contract compilation of 'eosio.bios' fails

Question

I am trying to setup Local Multi-Node Testnet using the version 2.0.7.

Clone the sysytem contracts from the repo as follows.

      git clone https://github.com/EOSIO/eosio.contracts --branch master --single-branch

Creating wasm and abi files using the following command.

      cd eosio.contracts/contracts/eosio.bios
      eosio-cpp -I include -o eosio.bios.wasm src/eosio.bios.cpp --abigen

But it generates the following compilation error.

    In file included from /home/user/eosio/eosio.contracts/contracts/eosio.bios  /src/eosio.bios.cpp:1:
    include/eosio.bios/eosio.bios.hpp:237:50: error: no member named  'producer_authority' in namespace 'eosio'
         void setprods( const std::vector<eosio::producer_authority>& schedule );
                                      ~~~~~~~^

   check( is_feature_activated( feature_digest ), "protocol feature is not activated" );

    4 errors generated.
    abigen error

Did anyone face this similar issue?Help is appreciated .

If you want to build a single contract with eosio.cdt you would need to modify the code.

Just use the build-script build.sh (located in the eosio.contracts-directory) to compile all system-contracts at once, without the need to modify any of them.
