<br>
$ ls /usr/lib/grass/<br>
bin bwidget docs driver etc fonts include lib man scripts<br>
<br>
But I think I fixed the problem now! :)<br>
<br>
Here's the makefile : <br>
<br>
<br>
prot1: utils.o db_mg.o session.o main.o<br>
gcc -o prot1 -L/usr/lib/grass/lib utils.o db_mg.o session.o main.o -lreadline -lcurses -lgrass_gis -lm<br>
<br>
main.o: <br>
gcc -c -I /usr/lib/grass/include -L/usr/lib/grass/lib main.c<br>
<br>
session.o: <br>
gcc -c session.c<br>
<br>
<br>
db_mg.o:<br>
gcc -c -I /usr/lib/grass/include db_mg.c<br>
<br>
<br>
utils.o:<br>
gcc -c utils.c<br>
<br>
<br>
clean: <br>
rm -f *.o *~ prot1<br>
<br>
Thanks anyway for the help! :-D<br>

<br>Yoy forgot again the -L/usr/local/grass6/lib switch in the linking<br>command (you have all the GRASS libs there, haven't you?).<br><br>Anyway, the easiest way to start programming against theses libraries<br>is reusing the code in grass6/vector/v.sample directory, in GRASS
<br>sourcecode. Rename your code as "main.c" and run "make" to compile.<br>Unfortunately the Makefile file assumes that you managed to compile<br>and build GRASS, not a trivial task (nor too dificult).
