"Ginette" is a free software project for GNU/Linux system. It was made in order to help the teenagers in solving equations and linear systems. "Ginette" read the equations from a text file which was written by the teacher. For each equation, the student have to choose between few operations in a combo-box. Theses operations will bring him gradually to the equation's solution. For example, to solve the equation "2x+3=-5x+4", the student can choose to substrac 3 from the two parts of the equation. The software's answer will be "2x=-5x+1" etc... This symbolic computation is based on the library "GINAC". The interface for the user is written with GTK-1.2. I use GTK rather GTKmm so as to make a version of "Ginette" for the MS-Windows system, but I need some help to use Ginac with MS Windows.
