is there a searchable archive of this mailing list?
I am helping someone use Openmpi with Sun's compilers that came with
SolarisStudio. I used the --showme with mpif90 and got this
gfortran -I/opt/openmpi/include -pthread -I/opt/openmpi/lib
ring_f90.f90 -L/opt/openmpi/lib -lmpi_f90 -lmpi_f77 -lmpi -lopen-rte
-lopen-pal -ldl -Wl,--export-dynamic -lnsl -lutil -lm -ldl
that line compiles fine and so does the mpif90 command but when I
replace gfortran with sunf90 or the absoulute path to my solaris
studio compilers I get this
$ f90 -I/opt/openmpi/include -pthread -I/opt/openmpi/lib ring_f90.f90
-L/opt/openmpi/lib -lmpi_f90 -lmpi_f77 -lmpi -lopen-rte -lopen-pal
-ldl -Wl,--export-dynamic -lnsl -lutil -lm -ldl
f90: Warning: Option -pthread passed to ld, if ld is invoked, ignored
otherwise

Now, i must warn you, I don't know FORTRAN but I am supporting someone
who does. I have them CC
