Whenever the NAG C Library has been supplied in compiled form, that form is considered to be the standard library file. The use of all supplied software must be in accordance with the terms and conditions of the Software Licence signed by NAG and each site. Any request to use NAG software on a computer other than the one licensed must be referred to NAG (see Section 6).
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: IBM RISC System/6000 operating system: AIX 4.1 or compatible C compiler: XL C Compiler/6000 version 3.1 or compatible
For information about implementations of the NAG C Library for use on other computer systems please contact NAG.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: IBM RISC System/6000 Model 530H operating system: AIX 4.1 C compiler: XL C Compiler/6000 xlc, version 3.1.3.3 and its variant xlc_r compiler options: -O3 -qstrictThis implementation has also been tested under AIX 4.3 using XL C Compiler/6000 version 5.0.1.0.
The entire NAG C Library, Mark 6, was compiled with full optimization (-O3), except for the following functions which had to be compiled at lesser optimization levels:
g01fect.c (no optimization) g11bbf_ft.c (no optimization) x04fagt.c (-O2)
For further details, refer to other documentation supplied or contact NAG (see Section 6).

compiled archive libraries, libnagc.a: 7.8 Mb

compiled shareable libraries, libnagc_sh.a: 6.3 Mb
libnagc_ts_sh.a: 6.3 Mb

PDF documentation files: 30.5 Mb
To install all library material use the Unix tar utility, e.g.
tar xvf /cdrom/cl06.tar(assuming the CD-ROM has been mounted as /cdrom).
The archive libraries (libnagc.a and libnagc_ts.a) and the shareable libraries (libnagc_sh.a and libnagc_ts_sh.a) 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.
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 moved to a directory in the man search path, e.g.
cd doc mv nag_c_un.3 /usr/man/man3
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.
By default, the script nagexample uses libnagc.a (non-shareable, non-thread-safe version of the library), and the xlc variant of the XLC compiler. Users may choose to use any of the four supplied libraries, non-shareable or shareable, non-thread-safe or thread-safe. If a shareable version is to be used, the xlc_r variant of the XLC compiler should be used. The script nagexample may be modified as required, see the text of the script for further information.
The example programs for the undocumented routines f06pbc, f06sbc, f06ycc and f06zcc cannot be linked using the Shareable Library as a different version of the error handler is used in these tests. This does not affect the efficacy of these routines in normal usage.
The following material should also be made accessible to users:
compiled libraries:
libnagc.a libnagc_ts.a libnagc_sh.a libnagc_ts_sh.ainclude files:
include/*.hexample program material:
examples/source/??????e.c examples/data/??????e.d examples/results/??????e.r scripts/nagexamplelibrary documentation files:
doc/callspdf documentation files
Note that the example material has been adapted, if necessary, from that printed in the NAG C Library Manual, so that programs are suitable for execution with this implementation with no further changes. Making the example material directly available to users provides them with easily adaptable templates for their own problems.
On-line documentation is provided, in PDF form, with this implementation. Further information is contained in the Readme file on the distribution medium.
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 please quote your NAG site reference and NAG product code (in this case CLIB606DA).
The NAG websites are an information service providing items of interest to users and prospective users of NAG products and services. The information is reviewed and updated regularly and includes implementation availability, descriptions of products, downloadable software, product documentation and technical reports.
