I am busy installing Gtk ada version 3.24 the latest version I can download from Git.Hub. I think I finally almost succeeded but: I see in Gtkshared-shared.gpr.in the following :
@BUILD_TYPE@ , @NEED_OBJECTIVE_C@ , @DEFAULT_LIBRARY_TYPE@ , @SO_EXT@ ,
@PACKAGE_VERSION@ , @GTK_CFLAGS_GPR@ , @GTK_LIBS_GPR@ , @OBJC@ ,
I don’t know how to Fill them correctly
