seabiscuit at ubuntu:/$ ls /usr/local/lib

$ ls /usr/lib/grass/
bin  bwidget  docs  driver  etc  fonts  include  lib  man  scripts

But I think I fixed the problem now! :)

Here's the makefile :


prot1: utils.o db_mg.o session.o main.o
    gcc -o prot1 -L/usr/lib/grass/lib utils.o db_mg.o session.o
main.o-lreadline -lcurses -lgrass_gis -lm

main.o:
    gcc -c -I /usr/lib/grass/include -L/usr/lib/grass/lib main.c

session.o:
    gcc -c session.c


db_mg.o:
    gcc -c -I /usr/lib/grass/include db_mg.c


utils.o:
    gcc -c utils.c


clean:
    rm -f *.o *~ prot1

Thanks anyway for the help! :-D
