How to build eosio.contracts

Preconditions

Ensure an appropriate version of eosio.cdt is installed. Installing eosio.cdt from binaries is sufficient, follow the eosio.cdt installation instructions steps to install it. To verify if you have eosio.cdt installed and its version run the following command

eosio-cpp -v

Build contracts using the build script

To build contracts alone

Run the build.sh script in the top directory to build all the contracts.

To build the contracts and unit tests

1. Ensure an appropriate version of eosio has been built from source and installed. Installing eosio from binaries is not sufficient. You can find instructions on how to do it here in section Building from Sources.
2. Run the build.sh script in the top directory with the -t flag to build all the contracts and the unit tests for these contracts.

Build contracts manually

To build the eosio.contracts execute the following commands.

On all platforms except macOS:

cd you_local_path_to/eosio.contracts/
rm -fr build
mkdir build
cd build
cmake ..
make -j$( nproc )
cd ..

For macOS:

cd you_local_path_to/eosio.contracts/
rm -fr build
mkdir build
cd build
cmake ..
make -j$(sysctl -n hw.ncpu)
cd ..

After build:

• If the build was configured to also build unit tests, the unit tests executable is placed in the build/tests folder and is named unit_test.
• The contracts (both .wasm and .abi files) are built into their corresponding build/contracts/\<contract name> folder.
• Finally, simply use cleos to set contract by pointing to the previously mentioned directory for the specific contract.

How to deploy the eosio.contracts

To deploy eosio.bios contract execute the following command:

Let's assume your account name to which you want to deploy the contract is testerbios

cleos set contract testerbios you_local_path_to/eosio.contracts/build/contracts/eosio.bios/ -p testerbios

To deploy eosio.msig contract execute the following command:

Let's assume your account name to which you want to deploy the contract is testermsig

cleos set contract testermsig you_local_path_to/eosio.contracts/build/contracts/eosio.msig/ -p testermsig

To deploy eosio.system contract execute the following command:

Let's assume your account name to which you want to deploy the contract is testersystem

cleos set contract testersystem you_local_path_to/eosio.contracts/build/contracts/eosio.system/ -p testersystem

To deploy eosio.token contract execute the following command:

Let's assume your account name to which you want to deploy the contract is testertoken

cleos set contract testertoken you_local_path_to/eosio.contracts/build/contracts/eosio.token/ -p testertoken

To deploy eosio.wrap contract execute the following command:

Let's assume your account name to which you want to deploy the contract is testerwrap

cleos set contract testerwrap you_local_path_to/eosio.contracts/build/contracts/eosio.wrap/ -p testerwrap
