Compile a Contract

You can follow Create A Contract to create a simple Hello World contract.

Or example contract can found at this https://github.com/ultraio/eosio.cdt/tree/master/examples/hello

Compile via CLI

Follow these steps to compile your contract

Step 1

Navigate to the hello folder in examples (./examples/hello), you should then see the ./src/hello.cpp file

Step 2

Run the following commands

This will generate 2 files

• The compiled binary wasm, hello.wasm
• The generated ABI file, hello.abi

Compile via Cmake

You can have a look at CMakeLists.txt in ./examples/hello/src as an example on how to configure a Cmake file.

project(hello)

set(EOSIO_WASM_OLD_BEHAVIOR "Off")
find_package(eosio.cdt)

add_contract( hello hello hello.cpp )
target_include_directories( hello PUBLIC ${CMAKE_SOURCE_DIR}/../include )
target_ricardian_directory( hello ${CMAKE_SOURCE_DIR}/../ricardian )

Follow these steps to compile your contract

Step 1

Navigate to the hello folder in examples (./examples/hello), you should then see the ./src/hello.cpp file

Step 2

Run the following commands

$ mkdir build
$ cd build
$ cmake ..
$ make

This will generate 2 files under ./build/hello directory

• The compiled binary wasm, hello.wasm
• The generated ABI file, hello.abi
