done in the build directory for the app!


For more complex projects, follow these instructions:
    
1. Copy the android-project directory wherever you want to keep your projects
   and rename it to the name of your project.
2. Move or symlink this SDL directory into the "<project>/jni" directory
3. Edit "<project>/jni/src/Android.mk" to include your source files
4. Run 'ndk-build' (a script provided by the NDK). This compiles the C source

If you want to use the Eclipse IDE, skip to the Eclipse section below.

5. Create "<project>/local.properties" and use that to point to the Android SDK directory, by writing a line with the following form:

       sdk.dir=PATH_TO_ANDROID_SDK

6. Run 'ant debug' in android/project. This compiles the .java and eventually 
   creates a .apk with the native code embedded
7. 'ant debug install' will push the apk to the device or emulator (if connected)

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

This build uses the Android NDK module system.

Instructions:
1. Copy the android-project directory wherever you want to keep your projects
   and rename it to the name of your project.
2. Rename "<project>/jni/src/Android_static.mk" to "<project>/jni/src/Android.mk"
   (overwrite the existing one)
3. Edit "<project>/jni/src/Android.mk" to include your source files
4. create and export an environment variable named NDK_MODULE_PATH that points
   to the parent directory of this SDL directory. e.g.:

       export NDK_MODULE_PATH="$PWD"/..

5. Edit "<project>/src/org/libsdl/app/SDLActivity.java" and remove the call to
   System.loadLibrary("SDL2").
6. Run 'ndk-build' (a script provided by the NDK). This compiles the C source


================================================================================
 Customizing your application name
================================================================================

	mkdir -p $(bundle_contents)/Resources
	echo "APPL????" > $(bundle_contents)/PkgInfo
	$(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/

You should replace EXE_NAME with the name of the executable. APP_NAME is what
will be visible to the user in the Finder. Usually it will be the same
as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME 
usually is "TestGame". You might also want to use `@PACKAGE@` to use the package
name as specified in your configure.in file.

If your project builds more than one application, you will have to do a bit
more. For each of your target applications, you need a separate rule.

If you want the created bundles to be installed, you may want to add this
rule to your Makefile.am:

Raspbian system root and the cross compilation tools. We'll assume these tools
will be placed in /opt/rpi-tools

    sudo git clone --depth 1 https://github.com/raspberrypi/tools /opt/rpi-tools

You'll also need a Rasbian binary image.
Get it from: http://downloads.raspberrypi.org/raspbian_latest 
After unzipping, you'll get file with a name like: "<date>-wheezy-raspbian.img"
Let's assume the sysroot will be built in /opt/rpi-sysroot.

    export SYSROOT=/opt/rpi-sysroot
    sudo kpartx -a -v <path_to_raspbian_image>.img
    sudo mount -o loop /dev/mapper/loop0p2 /mnt
    sudo cp -r /mnt $SYSROOT
    sudo apt-get install qemu binfmt-support qemu-user-static

/* This is a drop-in replacement for the C library's |qsort()| routine.
 *
 * It is intended for use where you know or suspect that your
 * platform's qsort is bad. If that isn't the case, then you
 * should probably use the qsort your system gives you in preference
 * to mine -- it will likely have been tested and tuned better.
 *
 * Features:
 *   - Median-of-three pivoting (and more)
 *   - Truncation and final polishing by a single insertion sort
 *   - Early truncation when no swaps needed in pivoting step
 *   - Explicit recursion, guaranteed not to overflow
 *   - A few little wrinkles stolen from the GNU |qsort()|.
 *     (For the avoidance of doubt, no code was stolen, only
 *     broad ideas.)
 *   - separate code for non-aligned / aligned / word-size objects
 *
 * Earlier releases of this code used an idiosyncratic licence
 * I wrote myself, because I'm an idiot. The code is now released
 * under the "zlib/libpng licence"; you will find the actual
 * terms in the next comment. I request (but do not require)
 * that if you make any changes beyond the name of the exported
 * routine and reasonable tweaks to the TRUNC_* and
 * PIVOT_THRESHOLD values, you modify the _ID string so as
 * to make it clear that you have changed the code.
 *
 * If you find problems with this code, or find ways of
 * making it significantly faster, please let me know!

 * foreseeable future, is
