Information for developers¶

In case you are willing to contribute to Codac, here are some information that may be useful.

Definition

CMake supports the following options for development:

Option	Description
CMAKE_INSTALL_PREFIX	See more
CMAKE_BUILD_TYPE	See more
CMAKE_PREFIX_PATH	See more
WITH_CAPD=ON	See more (not fully supported yet)
BUILD_TESTS	By default, the tests are not built. To enable the compilation of tests: cmake <other_cmake_options> -DBUILD_TESTS=ON ..
TEST_EXAMPLES	This will add the execution of the examples in the tests list. cmake <other_cmake_options> -DTEST_EXAMPLES=ON ..
WITH_PYTHON	Note: you need to have `doxygen` and Python3 installed on your computer. To enable the compilation of Python binding: cmake <other_cmake_options> -DWITH_PYTHON=ON -DCMAKE_CXX_FLAGS="-fPIC" -DCMAKE_C_FLAGS="-fPIC" .. This configuration generates header files containing docstrings for Python, based on the content of XML files made by Doxygen. The documentation of any C++/Python function is then located in the C++ header files of the `/src` directory.

Tips

To speed up the compilation with make and take benefit of, for example, 4 cores of your processor, use the -j option:

cd build
make -j4

Tests

Launch the tests:

cd build
make test

User manual

Build this user manual using Sphinx:

# Install Sphinx with
pip3 install -U sphinx breathe sphinx_rtd_theme sphinx-tabs sphinx-issues sphinx-reredirects

# Build the doc
cd build
make doc

The website will be generated in build/doc/.

API technical documentation

For building the API technical documentation using Doxygen:

# Install Doxygen with
sudo apt install doxygen graphviz

The API pages will be generated in build/doc/api/html/.

Script make.sh

One shortcut to build all the examples (including 3rd parties) is given by:

# From Codac root
./make.sh examples

Note that the build folders of each example is removed before the build.

One shortcut to build the tests is given by:

# From Codac root
./make.sh tests

One shortcut to build both the examples and tests is:

# From Codac root
./make.sh all

Visualization of graphs of CN

sudo apt install dot2tex

Install IBEX for Python binding (example of local install)

cmake -DCMAKE_CXX_FLAGS="-fPIC" -DCMAKE_C_FLAGS="-fPIC" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=$HOME/ibex-lib/build_install ..

IBEX uses the GAOL library by default, but Filib++ is also supported. Use -DINTERVAL_LIB=filib during the CMake configuration to use it.

Installing local Python binding

Warning

The binding is not working with G++7 for the moment.

Get Pybind11 as submodule:

git submodule init
git submodule update

Then, configure cmake with your custom options <...> and -DWITH_PYTHON=ON:

cmake <...> -DWITH_PYTHON=ON -DCMAKE_CXX_FLAGS="-fPIC" -DCMAKE_C_FLAGS="-fPIC" ..

This configuration generates header files containing docstrings for Python, based on the content of XML files made by Doxygen. The documentation of any C++/Python function is then located in the C++ header files of the /src directory.

Note that you also have to configure IBEX with the -DCMAKE_CXX_FLAGS="-fPIC" flag.

Finally, after the compilation of Codac (and IBEX):

# from codac repository
cd build/python/python_package
python3 setup.py develop --user

Script to create a first draft of binding

Copy the pybind11gen.py script in the sources folder. Then, for instance:

python3 pybind11gen.py module_name=RandTrajectory codac_RandTrajectory.h
# get the files in /tmp

[For admins] Upload Python binding on PyPi (see Codac repo)

Tag the current version:

git tag -a v3.0.0-beta1
git push origin v3.0.0-beta1

Create the wheels with a Docker:

docker pull benensta/pyibex-docker
docker run --rm -v `pwd`:/io benensta/pyibex-docker /io/scripts/docker/build_pybinding.sh

Upload the wheels on PyPi:

python3 -m twine upload --repository pypi *

Testing with Docker

In the codac directory, test the Ubuntu configuration locally using Docker:

chmod a+x scripts/docker/build_pybinding.sh
docker run --rm -v `pwd`:/io lebarsfa/manylinux2010_x86_64-for-codac /io/scripts/docker/build_pybinding.sh
