Installation

This page describes common build and installation paths for EWTS.

Requirements

EWTS typically requires:

  • CMake 3.16 or newer
  • a C/C++ compiler
  • a Fortran compiler when building the Fortran runtime
  • Python 3 for the Python runtime and generator tooling

Build the full repository

cmake -B cmake_buld -S . -DCMAKE_BUILD_TYPE=Release -DEWTS_WITH_NGEN=ON -DEWTS_BUILD_SHARED=ON
cmake --build cmake_buld -j

This top-level build compiles the native language-specific Runtime Libraries and builds the Python package.

Install

cmake --install cmake_buld --prefix /path/to/install

A typical install includes:

  • native EWTS Runtime Libraries
  • generated constants and headers
  • the ngen integration library when enabled
  • CMake package configuration files
  • the Python wheel produced by the top-level build

Build Runtime Libraries only

cmake -B cmake_buld -S runtime -DCMAKE_BUILD_TYPE=Release
cmake --build cmake_buld -j

Editable Python install

For direct Python runtime development:

pip install -e runtime/python/ewts

Build a Python distribution manually

python -m build runtime/python/ewts

Run Python tests

pip install pytest
pip install -e runtime/python/ewts

pytest runtime/python/ewts/tests

or

pytest
