I looked at the LiDIA list. Christoff continues to promise the new version is coming, this time before he goes on vacation.
Apparently the compile problems are to do with the new gcc. Some kind person has posted the changes they made to get it working at length on the LiDIA list. I'll see if I can get it going and post timings for that too. I anticipate that all the different layers in LiDIA will make the class number code quite slow despite the algorithm being quite good. I will eventually code it from scratch myself, since this problem interests me greatly and fits in well with the quadratic sieve I've been writing. But obviously that's not going to happen overnight.
