NAG Fortran Compiler Release 5.3

                 Technical Information Note (TECHINFO)

1. Introduction

The following implementations of the NAG Fortran Compiler Release 5.3 are
available on CDROM or by download from the NAG web site.

Product code    Target platform                     Distribution directory
------------    ---------------                     ----------------------
NPL6A53NA       x86-64 Linux (AMD64 or EM64T)       NAG_Fortran-amd64
NPLUX53NA       x86 Linux                           NAG_Fortran-rh90
NPMI653NA       Apple Intel Mac OS X 64 bit         NAG_Fortran-macx64


2. Installation for unix

(1) From CDROM:
    Connect to the distribution directory on the CD and type CDINSTALL.
    E.g.
        cd /cdrom/NAG_Fortran-amd64
        ./CDINSTALL

(2) From an internet distribution:
    Unpack the gzipped tar file into an area with sufficient space.
    install as per the CD distribution, e.g.
    Connect to the distribution directory and type INSTALL.
    E.g.
        gunzip NAG_Fortran-amd64.tgz
        tar xf NAG_Fortran-amd64.tar
        cd NAG_Fortran-amd64
        ./INSTALL

(3) To run directly from CDROM or an unpacked tar distribution:
    Connect to the distribution directory and type CDRUN.
    E.g.
        cd /cdrom/NAG_Fortran-amd64
        ./CDRUN

3. Machine-specific Details

Details of the product specific to each machine are given below.  The
products were tested on the specified operating system version and so
should work on fully compatible later releases of the operating
system. Details are also given as to whether the runtime garbage
collector is supported and whether 128-bit reals are supported. Which
debugger is used and any restrictions have also been documented.

NPL6A53NA - AMD64/EM64T Linux glibc2.4 or compatible
----------------------------------------------
Machine: AMD x86_64 (Opteron) or Intel EM64T (Xeon)
Operating System: Kernel version  2.6.16.46 or compatible
glibc: 2.4.x or compatible
C Compiler: gcc 4.1.2 or compatible
Space Required: 49 MB
Garbage Collection: Yes
128-bit reals: Yes
Debugger: dbx90
Licence management: Kusari 2.2
Note: This implementation supports object sizes greater than 2 GB.
      The default ABI of this version is incompatible with
      previous releases.  In order to generate code compatible
      with 5.1(346) or earlier, please use the -abi=64 option.
      (The -abi=64 option will be withdrawn in a future release
      of NAG Fortran.)  In order to run dynamic executables
      linked with 5.1(346) or earlier, the environment variable 
      LD_LIBRARY_PATH must be set to ensure the compatible shareable
      library is picked up from the subdirectory x86_64f of the
      compiler lib directory, default /usr/local/lib/NAG_Fortran/x86_64f.
