Hi. What a great start of the new year, Now I got Poplog 16 to work!
The magic that got it to work on my Linux Ubuntu 18.04 box was the -nopie flag to getpoplog.sh . Excellent! There are still some issues that I will check out in more detail, but running all the first 50 Project Euler programs is now 2s faster than the earlier 15.65 version. (See http://hakank.org/poplog/ for the programs.) Happy New Year to all!
