Seems like a typo to me - note that the error message cribs about not finding "LFoo" whereas your function is "Java_Foo_myfunc". If your package name has LFoo, you need to call your function "Java_LFoo_myfunc".
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
