Hi,
In the meanwhile, I was working further on the topic - and cracked it this
time, I think. First and foremost, I use OpenSceneGraph 3.3.8 (still) and
compile it for Android, while having the necessary 3rdParty-folder inside the
OpenSceneGraph root folder (little suggestion: at some point this may be
changed in the makefiles to search that folder by environment variable path,
such as the data folder ...). I just define the GLES profile and the android
platform and build it. Next:
A) For generating the PREBUILT_STATIC_LIBRARY, I took a sip from the OpenCV
recipe that defines a local mk-file function that builds each 3rd Party
dependency for the android package.
B) These local prebuilds are then referred to via
"LOCAL_WHOLE_STATIC_LIBRARIES", which is necessary so that the ndk-build linker
finds all referred functions. That's the actual behaviour I kind'a expected in
any case for a STATIC library (containing all content), bust as Jan pointed
out: Android NDK - you'll never know what you get :D
This way, it works for me now, as I can load osg.Image() within Android using a
jpeg image, in order to texture a geometry.
Manual and code submission are still on my agenda. The appended make file is
afree-for-all to try out - just take the ".txt" extension away.
Cheers,
Christian
