use (/Yu)" to "Not Using Precompiled Headers". |
|
26 * 10. On the left, navigate to Configuration Properties -> C/C++ -> Preprocessor. In Preprocessor Definitions, add "_CRT_SECURE_NO_WARNINGS" |
|
27 * 11. Hit the OK button. |
|
28 * 12. Repeat steps 8-11 but for PhysFS-WinRT.WindowsPhone. |
|
29 * 13. In the Solution Explorer, find "platform_winrt.cpp" in PhysFS-WinRT.Shared. Right click on it and select "Properties". |
|
30 * 14. On the left, navigate to Configuration Properties -> C/C++ -> General. On the right, change "Consume Windows Runtime Extensions" |
|
31 * from "No" to "Yes (/ZW)". Hit "OK". |
|
32 * 15. Near the top of the Visual Studio window, select BUILD -> Batch Build... Hit "Select All", and then "Build". |
|
33 * 16. Now you have a bunch of .dll and .lib files, as well as an include folder that you can use in your projects! |
|
34 * 17. ??? |
|
35 * 18. Profit! |
