This implementation is a compiled, tested, ready-to-use version of the NAG Library that is considered suitable for operation on the computer systems detailed below:
hardware: Marvell ThunderX2 aarch64 systems and compatible operating system: Linux 4.14.0-115.2.2 (glibc-2.17) and compatible Fortran compiler: GNU gfortran 7.4.0 and compatible C compiler: GNU gcc 7.4.0 and compatible
The definitions and sizes of the Integer and Pointer types used in this implementation are shown in Section 3.3 of the Users' Note.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:

The following shows the directory and file organization of the Library Manual materials after installation.
Details of the software are given in the Users' Note (un.html).
Assuming you have downloaded the Library materials from our website as a tar gzip file (clla8262g.tgz), cd to the directory where the file is located and extract the installation materials using the following command:
tar xvzf clla8262g.tgzThis will extract the files install.sh, cl26.tgz, nag_tsandcs.txt, in.html and un.html.
If you have downloaded the Library Manual as a tar gzip file (mk26-2_doc.tgz), move the file into the same location as the Library materials. You can then install the materials from the download directory by executing the shell script install.sh in a command window as:
./install.shBy 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/clla8262g or /opt/NAG/clla8262g 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
