while Leela Zero compiles without problems. Possibly some C++17 code in there, as newer versions of gcc seem to have no problems?

Sorry about that. Tests are still broken in SAI. Did you try compiling with make from the directory sai/src?

Just to add to this: I managed to get gcc 8.3.1, and I was able to compile it while compiling it with 5.4.0 fails. Probably someone should identify the oldest gcc version which is able to compile it.

At least the "how to" page should be changed, as obviously C++14 compatibility isn't enough.
