That must be treated as just eater-to-diplet reaction. Spaceship-to-static-object reaction must be done when a spaceship passes by a static object.

Re: Golly 2.7 is now available

Typing "sudo apt-get install golly" in Linux Ubuntu Yakkety (16.10) installs Golly 2.7.

And when I go to "Control -> Set Rule...", I get a blank window and I can't close it.

It appears MinGW doesn't support C++14 yet.

Re: NDosearch 1.0

There are so many problems... Also,how to configure NDos::GOL? Your compiler must support at least C++14. NDos::GOL, for both B(Birth) and S(Survival), ith (start from 0th) least significant bit represents i neighbors. By default, NDos::GOL.B is 0b000001000, so it represents B3, and NDos::GOL.S is ...
