In addition, NAG recommends that before calling any library routine you should read the following reference material (see Section 5):
(a) Essential Introduction
(b) Chapter Introduction
(c) Routine Document
Assuming that libnagc_nag.a and libnagc_nag.dylib have been installed in a directory in the search path of the linker, such as /usr/lib, and that the NAG include files have been moved to /usr/include, then you may link to the NAG C Library in the following manner:
cc driver.c -lnagc_nag -lpthread -lmwhere driver.c is your application program.
If the include files are in a location other than /usr/include, such as /usr/local/include, then you may link to the NAG C Library in the following manner:
cc -I/usr/local/include driver.c -lnagc_nag -lpthread -lm
The linker will, by default, pick up the shared library (libnagc_nag.dylib). To force the use of the static library you will have to specify it in full on your command line:
cc driver.c /usr/lib/libnagc_nag.a -lpthread -lm
Each command will provide you with a copy of an example program (and its data, if any), compile the program and link it with the appropriate libraries (showing you the compile command so that you can recompile your own version of the program). Finally, the executable program will be run, presenting its output to stdout.
The example program concerned is specified by the argument to the command, e.g.
will copy the example program into the file d01ajce.c in the current directory and process it to produce the example program results.
The example programs are supplied in machine-readable form. They are suitable for immediate usage. Note that the distributed example programs are those used in this implementation and may not correspond exactly with the programs published in the manual. The distributed example programs should be used in preference wherever possible.
The distributed example results are those obtained with the NAG self-contained static library libnagc_nag.a, (using the NAG BLAS and LAPACK routines).

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 (CLAMP08DAL).
