Stockfish 210720 with NNUE

[kranium]

What version of g++? Yours must be quite old.

What do you get if you enter the following at a command line?

g++.exe -v

Yeah, it's from 2014...

I get:

gcc version 4.9.2 (x86_64-posix-seh-rev1, Built by MinGW-W64 project)

However, this compiles Stockfish dev just fine. Do I need to upgrade or can I make changes to source so it compiles with this one?

C++17 is critical for the nnue codebase...
many features are available since GCC 5
full support since 7 ?

Thanks, updated to GCC 10.

make profile-build ARCH=x86-64 COMP=mingw still doesn't work.

make profile-nnue ARCH=x86-64 COMP=mingw works, but throws these warnings:



Then produces a stockfish that when ticking the EvalNNUE tickbox kills the nodes per second to 1/10 from normal, so I don't think I'm compiling correctly.
