I assume you meant

  ierr = nf_open(filen,NF_NOWRITE,ides)

If you're getting a bus error while opening the file, how can the
subsequent print statement print anything?  Do you mean you're getting
a bus error later, when using "ides"?

Is "ides" declared to be an INTEGER?  If ierr is returned as zero,
ides should be returned as a small integer, such as 11.

I don't know what the "-N15" or "-N90" flags mean.  I assume "f77" is
the Absoft Fortran compiler.  Did the "make test" work OK in the
src/nf_test directory with this compiler?  If so, you might want to look
at the compiler flags used in that test, since it calls "nf_open"
several times.  If you are using different Fortran compiler flags than
were used in building the netCDF library, that might cause problems.
