I'm trying to install the azimuth2.c add on (http://grass.osgeo.
org/wiki/GRASS_AddOns#Miscellaneous_Add-ons) on my grass6.4 running under
ubuntu 9.10
I'm really new to this kind of stuffs, so can you give me a little explanation
how about to compile and install this add on?
I had a look to this webpage http://grass.osgeo.
org/wiki/Compile_and_Install#Addons at the "compiled C modules" sections, but
this doesnt help me: mostly my C module doesn't come with a makefile, so i dont
know where to start.

It's not actually a GRASS module, it's just a little standalone C program.
compile it with:
$ gcc -lm azimuth2.c -o azumuth2
(-lm to link it to the math libary, for the trig functions)
then run it with:
$ ./azimuth2
note that v.to.db in grass 6.5svn and newer has support for uploading line
azimuth the the line attribute, but this is projection-dependent and I'm
not totally convinced that the numbers it gives are relevant outside of
a Mercator projection.
