EOSIO.CDT (Contract Development Toolkit) is a suite of tools used to build EOSIO contracts
EOSIO.CDT is a toolchain for WebAssembly (WASM) and set of tools to facilitate smart contract development for the EOSIO platform. In addition to being a general purpose WebAssembly toolchain, EOSIO specific optimizations are available to support building EOSIO smart contracts. This new toolchain is built around Clang 7, which means that EOSIO.CDT has the most currently available optimizations and analyses from LLVM, but as the WASM target is still considered experimental, some optimizations are incomplete or not available.
As of this release two new repositories are under the suite of tools provided by EOSIO.CDT. These are the Ricardian Template Toolkit and the Ricardian Specification. The Ricardian Template Toolkit is a set of libraries to facilitate smart contract writers in crafting their Ricardian contracts. The Ricardian specification is the working specification for the above mentioned toolkit. Please note that both projects are alpha releases and are subject to change.
EOSIO.CDT currently supports Mac OS X brew, Linux x8664 Debian packages, and Linux x8664 RPM packages.
If you have previously installed EOSIO.CDT, run the
uninstallscript (it is in the directory where you cloned EOSIO.CDT) before downloading and using the binary releases.
brew tap eosio/eosio.cdt brew install eosio.cdt
brew remove eosio.cdt
$ wget https://github.com/eosio/eosio.cdt/releases/download/v1.7.0/eosio.cdt_1.7.0-1-ubuntu-18.04_amd64.deb $ sudo apt install ./eosio.cdt_1.7.0-1-ubuntu-18.04_amd64.deb
sudo apt remove eosio.cdt
$ wget https://github.com/eosio/eosio.cdt/releases/download/v1.7.0/eosio.cdt-1.7.0-1.el7.x86_64.rpm $ sudo yum install ./eosio.cdt-1.7.0-1.el7.x86_64.rpm
sudo yum remove eosio.cdt
git clone --recursive https://github.com/eosio/eosio.cdt cd eosio.cdt mkdir build cd build cmake .. make -j8
From here onward you can build your contracts code by simply exporting the
builddirectory to your path, so you don't have to install globally (makes things cleaner). Or you can install globally by running this command:
sudo make install
sudo rm -fr /usr/local/eosio.cdt sudo rm -fr /usr/local/lib/cmake/eosio.cdt sudo rm /usr/local/bin/eosio-*
Below tools are not installed after brew install, you get them only by building the repository and installing from scracth, see here eosio-abidiff eosio-ranlib eosio-ar eosio-objdump eosio-readelf
