Well first let me say I have no clue about doing anything on my server, I ask my host to do all installs for me.

I run a website where users store latitude and longitude coordinates in my database. I would like them to be able to download these waypoints to their gps units.

I found a program called GPSBabel that allows this to be done. http://www.gpsbabel.org/

I want to be able to control GPSBabel from PHP using exec() or something along those lines.

The problem is that the linux version of the program is a source file and they don't want to build or install it without some source of instructions. Does anyone have experience with installing this? Perhaps know someone that has and that can lead me in the right direction?

Any help would be hugely appreciated. I'm pretty much stuck without getting this to work.
