Error messages from cmd after compiling?

[rwbc]

Hi Michael,

After a successful compiling (with -static and -march=native added) under WIN with just two warnings, a first test from cmd shows nearly two thousands of error lines about invalid attack tables for Bishop and Rook.

After this MisterQueen can still be started with the uci command and reacts to 'go infinite' with b1c3 (no pv, no info though) Haven't tried yet if it might play a game under a GUI despite the error messages in the beginning.

Any idea?

This might be your problem:

Ok, the problem was that wasm has diferent sizes for data types. There was an overflow issue. The solution was to change the following line 4 in bb.h:

define BIT(sq) (1L << (sq))

to

define BIT(sq) (1LL << (sq))

[rwbc]

Hooray! Thanks for the quick hint.

Finally I can add MisterQueen to the XB/UCI chronology, except you won't like to be there? https://rwbc-chess.de/ https://docs.google.com/spreadsheets/d/1GXoy3lGhdKPJbatdw2_2dhWT3TkpthPcNtHs51MQydM BTW it would be nice if a version number would exist. Ofc I can still add the last commit date to the binary.

This is on an old quadcore in case you wonder about the speed:

May be you are even willing to add three time repetition detection after all the years? :)
