macOS Installation (macOS 13)

Prerequisites

Install system tools:

brew update
brew install ninja autoconf automake autoconf-archive pkg-config vtk

Clone Repository

git clone --recurse-submodules https://github.com/<your-org>/SPHinXsim.git
cd SPHinXsim

Install vcpkg

git clone https://github.com/microsoft/vcpkg.git ../vcpkg
../vcpkg/bootstrap-vcpkg.sh

Install C/C++ Dependencies

../vcpkg/vcpkg install --clean-after-build openblas[dynamic-arch] --allow-unsupported
../vcpkg/vcpkg install --clean-after-build \
  eigen3 \
  tbb \
  boost-program-options \
  boost-geometry \
  simbody \
  spdlog \
  gtest \
  pybind11 \
  nlohmann-json

Configure and Build

For a pip-first workflow, install directly from source (this builds C++ extensions via CMake):

CMAKE_ARGS="-D CMAKE_TOOLCHAIN_FILE=$(pwd)/../vcpkg/scripts/buildsystems/vcpkg.cmake" \
python3 -m pip install -e ".[dev,visualization]"

Optional manual CMake workflow:

cmake --preset integrated-build-release \
  -D CMAKE_TOOLCHAIN_FILE="$(pwd)/../vcpkg/scripts/buildsystems/vcpkg.cmake" \
  -D Python3_EXECUTABLE="$(which python3)"
cmake --build --preset integrated-build-release --parallel "$(sysctl -n hw.logicalcpu)"

Install compiled C++ extension modules into the active Python environment:

cmake --install build-integrated --prefix "$(python3 -c 'import sys; print(sys.prefix)')"

Run Tests

Install Python package with dev dependencies:

python -m pip install -e ".[dev]"

To enable geometry preview (sphinxsim preview), also install:

python -m pip install -e ".[visualization]"

Run Python tests:

python -m pytest tests/ examples/ -v

Run C++ simulation tests:

ctest --test-dir build-integrated --output-on-failure -R "test_(2d|3d)_simulation$"
