eosio-cpp -abigen hello.cpp -o hello.wasm

Question

Ubuntu 18.04.1 on VMware (Windows 10 64bit)

EOSIO v1.4.1

eosio.cdt-1.3.2

i just run the compiler like this :

win@ubuntu:~/eos$ eosio-cpp -abigen hello.cpp -o hello.wasm

then, the terminal stopped and the compiler created 2 files.

hello.wasm

hello.wasm.tmpfc9a0c1

because the terminal stopped, i entered ^C. then, the 2 files changed into :

hello.abi

hello.wasm

the abi file is good. but wasm file is broken. of course, i cannot set the contract.

why doesn't the compiler work properly??

i use the following hello.cpp code from the eosio.cdt example.

#include <eosiolib/eosio.hpp>

using namespace eosio;

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

      ACTION hi( name user ) {
         print( "Hello, ", name{user} );
      }
};

EOSIO_DISPATCH( hello, (hi) )

Answer 1

solved and it was because of the virtual machine.

Answer 2

You should be inside of the contract folder before calling eosio-cpp.

Try this:

$ cd ~/eos/contracts/hello
~/eos/contracts/hello/$ eosio-cpp -abigen hello.cpp -o hello.wasm
