Compilation

Instruction on how to compile from source.
You will need a recent version of the stable rust compiler. Typically this can be done using rustup.

rustup update

Then you will need to download or sync the repository from github.

Finally, use cargo, with some options, to compile.

Windows

; modern cpu version
set RUSTFLAGS=-C target-feature=+crt-static -C target-cpu=x86-64-v3 && cargo b --profile=tournament 

; if the above fails the search test suite below try compiling for an older cpu
set RUSTFLAGS=-C target-feature=+crt-static -C target-cpu=generic && cargo b --profile=tournament

Linux

# on linux you will want to install the musl library for better portability between Linux systems.
rustup target add x86_64-unknown-linux-musl

# modern cpu version
RUSTFLAGS="-C target-cpu=x86-64-v3" cargo b --profile=tournament --target x86_64-unknown-linux-musl

# older cpu
RUSTFLAGS="-C target-cpu=generic" cargo b --profile=tournament --target x86_64-unknown-linux-musl

# remove debug symbols
strip ./target/x86_64-unknown-linux-musl/tournament/odonata

Testing

# help with command line options 
.\target\tournament\odonata.exe help

# search performance on a test suite (on Windows)
.\target\tournament\odonata.exe search -t depth=10

# search performance on a test suite (on Linux)
./target/x86_64-unknown-linux-musl/tournament/odonata search -t depth=10

# perft performance 
.\target\tournament\odonata.exe uci "perft 6"

# show compilation flags
.\target\tournament\odonata.exe uci "compiler"

# evaluate (statically) a board position
.\target\tournament\odonata.exe uci "position fen r1b2rk1/1p3pp1/pn1b1n1p/2pPp3/Pq6/2N1PNB1/BP2QPPP/3R1RK1 b - - 4 16; eval" 

# run a depth 5 search from a FEN position
.\target\tournament\odonata.exe uci "position fen r1b2rk1/1p3pp1/pn1b1n1p/2pPp3/Pq6/2N1PNB1/BP2QPPP/3R1RK1 b - - 4 16; go depth 5" 

# run the interactive uci engine (more usually invoked through a chess GUI)
.\target\tournament\odonata.exe
