Clone the repo and submodules. Because the submodules we used contains submodules too, we should add --recursive parameter.

git submodule update --init --recursive

Build blst archive (only contract checkpoint needs it now, so you can skip this step if checkpoint is not needed)

The docker version has some problem, so we have to execute the following beforehand to update no_asm.h & vect.h mannually.

cd common/blst/ckb-lib-secp256k1-blst/deps/blst
git apply ../../blst/blst.patch

After runing the above command, you should see changes in no_asm.h & vect.h.

Then, We can build lib blst:

cd common/blst/ckb-lib-secp256k1-blst
make all-via-docker

Prepare work to run Eth sig releated contracts (stake at, delegate at, withdraw at) :

cd common/c/secp256k1_extra
cp secp256k1_data_info.h ../deps/ckb-production-scripts/build/
cp libsecp256k1-config.h ecmult_static_context.h ecmult_static_pre_context.h ../deps/ckb-production-scripts/deps/secp256k1/src

Meanwhile, to avoid duplicate symbol error, we must remove line 175 to 472 in common/c/deps/ckb-production-scripts/c/blake2b.h.

Build CKB contracts:
You can use capsule build to build all contracts at once. or build sepecific contract using following commands.

capsule build -n selection
capsule build -n checkpoint
...

run tests: You can run cargo test to run all tests. Also, you can run test for specific contract using following commands.

cd tests
cargo test test_selection_success -- --nocapture
cargo test test_checkpoint_success -- --nocapture
...
