Re: [bgl-discuss] MPI link problems

[Sameer Shende <sameer@xxxxxxxxxxxxxx>]

Hi,
	Would you:

1) Recompile all your .o files with either blrts_xlf90 (for Fortran) or
blrts_xlC (for C++) (instead of using xlc++ and xlf90),
2) Remove the -lnsl from your link line, and
3) Try using:
blrts_xlC *.o -L<dir> -l<yourlibs>
-L/soft/tools/tau/tau-2.14.8/bgl/lib
-lTauMpi-mpi-pdt -L/bgl/BlueLight/ppcfloor/bglsys/lib -lmpich.rts
-lmsglayer.rts -ldevices.rts -lrts.rts -ldevices.rts
-L/soft/tools/tau/tau-2.14.8/bgl/lib -ltau-mpi-pdt
-L/opt/ibmcmp/xlf/9.1/bin/../blrts_dev_lib
-L/opt/ibmcmp/xlf/9.1/bin/../blrts_lib -lxlf90 -lxlfmath -lxl   -lm

I'd avoid adding .o and -l files at the end (putting them instead at the
beginning), and send us the errors obtained after linking this way.

	Thanks,
	- Sameer

To add or remove yourself from this mailing list, use the 'notifyme'
command on any BGL machine. To remove: notifyme -n, to add: notifyme -y.
