The files require approximately the following disk space:
Library software: 307 MB Library Manual: 310 MB
If you have downloaded the Library materials from our web site as a tar gzip file (flai622dal.tgz), cd to the directory where the file is located and extract the installation materials using the following commands:
gunzip flai622dal.tgz tar xvf flai622dal.tarThis will extract the files install.sh, fl22.tar, in.html and un.html.
If you have downloaded the Library Manual as a tar gzip file (mk22_doc.tgz) run the command
gunzip mk22_doc.tgzto extract the file mk22_doc.tar.
Then follow one of the sets of instructions below to complete the installation.
./install.shBy default, the materials will be installed in /opt/NAG/ or /usr/local/NAG/ depending on your system. You may choose a different location. In this document we refer to the directory /opt/NAG/flai622dal or /usr/local/NAG/flai622dal as [INSTALL_DIR]. This convention is also used in the Users' Note (un.html).
The directory [INSTALL_DIR]/scripts contains one or more scripts to show how to use the libraries provided with this implementation. See Users' Note, Example Programs. Subsequent to the installation, if you move the library to some other location then these scripts must be changed to reflect that fact.
Each library is provided in both static and shareable format. You also have a choice of libraries; self contained libraries which use NAG supplied BLAS and LAPACK or libraries which require the use of vendor supplied BLAS and LAPACK.
To simplify access to the libraries you may wish to create symbolic links in a system location such as /usr/lib pointing at the installed libraries. They would then be in the default search path of the linker during the link phase, and be available for execution at run time (in the case of shareable libraries).
The 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 programs. Their purpose is to allow the Fortran compiler to check that NAG Fortran Library routines are called correctly.
The interface block files (nag_interface_blocks/*) are supplied in both source form and pre-compiled module form. (The source form is only required if the precompiled form is incompatible with the compiler in use.)
The -Ipathname option should then be specified on each compiler invocation (where pathname is [INSTALL_DIR]/nag_interface_blocks/ext or [INSTALL_DIR]/nag_interface_blocks/noext) to tell the compiler where to find the modules (see Users' Note, Interface Blocks).
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.
You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make it readily available to users.
The libraries can be installed manually by following the instructions below:
Move to the directory where you wish to install the product and use the tar utility to extract the materials, e.g.
tar xvf /cdrom/fl22.tarif you are installing from a CD and the CD-ROM has been mounted as /cdrom, or
tar xvf /full path to download directory/fl22.tarif you downloaded the product from our web site.

The directory [INSTALL_DIR]/scripts contains one or more scripts to show how to use the libraries provided with this implementation. These scripts refer to the local directory containing the example programs. The files should be copied to (for example) /usr/local/bin, modified to reflect the local installation, and their protection set to world execute.
To install the Library Manual, move to the directory where you wish to install it and use the tar utility, e.g.
tar xvf /cdrom/mk22_doc.tarif you are installing from a CD and the CD-ROM has been mounted as /cdrom, or
tar xvf /full path to download directory/mk22_doc.tarif you downloaded the installation from our web site.
You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make it readily available to users.
In order to enable the software, NAG will issue you with a license key. The license key is contained in a text file consisting of details of the software that will be enabled.
To request a license key, run the program khostid located in the license/bin/aix64/ 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 FLAI622DAL), by e-mail (or FAX) 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) license key contains one or more lines like the following:
FLAI622DA TRIAL 2008/11/12 "EMnxidA3oeoj0F1Yvi5ibxPjB7"Specifically, it has a line containing the word TRIAL. Longer term 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 word NODE instead of the word TRIAL above.
Once you have obtained one of the above license keys, store the text of it in a file, say
[INSTALL_DIR]/license.lic.The location of the license file 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]/license.licor in the Bourne shell, type:
NAG_KUSARI_FILE=[INSTALL_DIR]/license.lic export NAG_KUSARI_FILE
Further details about Kusari and how it may be configured to suit your local circumstances are included in the Kusari License Management documentation in the license/doc/ subdirectory of the software distribution.
The following material should also be made accessible to users:
documentation files:
The nagdoc_fl22 directory contains the Library Manual. This should be made available to users.
compiled libraries:
libnag_nag.a libnag_nag.so libnag_essl.a libnag_essl.sointerface block files:
nag_interface_blocks/*example program material:
examples/source/??????e.f examples/data/??????e.d examples/results/??????e.r scripts/nag_example*
Note that the example material has been adapted, if necessary, from that published in the Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 3.3 of the Users' Note 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.
