using namespace eosio;

class hello : public eosio::contract {
public:
using contract::contract;

  /// @abi action

  } 

};

EOSIO_ABI( hello, (hi) ) `

@OuterSpaceTears how are you generating the ABI file?
Which OS are you using?

@elmato I get the same thing and I’m on Ubuntu 17.10 x64

Can you paste the command you are using to generate hello.abi and the output it gives?

[ZeroPointThree17]

I needed to sudo make install on the eos/build dir and tried generating the abi again and it worked! Thanks @elmato for helping me find what the issue was.

@OuterSpaceTears looking at the empty ABI file format, it seems that you are using an older version of the abi generator (eosio-abigen) which is called by eosiocpp.

Make sure you are doing make install after building the project.

I implemented./eos_build.sh, did not execute sudo make install, and solved this problem through sudo make install. Thank you very much.
