So, I downloaded the 3.3.7 developer version of OpenSceneGraph and ran the
cmake command as given in the link for "Building OpenSceneGraph 3.3.2-3.4.x
for Android" (sth. like it).
After a bit of hassle, it compiled fine.
I also put the 3rdParty folder inside the OSG root folder, but cmake reported
that CURL, Jpeg, Tiff etc. are missing - well, weird, but not urgent for now.
I use the svn version rc2, and compile with OPENGL_PROFILE "GLES2".
Then, I imported the GLES1/2 examples in Eclipse, modified the Android.mk so
to link to the installation folder (btw: still used static libs) and using
gnustl_static, ran ndk-build, and this is the output:

Hence, the static linker does not find the function
osgViewer::View::addEventHandler(...) in the library. This is the GLES1
example. I guess it is no surprise it doesn't find THAT (shouldn't it be
osgViewer::Viewer::addEventHandler ?!), rather the question is where this is
coded ? I assume there must be sth. going on in the DOTOSGWRAPPER of
osgViewer ...
The output for the osgViewerGLES2, configured and setup the same way, looks
as follows:

Also there, it doesn't find the osgViewer::View::add..., but he also looks
for the GLES1 fixed functionality pipeline calls that surely don't exist.
The question for the is rather why the GLES2 example (I swear by god, it is
the GLES2 example), asks for GLES1 functions ?!
This is how far I got today. Any help would be highly appreciated. I also
append my cmake-line.

Tomorrow, I go and try the osgAndroid repo out.
Best Regards already,
Christian
