Hi,
Thank you for the clarification. I followed the example, which gave me this
output:
christian@PROMETHEUS:/media/christian/DATA/osgAndroid/org.openscenegraph.android$
${ANDROID_NDK}/ndk-build
[armeabi] Compile++ thumb: jniosg-gles1 <= JNIosgViewer.cpp
jni/JNIosgViewer.cpp:23:28: fatal error: osg/observer_ptr: No such file or
directory
#include <osg/observer_ptr>
^
compilation terminated.
make: *** [obj/local/armeabi/objs/jniosg-gles1/JNIosgViewer.o] Error 1
I had a look into the Android.mk file, which gave me the following insights:
1) the makefile statically searches for the osg plugins of version 3.3.3 - I
hardcoded now 3.3.7 (which is the version I am using). Perhaps that could be
done with some environment variable or automatic parsing ? I would involve a
bit cmake code, I guess ...
2) the error above may come because "LOCAL_C_INCLUDES" is set, but
"LOCAL_CPP_INCLUDES" is not. Because OSG is C++ and because that distinction
matters for me with g++ in teh backend, I set the path.
After this minor adaptations, the compilation with the ndk actually progresses,
but has problems when starting to link the libraries:

I'll investigate that further by tomorrow.
I attached my new Android.mk, so you can have a look on the changes. it's the
one from the "org.openscenegraph.android/jni" folder.
Thank you!
Cheers,
Christian
