I couldn't find any information on how to automatically include the ricardian clauses in the abi. I always get the error:

abi_generator.hpp:68 ricardian_contracts ] Warning, no ricardian clauses found for

I found out that the name must be ${contract}_rd.md. But the abi_generator doesn't even resolve the correct contract name in my contract.

  1. How is the contract name determined? It looks like you need to use the EOSIO_ABI macro in some way. How to do it when I cannot use this macro?
  2. I tested it with the example contract: eosiocpp -n hello and create files for hello_rc.md, hello.hi_rc.md. Running eosiocpp -g hello.abi hello.cpp creates the abi with no warnings, but the clauses are empty in the abi file. Why are they empty? Do they need a specific format?

  • Any way to do it with eosiocpp? Aug 2, 2018 at 11:31
  • If there is a flag for creating rc's with eosiocpp, I do not know it.

  • eosio-cpp cannot find the ricardian files, no matter what I tried. The -R path does not help. The eosio-init produces the same result ( "empty ricardian clause file") (BTW the message is wrong, it means the CONTRACT.contracts.md file not found) All the official examples do not work either... I even tried to debug the eosio-cpp to find the problem, but the eosio.cdt does not compile on Ubuntu... Not good... Can anyone actually compile a contract with ricardian files?

The eosiocpp compiler was the old deprecated way of compiling the c++ into wasm contracts.

The new way uses a compiler called eosio-cpp, which is very confusing.

With eosio.cdt, you can generate a CMake build system using eosio-init, and it will generate the cmake command target_ricardian_directory, where you should specify your ricardian contract files. These will then be automatically integrated into the compiled ABI file.
