This is a continuation of the following thread:
http://www.lam-mpi.org/MailArchives/lam/msg06206.php
You (Jeff 'you Da MAN!' Squyres) mentioned several useful things
for one, 'mpicc -showme' shows the libraries linked too when compiling mpi
apps:
gcc -llammpio -lpmpi -llamf77mpi -lmpi -llam -lutil
HOWEVER, when i try and run gcc as similarly to what is shown above:
gcc -lpmpi -llamf77mpi -lmpi -llam -lutil -o n mpicode.c
shown above, i get errors like :
/tmp/ccPQeQ3l.o(.text+0x19): undefined reference to `MPI_Init'
and more like that. running 'mpicc -o n mpicode.c' works just fine.
what gives?
btw, the command to extract, list or add object files (.o files) files to
library files (.a files) is 'ar'. and i am still using lam 6.5.9.
