Hi -
I've got the following compile line using the Portland Group (PGI) f77
compiler
pgf77 -byteswapio -r8 -c write_state.f
I'm trying to figure out a corresponding line for the Sun Studio
compiler...I thought the following would work
sunf95 -xfilebyteorder=big16:%all -r8const
The code compiles but chokes when trying to read an existing binary file
that contains 64-bit binary numbers (I'm working with the MITgcm code if
that makes a difference - I don't know how the binary file was created, but
it is read just fine when I compile with the PGI compiler).
>From the pgf77 manual:
-byteswapio: Swap bytes from big-endian to little-endian or vice versa on
input/output of unformatted Fortran data. Use of this option enables
reading/writing of Fortran unformatted data files
compatible with those produced on Sun or SGI systems.
-r8: Interpret REAL variables as DOUBLE PRECISION.
I'm working on a Linux x86-64 system... when I compile the code with the PGI
compiler, all is well. When I use the Sun Studio compiler, the code chokes
when trying to read the binary file.
