I'm not exactly sure what your problem is, but maybe this will help:

1. You need a Fortran compiler, unless you want to use CLAPACK.

2. Get LAPACK from netlib: http://netlib.org/lapack/index.html. There are
several ZIP files out there for Windows, including lapack-pc.zip,
lapack-pc-df.zip and lapack-pc-wfc.zip. Pick one that most closely matches
your Fortran compiler.

3. You can try using the supplied makefiles to build and test, but I tend to
use my development environment (Visual Studio for me) to create a static
library that I can then link into any program that needs it.

4. The speed of LAPACK is very dependent on the quality of your BLAS. The
reference implementation from netlib will work, but you will not get the
"best" performance.

5. If you really intend on making a lot of use of LAPACK, buy a Fortran
compiler that comes with BLAS/LAPACK, such as Compaq Visual Fortran. CVF is
no longer in development, however. Intel Visual Fortran is the replacement,
but you need to purchase the Intel MKL library to get BLAS/LAPACK.

6. If you are not married to Windows XP, you can try the switch to Linux,
and then you might be able to get good BLAS/LAPACK libraries for free. I
believe even Intel supplies free versions of its compilers and MKL for
non-commercial use.
