The Makefile for this package assumes that your libraries are in some sort of standard places. By default GTK+ installs itself in /usr/local/lib, whereas I forced it to install into /usr/lib on my system. This should not be a problem. To build mtrack, type: make and then: make install This will install the mtrack program into /usr/bin, the maps and help files into /usr/share/mtrack, the data files into /var/mtrack, and the system wide configuration file into /etc. The path of the these files is hard coded into the program, so if you decide to install it elsewhere then you will need to modify the mtrack.c and rebuild the programs. You can make mtrack look elsewhere for its data files by setting the environment varaible MTRACK_PATH, this will override the built-in default path. If you already have mtrack installed, you can choose to install only parts of the package. By default "make install" will install everything, but using "make install-progs" will install the programs, "make install-data" will install the satellite data, location data and the default user profile data, "make install-maps" will install the maps, and "make install-help" will install the help files. Typing "make clean" will purge the mtrack distribution of unwanted crud. "make uninstall" will delete the mtrack program and all its data files. Jonathan Naylor HB9DRD/G4KLX
