Your attention is drawn to the terms and conditions of the Software Licence regarding the use of NAG software. Any request to use this software other than on the licensed computer must be referred to NAG, as should requests for information about the availability of other implementations.
This implementation is a compiled, tested, ready-to-use version of the NAG C Library that is considered suitable for operation on the computer systems detailed below:
hardware: Intel 64-bit systems operating system: Linux 2.4.21-9 (Red Hat Enterprise Linux 3.0) or compatible C compiler: gcc version 3.2.3 or compatible
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: Intel Itanium operating system: Linux 2.4.21-9 (RHEL 3 (Taroon Update 1)) C compiler: gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-24) compiler options: -fPIC -D_REENTRANT -fexceptions
The entire NAG C Library, Mark 7, was compiled with full optimization

This Library has been tested with the Basic Linear Algebra Subprograms (BLAS) and linear algebra functions (LAPACK) provided by NAG (see the Chapter Introductions for f06, f07 and f08 in the NAG C Library Manual) and not with BLAS/LAPACK routines from other sources.

compiled libraries: libnagc.a: 27.0 Mb libnagc.so.7: 17.7 Mb include files: 1.2 Mb example program material: 4.2 Mb library documentation files: 0.1 Mb scripts: 0.1 Mb PDF documentation files: 87 Mb licensing materials 53.8 Mb
To install all material use the Unix tar utility, e.g.
tar xvf /cdrom/cl07.tar(assuming the CD-ROM has been mounted as /cdrom).
The static and dynamic (shareable) versions of the NAG C library are functionally equivalent. Sites should determine whether they prefer one type of library to the other. The advantages (briefly) of using the static library are:
After taking the above remarks into consideration, you may decide to delete one of the libraries.
One or both of the object libraries (libnagc.a, libnagc.so.7) 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 library (libnagc.so.7) then, once the library is in place, a symbolic link should be made to point to it:
ln -s libnagc.so.7 libnagc.so
The include files should be moved to a directory such as /usr/include so that they can be accessed during compilation, e.g.
mv include/*.h /usr/include
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_c_un.3 /usr/local/man/man3
In order to enable the software, NAG will issue you with a license key. The license key is a simple text file (usually called license.dat), containing details of the software that will be enabled.
To request a license key, locate and run the program key_rqst in the appropriate platform specific subdirectory under the license/bin/ subdirectory of the software distribution. This utility does not have a GUI and must be run from a command prompt. Complete the form that it displays and e-mail (or FAX) it to NAG.
A short term (demonstration or trial) license key contains one or more lines like the following:
FEATURE NAG_CL NAG 7.000 10-apr-2002 0 CBDA2041DC1BC45D2B68 "ANY" DEMOSpecifically, it does not have any lines starting with the word SERVER and is referred to here as an uncounted license key. Longer term uncounted license keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These license keys include the FLEXlm hostid of the computer instead of the word DEMO above.
Once you have obtained the license key, store the text of it in a file, say /opt/nag/license.lic.
If the license file contains one or more SERVER lines, the FLEXlm daemons must be started before you can use the license. Refer to the FLEXlm End Users Guide supplied in the license/htmlman/flexuser/ subdirectory (start at the file TOC.htm).
For an uncounted license, the location of the license file must be made known to the NAG application by setting the environment variable LM_LICENSE_FILE to the full pathname of the file before the application is invoked.
For example, in the C-shell, type:
setenv LM_LICENSE_FILE /opt/nag/license.licor in the Bourne shell, type:
LM_LICENSE_FILE=/opt/nag/license.lic export LM_LICENSE_FILENo other actions are required to install an uncounted license.
Further details about FLEXlm and how it may be configured to suit your local circumstances are included in the FLEXlm End Users Guide.
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.
If you do not already have a copy of Adobe Acrobat Reader for your platform, a free copy can be downloaded from http://www.adobe.com/. Please check this site for availability of a reader for your platform.
Please note that if you are using Adobe Acrobat 4.0 or earlier you might experience some problems when printing documents that contain non-standard characters, such as integral signs, square roots and large brackets. These characters will print correctly using Adobe Acrobat 5.0.
The HTML form of the Essential Introduction contains some mathematical characters that are displayed as question marks by older browers such as pre-version 6 Netscape. However these are displayed correctly by recent browsers including Internet Explorer. They may also be viewed via the PDF.
If using Netscape, it might be necessary to re-install Acrobat to ensure that the Acrobat plug-in has been installed. If the plug-in has not been installed, Netscape may copy PDF files to a temporary directory, and then not be able to navigate from there.
The following material should also be made accessible to users:
the NAGdoc directory contains the online documentation.
One or more of the compiled libraries:
libnagc.a libnagc.so (symbolic link pointing to libnagc.so.7)Include files:
include/*.hExample program material:
examples/source/??????e.c 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 C Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.4 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 functions 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.
Online 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 CLL6407DAL).
