EOSIO.CDT (Contract Development Toolkit)
Version : 1.8.1
EOSIO.CDT is a toolchain for WebAssembly (WASM) and a 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 9, 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.
- Please see the Upgrading Guide 1.2 to 1.3 and Upgrading Guide 1.5 to 1.6 to be aware of any breaking changes.
- There is currently a known issue that a minimum of 2 CPU cores is required for using EOSIO.CDT
EOSIO.CDT currently supports Mac OS X brew, Linux x86_64 Debian packages, and Linux x86_64 RPM packages.
If you have previously installed EOSIO.CDT, run the
uninstall script (it is in the directory where you cloned EOSIO.CDT) before downloading and using the binary releases.
Mac OS X Brew Install
brew tap eosio/eosio.cdt brew install eosio.cdt
Mac OS X Brew Uninstall
brew remove eosio.cdt
Debian Package Install

Guided Installation or Building from Scratch
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
build directory 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
Uninstall after manual installation
sudo rm -fr /usr/local/eosio.cdt sudo rm -fr /usr/local/lib/cmake/eosio.cdt sudo rm /usr/local/bin/eosio-*
