[ptp-dev] Using PTP with MPICH2
|
Sorry to send this mail here other than user mailing list, but I have tried to find some help there while no solution was found.
Is there anyone who can help me?
I have run "sh BUILD", and I did not find the option -lmpi when I "man mpicc".
Thanks so much!
ps: When I tried to install RDT with CDT 5.0.2 from here : "
http://download.eclipse.org/tools/cdt/builds/5.0.2/I.I200809261507/index.html", which is the newest release version, I got dependency errors as follow:

So, I am wondering whether you have some different version which is still not released. If so, do you mind to share a copy with me?

Hi Zou,
I'm afraid I don't know why you get the error "Proxy disconnected". Did
you run "sh BUILD" in the directory
<eclipse_installation>/
plugins/org.eclipse.ptp.<os>.<arch>_2.1.0.YYYYMMDDHHMM
?
It creates an executable in
<eclipse_installation>/plugins/org.eclipse.ptp.mpich2_2.1.0.YYYYMMDDHHMM/bin
, and seems to be a necessary step.
The -lmpi is a compiler option which says "link with the file libmpi.a"
which is searched for in the directory given by the -L option (i.e.
/usr/local/lib in your case). however I don't see why you need these
options as the command mpicc is supposed to perform the link with the
mpi libraries automatically. So if you can compile without it then I'd
say that there's no need to worry.
As for the launching of MPICH2 without absolute paths, I haven't seen
this problem. For me it works fine. Though I have noted that behaviour
with MPICH1, which always requires a command line something like this;
mpirun -np 10 /absolute/path/to/executable/MPIHW
I'm afraid I can't help you much. I've more or less given up on trying
to get PTP to work. Which is a shame, as it looks like it could be very
useful.
Regards,
Steven
