recompile ourchain

call stack
ourcontract-rt contracts_example test | V main in ourcontract-rt.c | V start_runtime in libourcontract.c | V call_contract in libourcontract.c | V contract_main in contracts_example/test/code.so using dlsym | V // (1) develop function call for contract test_libsnark in libourcontract.c | V // (2) using dynamic library to call c++ code in libsnark and provide function simultaneously test_libsnark in zk-tool/src/test/test_libsnark.cpp (by using path to OURZKLIB) | V using any libsnark libraries -
(1)and(2)are where we develop function call for user -
check out files under
ourchain/src/zk-tool/src
- only add function into
ourcontract.handlibourcontract.c, and add addtional folderzk-toolunderourchain/src
