[Lapack] linking/using clapack

First, You have a working clapack library, so this is a very good start.
Now, you just need to add the lapack.a, f2c.a and the BLAS libraries to the 
libraries used in your project. You do not have to move any source files.
You should have a line in your Makefile to add those, just add the path to the 
Hope it helps

To Whom It May Concern,

I am currently working on a molecular dynamics project to convert the source 
code in the Nucleic Acid Builder (NAB) present in the AMBERTOOLS kit from 
double to single precision.  This program is in C and relies on routines from 
lapack for a lot of its functionality.  Unfortunately, when making my 
changes, I discovered that the libraries being used in compilation only 
involved double precision routines so I needed the single precision ones.  
Therefore, I downloaded clapack from and proceeded to 
follow the instructions on the readme.install.  All of the tests directed in 
the readme.install indicate "passed" but when I try to use the source files 
in my clapack/cblas libraries with the program, there are errors.  As 
indicated in the readme.install file, I feel that this may be a result of 
improper linking of libraries.  Unfortunately, I have only had a few 
programming courses and the linking is evading me at the moment.  Please let 
me know if you think you may be able to help me, I can provide the config.h 
and Makefiles being used for the NAB program and anything else you might deem 
helpful.  Thank you for your time and consideration.
