NAG recommends that you read the following minimum reference material before calling any library procedure:
(a) Essential Introduction
(b) Chapter Introduction
(c) Procedure Document
(d) Implementation-specific Users' Note
Items (a), (b) and (c) are included in the NAG fl90 Manual; item (d) is this document which is provided in HTML form.
Assuming that libnagfl90.a has been installed in a directory in the search path of the linker, such as /usr/lib, and that the module information files have been moved to /usr/local/lib/fl90_modules, then you may link to NAG fl90 in the following manner:
f95 -I/usr/local/lib/fl90_modules driver.f90 -lnagfl90where driver.f90 is your application program.
nagexample nag_gen_lin_sys_ex01will copy the example program and its data into the files nag_gen_lin_sys_ex01.f90 and nag_gen_lin_sys_ex01.dat in the current directory and process them to produce the example program results.
A full on-line version of the NAG fl90 Manual is supplied in the form of Portable Document (PDF) files. Please see the Readme file on the distribution medium for further information.
