Re: shared lib can't be loaded

Hi Leilei,

A caveat: I have some familiarity with the Lahey Fortran compiler,
though not on the same configuration on which you're running. The
version of Lahey's compiler I've worked with is v6.2.

There is a routine in the Lahey-supplied libraries called g_arxr -- I
found it in the following libraries:

     libfj9f6.a
     libfj9fpp.a
     libfj9fsse2.a
     libfj9fsse2p.a
     liblapackmt.a
     libssl2.a
     libssl2mt.a
     libssl2mtp4.a

I can't say with any certainty which library defines the routine. You
may have to experiment to determine which you really need. I believe
you'll need to compile your Fortran routine (below) with one or more of
these libraries.
