Create the BLAS Library

Ideally, a highly optimized version of the BLAS library already exists on your machine. In this case you can go directly to Section 6.3 to make the BLAS test programs.

a)

Go to LAPACK and edit the definition of blaslib in the file Makefile to specify the data types desired, as in the example in Section 5.3.

If you already have some of the BLAS, you will need to edit the file LAPACK/BLAS/SRC/Makefile to comment out the lines defining the BLAS you have.

b)

Type make blaslib. The make command can be run more than once to add another data type to the library if necessary.

The BLAS library is created in LAPACK/blas_PLAT.a, where PLAT is the user-defined architecture suffix specified in the file LAPACK/make.inc.
