hi, I was able ti link a programm whith other functions by creating a static library thanks to the terminal(thx mezek for your tutorial 
). Now this programm is debugged, I would like to be able to call it by simply clicking on a widget under PhAB. I tried to link this programm to the widget and to copy all the related functions(.c, .o and .h) in the interface’s folder, but it didn’t work 
,as it didn’t link to the functions. So is there a way to call the executable which works in a new programm ? How should I proceed?
thx
system()
