The NAG AD Library is not included in this implementation.
The definitions and sizes of the C Integer and Pointer types used in this implementation are shown in Section 3.5 of the Users' Note.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:

Details of the software are given in the Users' Note (un.html).
If you have downloaded the Library materials, double click on nlmi627dgl.dmg to mount the disk image. You should see the files install.command, nl27.tgz, nag_tsandcs.txt, in.html, un.html and mk27_doc.tgz.
To install the Library software, double click on install.command and follow the instructions. By default, the materials will be installed under $HOME/NAG/, or if the directory $HOME does not exist, under /opt/NAG/. However, you may choose a different location. In this document we refer to the directory $HOME/NAG/nlmi627dgl or /opt/NAG/nlmi627dgl as [INSTALL_DIR]. This convention is also used in the Users' Note.
The install script can install the Library Manual in the
same location as the NAG Library material or at some other location of
your choice.
Alternatively, the Library Manual may be viewed from the NAG website
In order to enable the software, NAG will issue you with a licence key as follows. The licence key is contained in a text file consisting of details of the software that will be enabled. For evaluation purposes a trial licence may be used. Before obtaining a full licence you need to know the Kusari hostid of the system on which you intend to use this product. How to do this is described below.
To request a licence key, run the program khostid located in the license/bin/macx64 subdirectory of the software distribution. This utility must be run from a command prompt. Return the information that it displays, together with the product code (in this case NLMI627DGL), by email to NAG. Alternatively, direct the output from this utility to a file and send both the file and the product code to NAG.
A short term (demonstration or trial) licence key contains one or more lines like the following:
NLMI627DG TRIAL 2019/11/12 "EMnxidA3oeoj0F1Yvi5ibxPjB7"Specifically, it has a line containing the word TRIAL. Longer term licence keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These licence keys typically include the word NODE or FULL instead of the word TRIAL above and may contain extra fields.
Once you have obtained one of the above licence keys, the easiest way to install it is to store the text in a file,
$HOME/nag.keyor
/opt/NAG/nag.keyThe licence software in this implementation automatically looks for these particular files and reads the first one found, so no further action is necessary. Alternatively, store the licence in a file with a name and location of your choice, say,
[INSTALL_DIR]/licence.licThe location of the licence file, if it is not one of the default places listed above, must be made known to the NAG application by setting the environment variable NAG_KUSARI_FILE to the full pathname of the file before the application is invoked.
For example, in the C shell, type:
setenv NAG_KUSARI_FILE [INSTALL_DIR]/licence.licor in the Bourne shell, type:
NAG_KUSARI_FILE=[INSTALL_DIR]/licence.lic export NAG_KUSARI_FILE
Further details about Kusari and how it may be configured to suit your local circumstances (e.g. how to install the licence key on a server) are included in the Kusari Licence Management documentation in the license/doc/ subdirectory of the software distribution.
