Installation of LAPACK

To ease the installation process, prebuilt LAPACK libraries are available on netlib for a variety of architectures.

> `http://www.netlib.org/lapack/archives/`

Included with each prebuilt library archive is the make include file `make.inc` detailing the compiler options, and so on, used to compile the library. If a prebuilt library is not available for the specific architecture, the user will need to download the source code from netlib

> `http://www.netlib.org/lapack/lapack.tgz`
> `http://www.netlib.org/lapack/lapack-pc.zip`

and build the library as instructed in the LAPACK Installation Guide [3,37]. Note that separate distribution tar/zip files are provided for Unix/Linux and Windows 98/NT installations. Sample `make.inc` files for various architectures are included in the distribution tar/zip file and will require only limited modifications to customize for a specific architecture.

Machine-specific installation hints are contained in the `release_notes` file on netlib.

> `http://www.netlib.org/lapack/release_notes`

A comprehensive test suite for the BLAS is provided in the LAPACK distribution and on netlib, and it is highly recommended that this test suite, as well as the LAPACK test suite, be run to ensure proper installation of the package.

Two installations guides are available for LAPACK. A Quick Installation Guide (LAPACK Working Note 81) [37] is distributed with the complete package. This Quick Installation Guide provides installation instructions for Unix/Linux systems. A comprehensive Installation Guide [3] (LAPACK Working Note 41), which contains descriptions of the testing and timings programs, as well as detailed non-Unix installation instructions, is also available. See also Chapter 6.
