Multiple stockfish wasms for use in lichess.org web analysis
# Example: Clean and make all debug builds for node with SAFE_HEAP
./build.py --flags='-O0 -g3 -sSAFE_HEAP' --node all clean
or to avoid installing or changing your emscripten version, use ./build-with-docker.sh
:
./build-with-docker.sh --flags='-O3' all clean
omit --node
for default web builds
use --flags
to override the default emcc flags which are -O3 -DNDEBUG --closure=1
check ./build.py --help
for the latest targets
./build.py
downloads sources to the ./fishes
folder then applies diffs from the ./patches
folder.
Edit the Stockfish sources freely. But to contribute your edits, use a patch file
# Example: Update `sf16-7.patch` with your source changes:
cd fishes/sf16-7
git diff > ../../patches/sf16-7.patch
