dumpbin of interface routine - linking HDF

[scrognoid]

Should "dumpbin -symbols hdf4interfaces.obj" show me the aliases I am trying to create into HDF. hdf4interfaces.f90 looks like this:

module hdf4interface
interface
function dfsdsetdims [C,ALIAS:'_DFSDsetdims'](rank,dim_sizes)
integer*4 dfsdsetdims,rank,dim_sizes(*)
end function
end interface
end module


dumpbin produces:
Dump of file hdf4interface.obj

File Type: COFF OBJECT

I don't see the external symbols that I'm missing when I link.

No. An interface block does not correspond to any object code. I would also recommend that you switch from the old Microsoft Fortran PowerStation square bracket syntax for attributes to the Fortran 2003 BIND(C,NAME=). Note that you would leave off the leading underscore when doing this.
