Hi Nathan, good tutorial! It could be useful to post this to the android section of the new openscenegraph joomla site:

Whilst you may be used to using the NDK tools in Cygwin, we > have only used CMD in this guide. The most important thing is to use the > latest stable version of OSG (3.0.1) - we found that the svn trunk version > just does not want to work. This is due to issues loading libraries as well > as some problems with OSG its self. > > As usual, your mileage may vary! > > Install make and MinGW > ====================== > - Download and install make from > http://gnuwin32.sourceforge.net/downlinks/make.php; > - Download and install MinGW from > http://sourceforge.net/projects/mingw/files/latest/download?source=files. > Don't forget to add the C++ compiler during the installation options; > - Add the install directories to your PATH.

Next; > - In Root Directory browse to <workspace>\osgAndroidExampleGLES1; > - Select the projects osg.AndroidExample.osgViewer and hit Finish; > - In Eclipse, open up jni\Android.mk and > set OSG_ANDROID_DIR to C:\Local\OpenSceneGraph-3.0.1\osginstall on line 7; > - You also need to add -lgnustl_static onto the end of line 21 > (LOCAL_LDLIBS); > > If you have an ndk version greater than android-ndk-r8b: > - Open C:\Local\OpenSceneGraph-Android\build\AndroidManifest.xml in a text > editor; > - > Add <uses-sdk android:targetSdkVersion="8" > android:minSdkVersion="8"></uses-sdk> as > a child of '<manifest>'.
