CDT Release with Python Wheel Package

EOSCDT

Installation

Linux & MacOS X

python3 -m pip install -U eoscdt
eoscdt check

Windows

python -m pip install -U eoscdt
eoscdt check

Quick start

cdt-init --project hello
cd hello
mkdir build
cd build
cmake -Dcdt_DIR=`cdt-get-dir` -G"Unix Makefiles" ..
make -j$(nproc)

If everything goes well, you will find hello.wasm and hello.abi in your build/hello directory.

About Windows

Setup MSYS2 Development Environment

It's recommended to use msys2 as a build environment. After installation, click start button on the Windows taskbar, search for msys2 clang64 and open it. Then run the following command to install dependencies.

pacman --noconfirm -S git
pacman --noconfirm -S --needed base-devel mingw-w64-clang-x86_64-clang
pacman --noconfirm -S mingw-w64-clang-x86_64-gdb mingw-w64-clang-x86_64-compiler-rt
pacman --noconfirm -S mingw-w64-clang-x86_64-boost
pacman --noconfirm -S mingw-w64-clang-x86_64-cmake
pacman --noconfirm -S mingw-w64-clang-x86_64-python
pacman --noconfirm -S mingw-w64-clang-x86_64-python-pip

Finally, install eoscdt

python -m pip install -U eoscdt
eoscdt check

If you are using Visual Studio Code as an IDE, you can use msys2 bash as your terminal. search for Preferences: Open User Settings(JSON) and open it. Add the following configuration for msys2

"terminal.integrated.env.windows": {
    "MSYSTEM": "CLANG64",
    "CHERE_INVOKING": "1",
    "MSYS2_PATH_TYPE": "inherit",
    "LIBRARY_PATH": "/clang64/lib"
},
"terminal.integrated.profiles.windows": {
    "msys2": {
        "path": "G:\\msys64\\usr\\bin\\bash.exe",
        "args": ["--login", "-i"]
    }
}

Change G:\\msys64\\usr\\bin\\bash.exe to the location of bash.exe you installed.

For more details, please see Terminal Profiles

Official Python Development Environment

If you have downloaded and installed python from official python website, don't forget to enable Add Python to environment variables option during the installation, otherwise cmd.exe will have problem finding executable programs of CDT.

Launch cmd.exe to install eoscdt, cmake and ninja

pip install -U eoscdt
eoscdt check
pip install cmake
pip install ninja

Also you need to change project(xxx) to project(xxx NONE) in your CMakeLists.txt to pass the compiler checking if you didn't install other compiler such as Visual Studio on your Windows.

Here is a minimal steps about building smart contracts with only cmake and ninja installed

cdt-init --project hello

add project(hello NONE) to CMakeLists.txt

get the cdt directory

cdt-get-dir
