Compiling

You will need to install Go 1.9 or later.

Then, make sure to set up your GOPATH properly, eg. here is mine:

export GOPATH=${HOME}/go:${HOME}/src/lczero-client

Here, I've set my system install of go as the first entry, and then the leela-chess/go directory as the second.

Pre-reqs:

# (Bug workaround, using Tilps instead)
# go get -u github.com/notnil/chess
go get -u github.com/Tilps/chess

Then you just need to go build, and it should produce a client executable.

Running

First copy the lczero executable into the same folder as the client executable.

Then, run! Username and password are required parameters.

./client --user=myusername --password=mypassword

For testing, you can also point the client at a different server:

./client --hostname=http://127.0.0.1:8080 --user=test --password=asdf

Cross-compiling

One of the main reasons I picked go was it's amazing support for cross-compiling.

Pre-reqs:

GOOS=windows GOARCH=amd64 go install
GOOS=darwin GOARCH=amd64 go install
GOOS=linux GOARCH=amd64 go install

Building the client for each platform:

GOOS=windows GOARCH=amd64 go build -o client.exe
GOOS=darwin GOARCH=amd64 go build -o client_mac
GOOS=linux GOARCH=amd64 go build -o client_linux
