pyvxl

Python wrapper for vxl using pybind11

Requirements

• pybind11 - You need to add the pybind11 repo as a submodule to your project (or install it into the OS)
• vxl

Cmake

pyvxl can be build standalone or as a module of an existing project.

Standalone

Whatever environment (your host or a docker container) you build pyvxl in will require these dependencies

• g++
• Python 3 development libraries (e.g. python3-devel)
• GeoTIFF development libraries (e.g. libgeotiff-devel)
• CMake
• Ninja (optional)

If you're not using ninja, replace "ninja" in the commands below with "make".

Using a virtualenv (recommended)

To avoid messing with your host machine, you can build pyvxl in a virtualenv

virtualenv -p python3 env
source env/bin/activate
mkdir build && cd build
cmake -DVXL_DIR=${VXL_DIR} -DPYBIND11_DIR=${PYBIND11_DIR} -G Ninja -DPYTHON_SITE=${YOUR_VIRTUALENV_SITE-PACKAGES} ..
ninja
ninja install

Not using virtualenv

If you're not going to use a virtualenv because you're in a docker, or your host machine (not recommended), then you can drop the PYTHON_SITE variable

mkdir build && cd build
cmake -DVXL_DIR=${VXL_DIR} -DPYBIND11_DIR=${PYBIND11_DIR} -G Ninja ..
ninja
ninja install

Test your build

python3 -c "import vxl"

As part of your project

In your CMake file, just add

find_package(PythonLibs 3 REQUIRED)
add_subdirectory(${Your pybind11 dir})
add_subdirectory(${Your pyvxl dir})
