Hi.

I am trying to compile for the first time the libraries and program of ALPS, so probably this is a very silly question. I am having difficulties making the program to recognize the BLAS and LAPACK libraries.

I install the BLAS and LAPACK libraries that are in

http://www.netlib.org/blas/ http://www.netlib.org/lapack/

These are f77 libraries I normally use, so I am quite sure they are properly installed (at least they never were a problem until now).

After they are installed I copy the .a file into the usual /usr/lib and also to be sure into the ~/home/vijande/ALPS/lib folder and I try to make the instalation of the .configure tool of the instalation with the following options:

./configure --prefix=/home/vijande/ALPS --with-lp_solve=/home/vijande/Fortran/BEC/lp_solve_4.0 --with-blas-lib=/home/vijande/ALPS/lib --with-blas=-lblas --with-lapack-dir=/home/vijande/ALPS/lib --with-lapack=-llapack

and I obtain the following error message:

I tried also with

./configure --prefix=/home/vijande/ALPS --with-lp_solve=/home/vijande/Fortran/BEC/lp_solve_4.0

but the results are identical.

Any idea what I am doing wrong?

Thanks in advance.
