  The objective is to demonstrate the making of Ada software available to
Python and Julia programmers using 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.
