[Fauzi]

Dear all,

I'm very newbie in parallel computing. I'm using Freebsd with mpi. I have 
problem when execute (./mpicc) my program. My program using math.h. When I execute there comment :

#./mpicc -o lat lat.c
lat.o : In function 'main'
lat.o(.text+0x51) : undefined reference to 'sin'

What happen with mpi? what is solution? Anybody can help me, please?

I'm sorry if my question so easy for you.
