Hi Julius, Seems that the ndk is not finding the libraries in the path.
Are the generated .a files in this path? -L/home/jus/working/osg/osg/build_gles1/lib Is OSG generated with armeabi?, I think the ndk sets the armeabi-v7 version by default, and osgAndroid is configured with armeabi in the Application.mk maybe that is giving some troubles.
