this happens whenever I try to compile gfind, why?

[FractalFusion]

Try the following:

Code: Select all

g++ -fpermissive -O3 -o gfind gfind.c

There will be some warnings (which without -fpermissive would be errors) but I don't think there's any way to get rid of them.

Ahh, that settles it. I was using gcc instead of g++. Thanks! *two and a half thumbs up*

So it asks me for the rule, I enter b3/s23, and then this happens:

Don't know why there are 3 lwsses.

Don't know why there are 3 lwsses.

The first two spaceships are the result of a c/2 glide-symmetric width-12 search. It finds two LWSSs side-by-side, because this is the shortest even-width glide-symmetric ship at this speed. The third LWSS is found in a 2c/4 asymmetric search.

If you want to find anything interesting with gfind, you will need to input different parameters. I gave a brief description of how to set up the search that finds copperhead here.

What does this mean?

It means it's progressing
