Build Instructions:
------------------

1. Change directory to <Extracted Directory>\LAPACK 3.1.1 for Windows.

2. Execute "set_environment.bat" script from command prompt with the following 
   arguments:
   
   a. Machine architecture to be used:
      This parameter is mandatory and currently 32-bit and 64-bit machine 
      architectures are supported.

   b. Compiler to be used:
      This parameter is mandatory and currently Intel and PGI compilers are 
      supported.

   c. BLAS library to be used:
      This parameter is optional and by default it uses BLAS library shipped
      with the package.
 
   Here is the usage of the set_environment.bat script:

   set_environment.bat <x86 | x64> <Intel | PGI> [BLAS Library Path]

   Type /? to get the help/usage message on command prompt.

3. Please execute "nmake cleanall" command if you have built the package 
   earlier in different environment i.e. by using different compiler and/or
   for different machine architecture.

4. Type 'nmake /NOLOGO all' on command prompt to build and test LAPACK package.

Notes: 
      - It is recommended to use new terminal to setup the development 
        environment for buidling LAPACK for different machine architecture
        and/or using different compiler.

      - If you have not installed PGI compiler at default location, modify
        set_environment.bat script to specify approprite path of pgi_dos.bat.

      - LAPAACK Fortran Interface:
 
        a. Using 64-bit PGI compiler:
           The FORTRAN interface names are similar to AMD's 64-bit ACML library
           and they can be called directly.

        b. Using 32-bit PGI compiler:
           The FORTRAN interface names are similar to AMD's 32-bit ACML library 
           and they can be invoked by providing -Munix flag to the pgf77 
           compiler.

        c. Using 64-bit Intel compiler:
           The FORTRAN interface names are similar to AMD's ACML and Intel's
           MKL 64-bit library and they can be called directly.

        d. Using 32-bit Intel compiler:
           The FORTRAN interface names are similar to AMD's ACML and Intel's
           MKL 32-bit library and they can be called directly.
