Exporting Ada Software to Python and Julia

The objective is to demonstrate the making of Ada software available to Python and Julia programmers us-ing GPRbuild. GPRbuild is the project manager of the GNAT toolchain. With GPRbuild the making of shared object files is fully automated and the software can be readily used in Python and Julia. The application is the build process of PHCpack, a free and open source software package to solve polynomial systems by homotopy continuation methods, written mainly in Ada, with components in C++, available at github at https://github.com/janverschelde/PHCpack.
