Installation Debugging Hints

If the user encounters difficulty in the installation process, we suggest the following:

- Obtain prebuilt LAPACK library on netlib for a variety of architectures.

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

- Obtain sample `make.inc` files for a variety of architectures in the `LAPACK/INSTALL` directory in the lapack distribution tar file.
- Consult the LAPACK FAQ list on netlib.
- Consult the `release_notes` file in the lapack directory on netlib. This file contains a list of known difficulties that have been diagnosed and corrected (or will be corrected in the next release), or reported to the vendor as in the case of optimized BLAS.
- Always run the BLAS test suite to ensure that this library has been properly installed. If a problem is detected in the BLAS library, try linking to the reference implementation in the blas directory on netlib.
