This implementation is a compiled, tested, ready-to-use version of the NAG Fortran Library that is considered suitable for operation on the computer systems detailed below:
hardware: all SPARC Ultra systems operating system: Solaris 7 and 8 or compatible Fortran compiler: Sun Forte (Workshop 6, f77, f90, f95) and compatibleThis implementation is not suitable for creating multi-threaded applications: a separate implementation, FLSO620DT, is available for that purpose.
Note that, except for the two routines X04ACF and X04ADF, the libraries in this
implementation are compatible with Sun Fortran 90/95, provided that the f90/95
compiler is called with the flag
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: Sun UltraSPARC-5_10 and also tested using a Sun UltraSPARC-80
operating system: Solaris 8 (SunOS 5.8) and also tested using Solaris 7
Fortran compiler: Sun WorkShop 6 update 1 FORTRAN 77 5.2. Also tested using:
Sun WorkShop 6 update 1 Fortran 95 6.1 Patch 109503-05
(f90 is a link to f95)
Sun WorkShop 6 update 2 FORTRAN 77 5.3
Sun WorkShop 6 update 2 Fortran 95 6.2
compiler options: -dalign -xtarget=generic64 -PIC
-fsimple=1 -libmil -xlibmopt -depend -xprefetch=yes
The entire NAG Fortran Library, Mark 20, was compiled with the above compiler
options and

The libnag.a and libnag.so.20 object libraries have been tested using the Basic
Linear Algebra Subprograms (BLAS) and linear algebra routines (LAPACK) provided
by NAG (see the Chapter Introductions for F06, F07 and F08 in the NAG Fortran
Library Manual). The

To install all material use the Unix tar utility, e.g.
tar xvf /cdrom/fl20.tar(assuming the CD-ROM has been mounted as /cdrom).
A site may not need to install all four of the object libraries provided in this distribution. After installing all material as described above, you may wish to delete some material if it is not required.
To decide which is the most suitable object library for your site, determine:
After taking the above remarks into consideration, you may decide to delete some of the libraries.
The object libraries (libnag.a, libnag.so.20, etc.) should be moved to a directory, such as /usr/lib, in the default search path of the linker, if possible, so that linkage is convenient. If you decided to install the shareable versions of the libraries, then once the libraries are in place symbolic links should be made to point to the shareable libraries, e.g.
ln -s libnag.so.20 libnag.so ln -s libnag-spl.so.20 libnag-spl.soUnless this is done, the linker, ld, will not be able to find the shareable libraries.
If you do not wish to move the libraries to a system directory, you may use
the
The script nagexample refers to the local directory containing the example programs. The file should be copied to (for example) /usr/local/bin, modified to reflect the local installation, and its protection set to world execute.
The man page, which directs users to the HTML form of the Users' Note, should be modified to reflect the local installation, and moved to a directory in the man search path, e.g.
cd doc mv nag_fl_un.3 /usr/local/man/man3The NAG Fortran Library Interface Blocks define the type and arguments of each user callable NAG Fortran Library routine. These are not essential to calling the NAG Fortran Library from Fortran 90/95 programs. Their purpose is to allow the Fortran 90/95 compiler to check that NAG Fortran Library routines are called correctly.
The interface block files (interface_blocks/*.mod) are supplied in pre-compiled module form. They should be moved to a suitable location so that access is convenient, e.g.
mkdir /usr/local/lib/fl77_modules mv interface_blocks/* /usr/local/lib/fl77_modules

tar xvf /cdrom/pdf.tar(assuming the CD-ROM has been mounted as /cdrom).
You may wish to move the PDF documentation files to the same location as that for other NAG products. You are encouraged to make them readily available to users, but in such a way that they are not generally accessible from outside your site. Further information is contained in the readme file on the distribution medium.
The following material should also be made accessible to users:
documentation files:
The NAGdoc directory contains the online documentation. This should be made available to users, in addition to the following:
doc/blas_lapack_to_nag doc/nag_to_blas_lapackone or more of the compiled libraries:
libnag.a libnag.so (symbolic link pointing at libnag.so.20) libnag-spl.a libnag-spl.so (symbolic link pointing at libnag-spl.so.20)interface block files:

examples/source/??????e.f examples/data/??????e.d examples/results/??????e.r scripts/nagexample
Note that the example material has been adapted, if necessary, from that published in the NAG Fortran Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.4.2 for comments about possible differences in results obtained). Making the example material directly available to users provides them with easily adaptable templates for their own problems.
The "example programs" for the routines in the F06 chapter are not typical example programs and they are not in the Library Manual. They are test programs, which are supplied to sites for use in an installation test of the Library. Some of them take much longer to run than other example programs. Routines which are equivalent to BLAS, are tested twice: once when called by their NAG F06 names, and once when called by their BLAS names.
On-line documentation is bundled with this implementation. Please see Section 4.2.
The NAG Response Centres are available for general enquiries from all users and also for technical queries from sites with an annually licensed product or support service.
The Response Centres are open during office hours, but contact is possible by fax, email and phone (answering machine) at all times.
When contacting a Response Centre it helps us deal with your enquiry quickly if you can quote your NAG site reference and NAG product code (in this case FLSO620DA).
